What happens internally after an OpenAI endpoint receives a user prompt? I wasn't comfortable with treating AI models as magical black boxes, so I made some sequence diagrams that I'm sharing with you in this post: milendyankov.com/blog/2026/04...

We used to glorify the app servers? The WebSpheres, WebLogics, JBosses, Zopes, Zends, ... We’re doing it again with LLMs. IMHO "doing one thing well" phase is next, so I'm coining a term now - μAI (Micro-Intelligence) Remember you heard it here first when it becomes viral in a few years 😜

The "Anatomy of a Model - the Developer Perspective" blog post from the "AI for Application Developers" series took longer to write and went way beyond my notes. But it was fun, and I even learned new things. I hope you will, too. milendyankov.com/blog/2026/03... #AIforDevs

A thought of the day: Did AI kill DRY 🤔?

Wrote sort of a tiny survival guide for the AI model formats jungle. If you are looking to run AI/ML models locally or just curious how they are distributed, have a read and let me know if it helps. milendyankov.com/blog/2026/03...

Entering the AI world, I expected a familiar landscape of libraries and APIs. I found "serialized Python" and a massive gap between my code and the math. Let me save you some disappointments if you are on the same track: milendyankov.com/blog/2026/03...

AI is currently polarized between academic math and "Look ma!" demos. I feel that we, the app developers, lack the middle ground. We need to understand the abstraction layers below the magical API calls. I’ll be sharing my notes on the subject as blog posts: milendyankov.com/blog/2026/03...

Never ever in my decades-long career have I been so frustrated by the phrase 'You are absolutely right".

I've spent years in companies calling themselves startups. It took me a while to realize the label doesn't imply sameness. It took me even longer to self-diagnose the career friction I experienced. The recent Tailwind story triggered me to write something about it: milendyankov.com/blog/2026/01...

Somehow, revamping my personal website felt awfully similar to designing enterprise software systems. Different scale, same existential dread over choosing the wrong framework. If you find yourself constantly asking "Am I doing this right?", this may help (or not): milendyankov.com/blog/2025/01...

Do you remember this viral video from about a decade ago? 👉 www.youtube.com/watch?v=cDA3... It was satire, not a design spec for AI agents.

For me, AI solves one of the two hardest problems in software development - naming things. It still can't really help much with cache invalidation and off-by-one errors 😜

Catch Milen Dyankov's insightful session "AI for Java Developers - From Buzzword to Code" at #devbcn25! He'll dive deep into practical AI applications in Java - don't miss this chance to level up your skills. Check out the session recording: buff.ly/dNQRU2B #DevBcn

Curious how to start using #AI models from your #Java code? If you have an hour, here is the recording of my "AI for Java developers" talk at @devbcn.bsky.social youtu.be/UjBUHdfUjVM?... Let me know if it was helpful.

Once, only elites could read and write—they were the writers. Literacy spread, but few became authors. Writing well still takes skill and craft. Software dev was once for specialists. Now, no-code lets almost anyone “write code.” But just like literacy, producing code doesn’t make you a developer.

I was really worried my talk is too basic for #devbcn25 Imagine my surprise when I saw the reviews. Thank you everyone who attended!

The only session I could attend (partially) is the one by @milendyankov.com and I have to say that I liked it very much ! Very well explained, all the concepts related to #AI, the models behind it, what are #LLM's, @ollama @langchain4j, ... bravo! 👏 🙂

I can literally listen to @brianvermeer.nl all day long without ever getting bored.

From AI hype to hands-on code! @milendyankov will walk Java developers through real use cases in his #devbcn25 session: AI for Java Developers – From Buzzword to Code. Join us July 8–10 in Barcelona! Details 👉 buff.ly/YpnATm9

Would you go for 2.10 or 2.9 when you need the latest version of a library/app? Asking for my math teacher 😉

A good #VectorDB is a must-have for AI-powered solutions on top of massive datasets. But that doesn’t mean this is an experts-only territory. With the right tools and guidance, even newcomers can use #RAG and add genuinely useful #AI to their projects. www.youtube.com/watch?v=OSB0...

This is where I'll present "AI for Java developers" tomorrow. Today @piotrprz.bsky.social rocks the @jprimeconf.bsky.social scene!

Hey folks, just wanted to let you know we have a few open roles at Pinecone – specifically for Senior/Staff Software Engineers and a Support Engineer. If you or someone you know is looking for a new opportunity, check them out: www.pinecone.io/careers/?utm...

I’ve been exploring the land of MCP servers recently. Meanwhile, my colleagues at Pinecone have been building the first official ones for Pinecone’s Database and Assistant. Now that they’re out, I wrote a blog about what those MCP servers are and how to use them: www.pinecone.io/blog/first-M...

The emerging vibe coding field has come up with a new productivity metric: kilos of code 😜

So should we now stop using terms like "self-driving" or "autonomous" cars and start talking about "vibe driving" instead? Asking for a friend.

It's heartwarming to get such a comment under a 3-year-old blog post

The time has come to start a new chapter in my career. I'm joining Pinecone.io as a Staff Developer Advocate to contribute to their mission of making AI knowledgeable. Wish me luck in this endeavor.

Somehow I only recently discovered the `group(...)` and `groupCollapsed(...)` methods in the Console API. Combined with esbuild's ability to remove all `log(...)` and `debug(...)` from production builds, logging to the browser's console while developing JS/TS apps is a whole new experience.

The only part of this article which is even remotely implausible is the bit at the top where it says it’s “humor”… yes, it’s laugh-out-loud funny, but only because it’s horribly, excruciatingly accurate.

After seeing some impressive recommendations, I decided to join Bluesky. Hopefully, the experience will be better than my previous attempt with Mastodon ;)
