Today, in 2026, gas cars are still running and gas price fluctuated around $3/$4 over the past 5 years.</p><p>In the 2000s, after making the movie &#8220;<a href="https://en.wikipedia.org/wiki/An_Inconvenient_Truth">An inconvenient truth</a>&#8221;, Al Gore claimed the Arctic ice will be gone in a matter of months. As of today, the Arctic Ice is still here.</p><p>In 2019, Alexandria Ocasio-Cortez <a href="https://www.newsweek.com/alexandria-ocasio-cortez-climate-change-world-will-end-12-years-un-report-1300873">warned us</a> that the &#8220;World Is Going to End in 12 Years&#8221;. Just 7 years after such a claim, I am pretty confident the world will still be around in 2031.</p><div><hr></div><p>Fear sells everywhere - this is one of the greatest marketing technique (just think about the FOMO many experience on a regular basis), this is why salespeople or politicians use it everywhere to sell their product (be a security system, a miraculous medication or a revolutionary program that will lower your tax and get you more public services at the same time!).</p><p>And today, a new fear just landed in our societal landscape: AI, job displacement and more globally, search for meaning. You hear politicians and influencers claims that &#8220;data center will turn your water brown&#8221; or that &#8220;AI is going to take your job&#8221;, triggering anxiety among the working class and ultimately questioning our existence and meaning (what will we do if we have no job?).</p><div><hr></div><p>Instead of fear, I prefer to choose hope and believe in ourselves.</p><p>We are resilient and every time we face serious issues, we were able to figure them out and overcome our problems. And instead of listening to uneducated salespeople pushing their own agenda, we&#8217;d rather think for ourselves and evaluate if a change is good or not for society.</p><p>When it comes to AI, there is a lot to figure out today but there is no question there is a big potential for us. Like with any technology, we will need to adapt but we will grow as a society and get better. Instead of rejecting technology without any good reason, we should wonder how we can use it for the greater good.</p><p></p>]]></content:encoded></item><item><title><![CDATA[Local, open-source models are the future]]></title><description><![CDATA[Anthropic and OpenAI are the Netscape of this era]]></description><link>https://techramblings.blog/p/local-open-source-models-are-the</link><guid isPermaLink="false">https://techramblings.blog/p/local-open-source-models-are-the</guid><dc:creator><![CDATA[Julien]]></dc:creator><pubDate>Mon, 15 Jun 2026 23:24:53 GMT</pubDate><enclosure url="https://substackcdn.com/image/fetch/$s_!ZKd1!,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fd3bc5cf2-ba10-4166-8465-3ecd5959f9d5_640x480.jpeg" length="0" type="image/jpeg"/><content:encoded><![CDATA[<p>Sixty years ago, owning a computer meant having a mainframe operated by a dedicated team.

Companies buy SaaS applications to focus on their core business instead of going on side quests and implementing and maintaining some random software. A food business or a hardware store working on a website does not want to re-implement Slack, build an AWS replica, or re-implement Twilio. And the last thing they want is to re-implement an internal copycat of Workday (with all its legal subtleties) to handle HR concerns.</p><p>The few adventurous who want to embark on such a re-implementation crusade will ultimately need to hire engineers to maintain their custom software and ensure compliance with all applicable laws. Unless the company operates at a massive scale, the maintenance expenses will be far bigger than buying the SaaS equivalent.</p><p>On the other hand, the impact of agentic coding will lower the barrier to entry to build competitors to existing SaaS products. It will lead to more competition and, ultimately, more options for the customers, which is a good thing. It will also put pressure on existing players to deliver more value and/or lower their prices (and potentially, their margin).</p><div class="subscription-widget-wrap-editor" data-attrs="{&quot;url&quot;:&quot;https://techramblings.blog/subscribe?&quot;,&quot;text&quot;:&quot;Subscribe&quot;,&quot;language&quot;:&quot;en&quot;}" data-component-name="SubscribeWidgetToDOM"><div class="subscription-widget show-subscribe"><div class="preamble"><p class="cta-caption">Thanks for reading Tech Ramblings!

When something good happens to us, our goal should be to make the best out of it and enjoy it at its fullest while it lasts.</p><p>The hard part is to leave while it&#8217;s still good, almost at the top, and avoid dragging a falling project or a dying relationship for months or years. Too often, people keep working on a project even when it degrades or gets bad, hoping greatness will come back or trying desperately to milk some last bits of success. This is a losing game: you will not only lose your time, but people will always remember these last painful moments.</p><p>You need to stop at the top, before quality erodes. Admit that the best happened and move on to your next venture.

