Introductions Gemini 3.1 Flash-Lite 🔦, a huge step forward on the boundary of intelligence beating 2.5 Flash on many tasks. x.com/OfficialLoga...
FastAPI 0.135.0, with Server-Sent Events: fastapi.tiangolo.com/tutorial/ser... ✨
This @fastapi.tiangolo.com feature has been cooking in my mind for 2 years or so. 😅
So happy it's finally out there. And I think the developer experience is just right (minimal and simple). ✨
A few weeks ago our founder announced Monty, a minimal, secure Python interpreter written in Rust, for running code written by AI agents. People got excited. @sa.muelcolvin.com just wrote up the full story on why he's excited about it and you should be too.

Gemini 3.0 Flash + code execution is a game changer for computer vision pipelines. I just built a workflow that:
✅ Edits an image with NanoBanana 🍌
✅ Auto-creates transparent PNGs with OpenCV 🖼️
✅ Draws bounding boxes - for ~$0.006! 💸
Been a while since I did an LLM architecture post. Just stumbled upon the Arcee AI Trinity Large release + technical report released yesterday and couldn't resist :)
Also added a new section to my LLM architecture comparison article with more details: magazine.sebastianraschka.com/i/168650848/20
