Since I go through my github notifications on a FIFO basis, but I only keep the latest email per issue, whenever someone posts “any updates?” it moves that issue right to the bottom of the queue and I think that’s kinda poetic.

March 2026 update of The Diff & The Merge, my substack about OS maintenance. oxykodit.substack.com/p/march-2026... - free-threaded Python in FastAPI - ty as type checker - triaging nanochat PRs - nanochat's little brother "autoresearch" - publishing LLM-readable skills files

Hey if you need something to do over this long weekend, have a go at my PhD student Anna-Merete’s survey. It’s sentences to rate, you just need to have any English variety as your first language, and it’ll take you 10–15 minutes. #linguistics docs.google.com/forms/d/e/1F...

All my Python projects are now using ty for type checks 🎉 @fastapi.tiangolo.com, Typer, SQLModel, Asyncer, etc. Thank you @oxykodit.bsky.social 🙌 ty is great, try it docs.astral.sh/ty/

The Diff & The Merge: my new substack over at oxykodit.substack.com where I write about the day-to-day life of being an open-source maintainer in the Python/data/AI domain.

Here's a big one! 🎉 Official FastAPI extension for @vscode.dev 🎁 🗺️ Path operations explorer 🔎 ...and search ✅ From tests: go to definition 🎁 And more! marketplace.visualstudio.com/items?itemNa... GitHub: github.com/fastapi/fast... Thank you @savannah.dev 🙌

Somewhere along the line **someone** has to do the uncomfortable work of understanding what the hell is going on with the code and project (and keeping that understanding current in the face of ongoing changes to the project) Vibe coding is trading that understanding for short-term gains

Here's Typer 0.21.2 🎁 The highlight, @oxykodit.bsky.social added the official reference docs: typer.tiangolo.com/reference/ And updated the guide to build a Typer package to now use uv: typer.tiangolo.com/tutorial/pac...

Only 1 more day to fill the Typer developer survey! ⌨️ The results will guide future features and (breaking) changes. 🔥 forms.gle/XEH3NL2wqpFP...

If you're using Typer, please fill in this survey to help us drive future developments in line with what the community needs! 🙏

Here's SQLModel 0.0.32, fix support for Annotated fields with @pydantic.dev 2.12+ 🐛 Thanks @vimota.bsky.social ! 🙌 And thanks @patrick.wtf , @oxykodit.bsky.social , and YuriiMotov for the work and help. 🍰 sqlmodel.tiangolo.com

This "Automated Contributions Policy" from scikit-learn is really good and on point: scikit-learn.org/dev/develope... Please, whatever OS repo you intend to contribute to, read this first 🙏

I just migrated the docs for Asyncer from Material for MkDocs to @zensical.org ✨ I was expecting a challenge, I was disappointed, it was too easy. 😂 Install and run, that's it. All the configs unchanged, even the CLI preserves the exact same commands. ☕️ asyncer.tiangolo.com

You didn't hear it from me! 🤫

Awesome team! 🫶

I've always wanted this, a Github action that flags PRs that received a merge conflict due to a recent merge into master/main. Yay! More merge conflicts to resolve! Fun times ahead!

Here's a quick bug fix Typer release, 0.16.1 🐛 Thanks @oxykodit.bsky.social! 🙌 github.com/fastapi/typer

One of the most underrated players in AI models, IBM, released 2 new extremely efficient embedding models: granite-embedding-english-r2 & granite-embedding-small-english-r2, commercially viable. Details in 🧵:

How can we better understand how models make predictions and which components of a training dataset are shaping their behaviors? In April we introduced OLMoTrace, a feature that lets you trace the outputs of language models back to their full training data in real time. 🧵

ChatGPT telling me it's giving me a **curated** list is giving me the creeps.

Here's FastAPI 0.115.14 🚀 @patrick.wtf fixed support for unions of @pydantic.dev models in Form data. 🐛🎉 (This will make it easier to implement single sign-on 😉) github.com/fastapi/fast...

Here's FastAPI 0.115.13 with a bunch of bug fixes and tweaks 🎁 Special thanks to Yurii for all the work handling discussions and PRs! 🙌 github.com/fastapi/fast...

We’ve just made it even easier to build with our open models and datasets ✨ What’s in our docs platform? ⚙️ Setup instructions 🚀 Hosting + deployment ⭐ Integration examples ⚡ Optimization tips

Data doesn't lie, but it can mislead! At PyCon Italia 2025, I gave a keynote about how to ensure integrity of your ML applications by inspecting your data, developing good baselines and interpreting your performance numbers. Slides: speakerdeck.com/sofievl/2025... Video: youtu.be/qXx-4m-Z0q4?...

Looking forward to presenting my keynote tomorrow at PyCon Italia. If you're into data and/or Formula One, come join at 5PM ! @pyconit.bsky.social

I’ll give a talk about @pydantic.dev AI and Logfire today 12:25 at @pyconit.bsky.social 🙏

Every now again it’s useful to repeat advice about accessing papers that are behind a paywall that excludes you. Email the author. My estimate is that 90% of academics are so thrilled that a living, breathing, possibly even reading, person shows interest that they will swiftly send you a copy.

Here's a Typer release for you: 0.15.3 🥟 This has a couple of bug fixes by @oxykodit.bsky.social 🙌 github.com/fastapi/typer

At PyCon Italy, I'll be talking about a topic close to my heart: data quality and how your data modeling decisions impact your downstream AI/ML/NLP applications 🕵️

Hoping to see many of you Italy!

It is *so critically important* that unit tests be *completely understood* by the person writing them. That is your safety net! That is the foundation upon which the rest of your code is built! Let copilot generate all of your code as long as you write the unit tests! 😭

This blog post will hit its 25th birthday in about a week. 25 years, folks. That's enough time for pretty much everybody to have read it www.joelonsoftware.com/2000/04/06/t...

Up to 5/15 top models in ChatBotArena being open weights. Yes, there are caveats as always, but this is THE BEST opportunity people have ever had to build things on open models. R1, Gemma 3, DeepSeek V3, QwQ, Command A 🫡 www.interconnects.ai/p/gemma-3-ol...

You thought I was joking? I'm not, come and work with me, for real. It's potentially fun and loaded with emojis. 😅 If you like FastAPI and know a lot about Kubernetes, cloud, observability, all that stuff, send an email. And send this to your badass SRE/DevOps friend. 🚀

Now I'm looking for someone with 7+ years of FastAPI experience 🤭 Jokes aside, I'm doing interesting new things and want some extra help full-time 🚀 I'm looking for tons of skills and knowledge in SRE / DevOps / Platform / Cloud / name-it ...and of course, FastAPI Email [email protected]

Some tips on prompting the new Gemma 3 models, instruction tuned. At the Google Gemma Day research release.

Super excited to start cooking with the newly released open-weights Gemma 3 models and their long context window 🤩 So exciting to be in Paris at the launch today! #LLM #gemma #ai #developers