The book goes into how Walton started and expanded Walmart from his first variety store into the retail juggernaut Walmart is today. There are a few striking points in the book about either entrepreneurship or the status of our society and country.</p><h2>Innovator Traits</h2><p>Walton understood early on (in the 1950s) that discount stores (defined mostly by small margins and high volume) would take over variety stores. He was customer-obsessed since day one and relentlessly tried to innovate. Walton was not afraid to copy his competitors. Walton always visited stores everywhere in the country and took notes on his legal pad or using his microphone. There was no ego involved and Walton does not hesitate to credit <a href="https://en.wikipedia.org/wiki/Sol_Price">Sol Price</a> (the creator of FedMart and Costco) for many ideas.</p><p>Many ideas we see in tech today (e.g., customer obsession at Amazon or scaling laws) were already in place at Walmart, and they directly influenced companies like Amazon.</p><h2>Status did not matter</h2><p>Walton bought some expensive houses once he became a billionaire but never tried to impress anybody with a lavish lifestyle. He stayed true to some core values and principles. Many associates tell stories where he often shared hotel rooms with his employees on business trips or sometimes skipped paying the hotel and slept directly at an associate house.</p><p>Walton also reflects on his life and admits his mistakes, either professionally (e.g., when he was too late to open a new warehouse or when he was not giving enough recognition to his employees) or personally (e.g., not recognizing enough women in the retail industry - his wife changed his mind on this topic).</p><h2>Build Stuff People Want</h2><p>Walton success thesis is simple: build something customers want. For the Walmart case, variety stores had high margins, had limited opening hours, and some did not treat the customer well. Walton reduced prices, opened stores every day, and made sure the customer was treated properly (have you seen the greeters at Walmart?). </p><p>These are extremely elementary principles, and yet, the competition did not understand them and failed to execute.</p><p>The same principles guide many startups today. Even YCombinator had the motto <a href="https://www.paulgraham.com/good.html">&#8220;Make something people want&#8221;</a>. Walton did not invent this concept, but he applied startup principles of today back in 1940, and it worked extremely well.</p><h2>Keep Operating</h2><p>Walton always stays true to some simple business principles and keeps operating according to them. For example, a key principle was to always pass any savings to the customers. Another one was to always treat associates right (at least, during his tenure as CEO). He never lowered his standards. He changed them sometimes when it made sense but never compromised.</p><p>Even when Wall-Street and other analysts were calling him done, he kept operating according to his plan and refused to change because of some trend or financial analysts called Walmart as done.</p><p>Walton weathered many storms in his career, and every time, what saved him was to stay true his fundamentals: listen to the people who cared about him since the beginning, focus on bringing value to the customers, and grow organically.</p><p>The same applies in startups: we may see many ups and downs and trends. But in the end, what matters is to build something users love and deliver value.</p><div class="subscription-widget-wrap-editor" data-attrs="{&quot;url&quot;:&quot;https://techramblings.blog/subscribe?&quot;,&quot;text&quot;:&quot;Subscribe&quot;,&quot;language&quot;:&quot;en&quot;}" data-component-name="SubscribeWidgetToDOM"><div class="subscription-widget show-subscribe"><div class="preamble"><p class="cta-caption">Thanks for reading Tech Ramblings!

