Quick Typer release 0.18.0 (and 0.17.5) with compatibility for the latest Click just released 🐛 Thank you @oxykodit.bsky.social for the fast discovery, analysis, and fix! 🙌 github.com/fastapi/typer

Quick Typer bugfix release, 0.17.4 🐛 Thanks @oxykodit.bsky.social! 🙌 github.com/fastapi/typer

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

move slowly and build things

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

I'll be in Paris for the next two days, attending Google's Gemma Developer Day. Hoping to catch some interesting talks and people! #google #gemma #llm #ai #opensource

Here's SQLModel 0.0.24 with support for Python 3.13 🐍🚀 This is the last release to support Python 3.7 and Python 3.8 🧟 ...should have dropped support for them a while ago 😅 The backwards compat took a LOT of effort from @oxykodit.bsky.social, thank you! 🙌 github.com/fastapi/sqlm...

I have a couple of tricks I use with my open source projects, starting with @fastapi.tiangolo.com 🤓 Someone once called it "documentation driven development" 📝 If you're curious, here's the short tale of a bug that shows that 🐛👇️

Huge shoutout to colleagues at Google & Unbabel for extending our WMT24 testset to 55 languages in four domains, this is game changer! 🚀 I really hope it puts the final nail in the coffin of FLORES or WMT14. The field is evolving, legacy testsets can't show your progress arxiv.org/abs/2502.124...

New SQLModel 0.0.23 with a couple of bug fixes 🐛 Thank you @oxykodit.bsky.social for all the help! 🙌 github.com/fastapi/sqlm...

A great TED talk by Thomas Wolf about how open-source and open-weight models contribute to resiliency of applications and the AI eco-system in general 🚀

Small Typer release, 0.15.2, with a couple of bug fixes, including completion for Fish shell ⌨️ Special thanks to @oxykodit.bsky.social, she has been key to the project! 🙌 github.com/fastapi/typer

Did you use the full-stack @fastapi.tiangolo.com template to build a project or product? ✨ Share it in this GitHub Discussion! 🤩 github.com/fastapi/full...

All of this, so much - but it certainly requires a shift in thinking/planning.

The answer was not the point. The answer was never the point. The process of searching is the process of learning.

Just published part 3 of my blog post series on making beautiful slides for your talks 🎨✨ This one is about presenting technical content and making dry & abstract topics more interesting. Featuring many examples, including talks by Vitaly Meursault & @oxykodit.bsky.social! ines.io/blog/beautif...

Here is Tülu 3 405B 🐫 our open-source post-training model that surpasses the performance of DeepSeek-V3! It demonstrates that our recipe, which includes RVLR scales to 405B - with performance on par with GPT-4o, & surpassing prior open-weight post-trained models of the same size including Llama 3.1.

These past days @fastapi.tiangolo.com surpassed Laravel (PHP) and Gin (Go) in GitHub stars 🤩 Python has the two most starred web backend frameworks in all languages: Django and FastAPI 🐍🚀 github.com/fastapi/fast...

Happy year of the Snake, everyone! 🐍🎉

If you want to quickly catch up on all the open modeling things (DeepSeek, ModernBERT, etc.), this was a great overview, by @natolambert.bsky.social. I somehow got into an argument last week with someone who was insisting that all models are industrial blackboxes... and I wish I'd had this on hand.

I just released Sentence Transformers v3.4.0, featuring a memory leak fix (memory not being cleared upon model & trainer deletion), compatibility between the powerful Cached... losses and the Matryoshka loss modifier, and a bunch of fixes & small features. Details in 🧵

You shouldn't be doom scrolling but in case you are here's your hydration reminder

The small joy of being able to replicate a user's bug and finally having a path to debugging 🚀 The small wins in life. Now to actually go and squash the 🐛!

Smol-scale vector search doesn't need a dedicated vector database! You can simply use the Hugging Face Hub. code: https://buff.ly/4jfilpC build on DuckDB: https://buff.ly/4jgWAWl

My video on spaCy layout is now out! This is probably my favorite update from @explosion-ai.bsky.social (and that's saying something!) This package makes it simple to do region detection, table detection, and OCR with just 1 line of Python. Video: youtu.be/quJtzVxoMtE #MachineLearning

So I've now finally bought a split keyboard and my right index finger is consistently hitting an empty space when I want a B. It's slowly starting to adapt to hit the N instead, when we still want a B. How's your Wednesday going?

I often think back about this comment a fellow Computer Science student made back in our first year at uni, during a linear algebra class. "When would we ever use these matrix multiplications in real life anyway" Oh sweet summer child 🥲