I think they are lost and rather in search of meaning.</p><h2>Apple&#8217;s original core vision</h2><p>The original core vision of Apple was to build the best products on earth. And they did it at the best price they could, but never at the cost of quality or user experience. And they fulfilled their mission: to this day, many Apple products are unmatched.</p><p>Through the first 30 years of existence, Apple defined key tenets for the brand:</p><ul><li><p>differentiated branding and marketing (people still mention <a href="https://en.wikipedia.org/wiki/1984_(advertisement)">the 1984 ad </a>that the Apple board originally refused)</p></li><li><p>premium design, either software (iOS, macOS) or hardware (Macbook, iPhone) &#8212; Apple ships the best product; they <a href="https://www.youtube.com/watch?v=eAo8gnUCWzE&amp;t=22s">do not ship junk</a></p></li><li><p>world-class user experience</p></li><li><p>privacy-first: people pay for the product</p></li></ul><p>Through the years, Apple managed to innovate and ship products that redefined our industry. Jobs said it better than anyone at the launch of the iPhone.</p><blockquote><p><em>Every once in a while, a revolutionary product comes along that changes everything and Apple has been &#8211; well, first of all, one&#8217;s very fortunate if you get to work on just one of these in your career. Apple has been very fortunate. It&#8217;s been able to introduce a few of these into the world.</em></p></blockquote><p>However, since 2007, Apple stopped innovating.</p><p>Instead of staying an innovation machine, Apple became an iteration machine. They no longer ship products that redefine an industry. They ship iterations or marginal improvements of existing products.</p><h2>Search for Meaning</h2><h3>What&#8217;s next after the iPhone?</h3><p>Tim Cook surfed the wave started by the iPhone tsunami. He squeezed every penny from it: Apple made some features <a href="https://notes.nokun.eu/post/2024-05-26-expensive-laptops-dont-pro/">extremely expensive</a> and they forced developers to pay a 30% Apple tax on every sale within an iOS app. Anything Apple launched since the iPhone is not a breakthrough innovation; it&#8217;s a marginal improvement.</p><p>Tim Cook managed to make Apple a remarkable company from a financial standpoint, but he failed to keep the innovation flywheel going.</p><p>The issue for Apple is to find the next big thing.</p><p>For some time, people believed it was the Apple Car. But after years of development and refusing to buy Tesla in 2017, the project got canceled. Apple stopped iterating on this idea, even if they had billions in the bank to do so.</p><p>The recent flop of the Apple Vision Pro gives us a better peek at the change of culture at Apple. Despite the technological achievements, Apple needs to face the fact that nobody wants to spend $4500 to live with googles strapped on their face.</p><p>There is more evidence that Apple is lost and unable to ship anything significant. When we see major improvements in AI every day, Siri is still struggling.</p><h3>What values?</h3><p>Apple has been one of the best brands in terms of marketing. The brand positioned itself as a premium brand, and their advertisements were designed accordingly (see <a href="https://www.youtube.com/watch?v=-z4NS2zdrZc">&#8220;Here&#8217;s to the crazy ones&#8221;</a>). They communicated their values very well: innovative, great to use, and user-friendly.</p><p>But today, such values are gone, and Apple is lost.</p><p>Take <a href="https://www.youtube.com/watch?v=QNv9PRDIhes">the Apple commercial about the environmental footprint</a>. The ad made the Apple CEO Tim Cook like a child being lectured by a morbidly obese &#8220;Mother Nature&#8221;. The ad is childish and makes the Apple CEO appear stupid and out of touch. Jobs would clearly never have approved this (he mentioned once that one of his biggest mistakes was to make a teleconference with Bill Gates where he appeared on top of him).</p><div class="captioned-image-container"><figure><a class="image-link image2 is-viewable-img" target="_blank" href="https://substackcdn.com/image/fetch/$s_!gKJ5!,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F11d2dc96-862e-4868-b1e5-73d7ac92bd0c_2464x1986.jpeg" data-component-name="Image2ToDOM"><div class="image2-inset"><picture><source type="image/webp" srcset="https://substackcdn.com/image/fetch/$s_!gKJ5!,w_424,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F11d2dc96-862e-4868-b1e5-73d7ac92bd0c_2464x1986.jpeg 424w, https://substackcdn.com/image/fetch/$s_!gKJ5!,w_848,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F11d2dc96-862e-4868-b1e5-73d7ac92bd0c_2464x1986.jpeg 848w, https://substackcdn.com/image/fetch/$s_!gKJ5!,w_1272,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F11d2dc96-862e-4868-b1e5-73d7ac92bd0c_2464x1986.jpeg 1272w, https://substackcdn.com/image/fetch/$s_!gKJ5!,w_1456,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F11d2dc96-862e-4868-b1e5-73d7ac92bd0c_2464x1986.jpeg 1456w" sizes="100vw"><img src="https://substackcdn.com/image/fetch/$s_!gKJ5!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F11d2dc96-862e-4868-b1e5-73d7ac92bd0c_2464x1986.jpeg" width="1456" height="1174" data-attrs="{&quot;src&quot;:&quot;https://substack-post-media.s3.amazonaws.com/public/images/11d2dc96-862e-4868-b1e5-73d7ac92bd0c_2464x1986.jpeg&quot;,&quot;srcNoWatermark&quot;:null,&quot;fullscreen&quot;:null,&quot;imageSize&quot;:null,&quot;height&quot;:1174,&quot;width&quot;:1456,&quot;resizeWidth&quot;:null,&quot;bytes&quot;:null,&quot;alt&quot;:&quot;Bill Gates beams into the 1997 Macworld conference, pledging a $150 million  investment in his struggling competitor while the crowd jeers and boos.

The winners from 6 months ago are the losers of tomorrow. New AI technologies, habits and tools change faster than the geopolitical climate in the US. Yesterday, all the AI hype was about Cursor but today, everything is about Gemini and Claude Code.</p><p>The early players are now irrelevant (who still talk about GitHub copilot?), and model providers are doing everything possible to go beyond the API and capture the value delivered at the application level. We are seeing this with coding tools (Anthropic with Claude Code, OpenAI with Codex, Google with Gemini CLI) and it starts to happen in other domains as well (see <a href="https://www.anthropic.com/solutions/financial-services">Claude for financial services</a> or even the AI companions from Grok).</p><p>There is the workflow I use today for:</p><ul><li><p><strong>search</strong>: any search is done with ChatGPT desktop. When alone/at home, I rely on voice mode and type when in the office. I rarely use Google anymore and when searching, use alternative search engines (brave or kagi)</p></li><li><p><strong>large coding tasks</strong>: I use Claude Code (at work) or Gemini (at home) for any coding tasks larger than 2 lines. Both Claude Code and Gemini have similar performance and write 90%+ of the code I ship today.</p></li><li><p><strong>refining code</strong>: I use whatever is integrated in my IDE to refine the generated code and complete a line. IDEs like JetBrains have internal inline completion that are pretty good and free. Users now expect IDEs to have a good inline completion out of the box.</p></li></ul><p>I feel we are still not in the final stage of what AI-enabled development tools can do. We may abstract them more and instead of writing code in the command line, integrate them into projects management tools (e.g. Jira). Claude Code or Gemini CLI may be the cool kids today but I wouldn&#8217;t be surprised if new tools come in a few months with a better integration into the developer workflow.</p><div class="subscription-widget-wrap-editor" data-attrs="{&quot;url&quot;:&quot;https://techramblings.blog/subscribe?&quot;,&quot;text&quot;:&quot;Subscribe&quot;,&quot;language&quot;:&quot;en&quot;}" data-component-name="SubscribeWidgetToDOM"><div class="subscription-widget show-subscribe"><div class="preamble"><p class="cta-caption">Thanks for reading Tech Ramblings!

In this post, I give an overview of <a href="https://aider.chat/">aider</a>, another open-source coding agent that uses different architectural choices. The objective is to look at some differences in the overall architecture of two coding agents. I will skip the introduction part about agents (you can read the <a href="https://juli1.substack.com/p/anatomy-of-a-coding-agent">previous post</a> for that) and go directly in what differentiates aider.</p><h2>General Design Choices</h2><p>Aider is developed in Python, which is the language of choice when it comes to write ML applications. Where opencode uses the <a href="https://ai-sdk.dev/">Vercel AI SDK</a>, aider relies on the <a href="https://docs.litellm.ai/">Python litellm</a> to stay platform agnostic. Like opencode, it can interface with many models, either remote or local (if you use ollama).</p><p>A good entry point is the <a href="https://github.com/Aider-AI/aider/blob/f22fbf9b3ae20361c23dfbd989929e25cd3ccd61/aider/coders/base_coder.py#L2">base_coder.py</a> file that contains the main iteration loop. The file <a href="https://github.com/Aider-AI/aider/blob/f22fbf9b3ae20361c23dfbd989929e25cd3ccd61/aider/models.py#L947">models.py</a> contains the code that initialize the models (along with the tools). </p><h2>Multiple Modes, Multiple Agents</h2><p>Aider provides multiple modes, each of them has its own prompts and set of tools. For each mode, there is a new agent, built around a new prompt.</p><ul><li><p>code</p></li><li><p>ask (<a href="https://github.com/Aider-AI/aider/blob/f22fbf9b3ae20361c23dfbd989929e25cd3ccd61/aider/coders/ask_prompts.py#L17">prompts</a>)</p></li><li><p>architect (<a href="https://github.com/Aider-AI/aider/blob/f22fbf9b3ae20361c23dfbd989929e25cd3ccd61/aider/coders/architect_prompts.py#L16">prompts</a>)</p></li></ul><p>These agents have the same capacity (e.g. tools), the main difference is the initial prompt passed to them.</p><h2>Code Indexing</h2><p>Coding agents index your code incrementally. When you open a repository for the first time, the agent indexes the entire codebase and updates the index incrementally upon code changes. Aider supports all languages supported by the <a href="https://github.com/Goldziher/tree-sitter-language-pack">tree-sitter-language-pack</a>, a collection of well-maintained tree-sitter grammars.</p><p>Aider indexes the code through a <a href="https://aider.chat/docs/repomap.html">Repository Map</a>, where it extracts symbols (also known as tags) definition (class or function/method definition) and reference (e.g. there the symbols are being used). This is implemented through tree-sitter queries that run queries (<a href="https://github.com/Aider-AI/aider/blob/main/aider/queries/tree-sitter-languages/java-tags.scm">example of queries for Java</a>) against each file. It qualifies the type of tag based <a href="https://github.com/Aider-AI/aider/blob/main/aider/repomap.py#L299-L305">on the name associated with the query</a>.</p><p>This information is then saved in a SQLite database to make it available at the next execution and easily query it. The SQLite database is abstracted by the <a href="https://grantjenks.com/docs/diskcache/">diskcache</a> library.</p><h2>Prompt Building</h2><p>The prompt itself is built using some base strings (as shown in <a href="https://github.com/Aider-AI/aider/blob/f22fbf9b3ae20361c23dfbd989929e25cd3ccd61/aider/coders/ask_prompts.py#L11">ask_prompts.py</a> or <a href="https://github.com/Aider-AI/aider/blob/f22fbf9b3ae20361c23dfbd989929e25cd3ccd61/aider/coders/architect_prompts.py#L8">architect_prompts.py</a>). Then, the prompt is augmented with the code structure, which comes from the code index (aka repomap in the aider terminology). The enrichment logic resides in the <a href="https://github.com/Aider-AI/aider/blob/f22fbf9b3ae20361c23dfbd989929e25cd3ccd61/aider/repomap.py#L610">repomap.py</a> file and it attempts to pack the most information in the number of tokens available by ranking the data.</p><p>The code index sent to the prompt contains the class and function definition signatures. It&#8217;s enough to understand the structure of the code but it does not contains any information about the implementation of the function itself.</p><h2>Comparing opencode and aider</h2><p>The goal is not to compare the performance of the tools but the commonalities in the architecture.

Most of them have a good performance, not because the underlying tooling is amazing but just <a href="https://jamesgrugett.com/p/what-i-learned-building-an-ai-coding">because the underlying models are extremely good</a>. Building a coding agent is becoming easier at each model iteration. I am not saying this is trivial, but the barrier to entry for building something good is lower than a year ago. In this post, I explain the main components that make a coding agent. </p><p><a href="https://github.com/opencode-ai/opencode">Opencode</a> is an open-source coding agent. It&#8217;s similar to <a href="https://aider.chat/">aider</a>, another coding agent that I will review in another post. Note that there are different flavors/forks of opencode, I will use the <a href="https://github.com/sst/opencode">sst repository</a> to explain the code. </p><div class="subscription-widget-wrap-editor" data-attrs="{&quot;url&quot;:&quot;https://techramblings.blog/subscribe?&quot;,&quot;text&quot;:&quot;Subscribe&quot;,&quot;language&quot;:&quot;en&quot;}" data-component-name="SubscribeWidgetToDOM"><div class="subscription-widget show-subscribe"><div class="preamble"><p class="cta-caption">Thanks for reading Tech Ramblings!

From a technical perspective, an agent is a program that keeps calling an tool-augmented LLM until a condition is met. By <em>&#8220;tool-augmented LLM&#8221;</em>, I refer to a call to the LLM paired with some tools<a class="footnote-anchor" data-component-name="FootnoteAnchorToDOM" id="footnote-anchor-1" href="#footnote-1" target="_self">1</a> (edit a file, read a file, fetch some documents online, send a text, etc) to augment its capabilities. </p><p>From a programming perspective, an agent is a <code>while</code> loop that keeps calling the LLM until a final condition is satisfied (for example, passing a text, getting the answer <em>&#8220;yes&#8221;</em> by voice or just getting an answer from the model). The LLM is augmented with tools to make progress on a task, be it reading a file, editing a file, getting semantic information or doing websearch. To give a concrete example, when ChatGPT searches the internet for you, it uses a web search tool to find information on the internet for you. Coding agents use tools that read files, grep the codebase or call <a href="https://en.wikipedia.org/wiki/Language_Server_Protocol">LSP-related features</a> (find a symbol definition, list the functions with a specific name, etc).</p><p>The mental model to keep in mind is something like the snipper below. The <code>callLLM()</code> function is where the tools are added to the LLM call.</p><pre><code>while (true) {
  result = callLLM(message)
  if (isFinalConditionMet(result)) {
    exit()
  }
  message = updateMessage()
}
</code></pre><h2>Coding Agent in a Nutshell</h2><p>Your coding agent is simply iterating on messages sent to an LLM until your condition is met. The agent sends in its message the list of tools available and the argument of the tools. The LLM returns either some text or requests the agent to invoke some tools. You can see a very simplistic message sequence of how this would work for a very simple function creation.</p><p>OpenAI has some <a href="https://platform.openai.com/docs/guides/function-calling?api-mode=responses">good documentation</a> about tools, the important part is that all tools are executed locally.</p><div

provider has its own way to call a model and handle tools, making it hard to switch models. Opencode uses the <a href="https://ai-sdk.dev/">AI SDK from Vercel</a>, which abstract model providers and lets developers write provider-agnostic AI agents.</p><p>The core of the model orchestration is done in <a href="https://github.com/sst/opencode/blob/dev/packages/opencode/src/session/index.ts">session/index.ts</a> through the function <code>streamText()</code>. Initializing the models along with the tools is done in <a href="https://github.com/sst/opencode/blob/dev/packages/opencode/src/provider/provider.ts">provider/provider.ts</a>.</p><p>The beauty of using such a framework is simple: you can focus on building the core of your application without having to worry about what platform or AI framework you can use. Any developer building an AI application should rely on such a library (<a href="https://ai-sdk.dev/">AI SDK for TypeScript</a>, <a href="https://www.langchain.com/">Langchain for Python</a>) to avoid any platform dependence.</p><h2>Prompt quality matters a lot</h2><p>The prompt size is no longer a major constraint but the quality of the prompt is really what matters. Editing or analyzing a monorepo with 1000 files and trying to update only 2 files is like finding a needle in a haystack. And to make your LLM finding the needle, you better give it really good instructions.</p><p>This is why the quality of your prompt matters. <strong>A lot.</strong> </p><p>The <a href="https://github.com/sst/opencode/blob/dev/packages/opencode/src/session/prompt/anthropic.txt">prompt for opencode</a> is quite long and gives a ton of examples of what to follow. There are some general guidelines to follow for a good prompt:</p><ul><li><p>be extremely explicit about what you want. If something matters, use CAPITAL LETTERS TO INDICATE YOU CARE ABOUT A PARTICULAR INSTRUCTION.</p></li><li><p>keep using Markdown to write your prompt. Hierarchical information with titles using the # character and very important information using <strong>***BOLD***</strong></p></li><li><p>use special tokens to specify examples, like <code>&lt;example&gt;</code></p></li></ul><p>Once you have a good basic prompt, you need to be able to augment it with tools that provides the necessary features to find the needle in the haystack.</p><h2>Augment LLM with tools</h2><p>Tools are the real coding agent "magic sauce". An LLM without tools is like Bruce Wayne. With the tools, it becomes Batman and can save developers from hours of debugging.</p><p>Common tools for coding agents are: grep, read file or write a file. All tools for opencode are located in <a href="https://github.com/sst/opencode/tree/dev/packages/opencode/src/tool">packages/opencode/src/tool</a> and added to the LLM in <a href="https://github.com/sst/opencode/blob/dev/packages/opencode/src/provider/provider.ts">provider/provider.ts</a>. All coding agents (including Cursor, Claude Code, etc) rely only on two things:</p><ul><li><p>the quality of the prompt</p></li><li><p>the quality and accuracy of the tools</p></li></ul><p>The important part of the tool is to correctly specify what the tool does through a clear description (like <a href="https://github.com/sst/opencode/blob/dev/packages/opencode/src/tool/glob.txt">this one</a>) and parameters (like <a href="https://github.com/sst/opencode/blob/dev/packages/opencode/src/tool/glob.ts#L11-L18">those ones</a>). These tools are then called to the LLM and the program loops with the tool results until the LLM is finished.</p><p>I insist that the quality of the tools contributes significantly to the quality of your coding agent. This is why all popular coding agent (Cursor) index your codebase: they index symbols to easily feed accurate data to the model. Similar to the tool to get a line of code (many LLM struggle to find a line of code accurately) or edit files: small tweaks can have major effects on the overall tool quality. This is why having good evals help you quickly iterate on the quality of your product.</p><h2>Ask the Agent to Plan</h2><p>Opencode has an interesting approach: it provides a TODO list tool to the agent. The initial prompt <a href="https://github.com/sst/opencode/blob/dev/packages/opencode/src/session/prompt/anthropic.txt#L83-L151">explains how the TODO list works</a> and the tools available to <a href="https://github.com/sst/opencode/blob/dev/packages/opencode/src/tool/todoread.txt">read</a> and <a href="https://github.com/sst/opencode/blob/dev/packages/opencode/src/tool/todowrite.txt">write</a> the TODO list.</p><p>The agent constantly uses this todo list tool to keep track of what to do and in what order.</p><h2>Why coding agents cost so much to operate?</h2><p>Since the release of Claude Code, users complained about the cost.</p><div class="captioned-image-container"><figure><a class="image-link image2" target="_blank" href="https://substackcdn.com/image/fetch/$s_!XDb5!,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F998080f3-16d1-4b4b-94f0-bfab4c5041eb_730x103.png" data-component-name="Image2ToDOM"><div class="image2-inset"><picture><source type="image/webp" srcset="https://substackcdn.com/image/fetch/$s_!XDb5!,w_424,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F998080f3-16d1-4b4b-94f0-bfab4c5041eb_730x103.png 424w, https://substackcdn.com/image/fetch/$s_!XDb5!,w_848,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F998080f3-16d1-4b4b-94f0-bfab4c5041eb_730x103.png 848w, https://substackcdn.com/image/fetch/$s_!XDb5!,w_1272,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F998080f3-16d1-4b4b-94f0-bfab4c5041eb_730x103.png 1272w, https://substackcdn.com/image/fetch/$s_!XDb5!,w_1456,c_limit,f_webp,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F998080f3-16d1-4b4b-94f0-bfab4c5041eb_730x103.png 1456w" sizes="100vw"><img src="https://substackcdn.com/image/fetch/$s_!XDb5!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F998080f3-16d1-4b4b-94f0-bfab4c5041eb_730x103.png" width="730" height="103" data-attrs="{&quot;src&quot;:&quot;https://substack-post-media.s3.amazonaws.com/public/images/998080f3-16d1-4b4b-94f0-bfab4c5041eb_730x103.png&quot;,&quot;srcNoWatermark&quot;:null,&quot;fullscreen&quot;:null,&quot;imageSize&quot;:null,&quot;height&quot;:103,&quot;width&quot;:730,&quot;resizeWidth&quot;:null,&quot;bytes&quot;:18493,&quot;alt&quot;:null,&quot;title&quot;:null,&quot;type&quot;:&quot;image/png&quot;,&quot;href&quot;:null,&quot;belowTheFold&quot;:true,&quot;topImage&quot;:false,&quot;internalRedirect&quot;:&quot;https://juli1.substack.com/i/167774785?img=https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F998080f3-16d1-4b4b-94f0-bfab4c5041eb_730x103.png&quot;,&quot;isProcessing&quot;:false,&quot;align&quot;:null,&quot;offset&quot;:false}" class="sizing-normal" alt="" srcset="https://substackcdn.com/image/fetch/$s_!XDb5!,w_424,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F998080f3-16d1-4b4b-94f0-bfab4c5041eb_730x103.png 424w, https://substackcdn.com/image/fetch/$s_!XDb5!,w_848,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F998080f3-16d1-4b4b-94f0-bfab4c5041eb_730x103.png 848w, https://substackcdn.com/image/fetch/$s_!XDb5!,w_1272,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F998080f3-16d1-4b4b-94f0-bfab4c5041eb_730x103.png 1272w, https://substackcdn.com/image/fetch/$s_!XDb5!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F998080f3-16d1-4b4b-94f0-bfab4c5041eb_730x103.png 1456w" sizes="100vw" loading="lazy"></picture><div></div></div></a></figure></div><p>The team behind Claude Code even discussed this in the <a href="https://youtu.be/zDmW5hJPsvQ?si=wn_ML9ulivUSJQjV&amp;t=771">Latent Space podcast</a>, explaining that some users at Anthropic can spend thousands of dollars a day. While this is probably an extreme case, this shows this is a valid concern. Cursor probably did not have this problem yet because usage was heavily subsidized by VC money.</p><p>Coding agents are expensive because of how they are implemented: we pass a ton of token in the prompt and context. When your typical ChatGPT request contains a few hundred tokens at most, a coding agent will consumer ten of thousands of tokens per request. If you constantly vibe code as the cool kids do today, it will very quickly be extremely expensive.</p><p>I believe this is not a real problem and we have seen that story before. VC subsidized Uber for years until users were hooked on the platform and were ready to pay the real cost of a ride. Amazon subsidized many products to establish dominance and eventually reach economies of scale. There is no doubt that coding agents are here to stay ; the current economic model may have to evolve. </p><h2>What is coming next?</h2><p>I can see mostly two major improvements in the coming months:</p><ol><li><p><strong>Running locally</strong>: projects like <a href="https://ollama.com/">ollama</a> make it really easy to run LLM locally.

You should avoid execution risks and only embark on a difficult journey if this is justified by the potential business outcomes.</p><div class="subscription-widget-wrap-editor" data-attrs="{&quot;url&quot;:&quot;https://techramblings.blog/subscribe?&quot;,&quot;text&quot;:&quot;Subscribe&quot;,&quot;language&quot;:&quot;en&quot;}" data-component-name="SubscribeWidgetToDOM"><div class="subscription-widget show-subscribe"><div class="preamble"><p class="cta-caption">Thanks for reading Tech Ramblings!

Education, medicine or even transportation: all sectors will be impacted.</p><p>One key question is what happens to us as humans.</p><p>Are we staying relevant in this new world?</p><p>It seems just a matter of years before we clone ourselves<a class="footnote-anchor" data-component-name="FootnoteAnchorToDOM" id="footnote-anchor-1" href="#footnote-1" target="_self">1</a>. Our style, our thought process, or even our voice. All of what makes us &#8220;unique&#8221; (or what we thought so) will be replicated in a few GB or TB of data. A multi-modal model will be able to mimic your personality and let us live in the cyberspace. Your clone will interact with others through audio, video, or text. Similar to the episode <a href="https://en.wikipedia.org/wiki/Be_Right_Back">Be Right Back</a> of Black Mirror, virtually talking to loved ones who die will be possible. As technology progresses, the difference between reality and virtual will keep decreasing to a point where you cannot distinguish what is real from what is generated from models.</p><p>Imagine a world where you could stay forever with the person you love? Or speaking to your parents, even after they pass away? Sure, many people will want this and our society is so lonely that the vast majority would love to have more company, real or <s>fake</s> virtual. There are already a few startups who are making $100k+ ARR with AI girlfriends, and it&#8217;s just a matter of time before it gets to the millions.</p><div class="subscription-widget-wrap-editor" data-attrs="{&quot;url&quot;:&quot;https://techramblings.blog/subscribe?&quot;,&quot;text&quot;:&quot;Subscribe&quot;,&quot;language&quot;:&quot;en&quot;}" data-component-name="SubscribeWidgetToDOM"><div class="subscription-widget show-subscribe"><div class="preamble"><p class="cta-caption">Thanks for reading Tech Ramblings!

came, I thought this will be helpful but will unlikely be a disruption.</p><p>I believed AI was a bubble ready to pop as blockchain or crypto.</p><p>I was an AI hater/skeptic.</p><p>I was just stupid and wrong.</p><div><hr></div><p>Actual assistant like ChatGPT desktop or Anthropic are already replacing search: I barely use Google today and ask questions directly to my phone.</p><p>Products like <a href="https://lovable.dev/">lovable</a>, <a href="https://www.cursor.com/en">cursor</a> or <a href="https://v0.dev/">v0</a> are first steps in redefining software development. I no longer use Stackoverflow and my coding questions and code refactors are done by ChatGPT.</p><p>We are just scratching the surface: AI will impact every aspect of the world as we know it: from talking to your bank to making appointments with your electrician or plumber. I am convinced it will not replace workers, it will make them more efficient.</p><p>This new wave just started and is about to go on for years. It will likely reshuffle the cards in big tech. Some products and companies will be killed, while new winners will appear.</p><p>Today, existing companies add an AI layer on top of their product (for example, Strava adding &#8220;Intelligence&#8221; to tell me that my run was faster than my average). This is a losing strategy: 90+% of the time, these AI features offer no value to the customer. They make me think of <a href="https://en.wikipedia.org/wiki/Office_Assistant">Clippy</a>: good intention, bad product.</p><p>The new winners from the AI era won&#8217;t add an AI layer on top of existing products. They will seamlessly integrate AI into existing products, making it invisible but, still, amplifying the product's core value proposition. What matters is not if you use AI, but how you use it to deliver better value to your customer.</p><p></p><div class="subscription-widget-wrap-editor" data-attrs="{&quot;url&quot;:&quot;https://techramblings.blog/subscribe?&quot;,&quot;text&quot;:&quot;Subscribe&quot;,&quot;language&quot;:&quot;en&quot;}" data-component-name="SubscribeWidgetToDOM"><div class="subscription-widget show-subscribe"><div class="preamble"><p class="cta-caption">Thanks for reading Tech Ramblings!
