I usually read docs when learning a new technology, and @FastAPI has one of the most comprehensible docs.

@gauthampai You had to do everything by hand, now it's as easy as it could be. 🤓

@FastAPI Are you telling me there was no SSE in FastAPI all this while? I recently vibe coded a prototype using Codex and asked it to implement SSE in a FastAPI based app. Need to see how it has done it. 🤨

Fawad! Just pushed FastAPI to its limits with 1,000 concurrent mixed-speed clients on our production-grade stack. Results are solid: 100% success rate with zero dropped connections. Even with 50% slow clients (simulating high backpressure), async handled it perfectly. Zero RAM spikes observed—buffering is truly a thing of the past. It’s rock solid under heavy p95 load

FastAPI 0.134.0 is fire! 🚀 Streaming thousands of items via the new JSON streaming feature has made our inventory system faster than ever. Stable RAM and low latency thanks to Pydantic's Rust core. Kudos to @tiangolo @FastAPI 🔥

Build APIs, use @FastAPI
Jessie Frazelle@jessfraz
for like 10+ years, I've been like everything needs an API, I won't use tools without an API, we dont buy tools without now all of a sudden you all get it and are saying the same because AI is your 10x dev ya I had this power and wanted this before all you, welcome to the club

FastAPI 0.133.1 comes with the official FastAPI Agent Skill bundled 📦️
More important than the current skill content is that it will be kept up to date with new versions of FastAPI 😎
AI coding agents will be able to use best practices and new features as they come 🤖

FastAPI 0.132.0 adds strict Content-Type checking for JSON requests 🏰
This would solve a CSRF risk in local-network apps (apps intended to run on users' machines, on localhost) 🔒️
If your clients don't send a Content-Type, you can also disable it: fastapi.tiangolo.com/advanced/stric…

@sarthak_singh2 @pydantic Faster, in fact, ORJSONResponse and UJSONResponse are now deprecated. 🔥

Increase your FastAPI JSON response performance by 2x or more 🚄
1. Upgrade to the just released FastAPI 0.131.0 🎁
2. Declare your response model - return type ✨
With that, now @pydantic handles the JSON serialization on the Rust side 🦀

Amazing update! 🚀 Since we are already using response_model across all our API routes, the transition to 0.131.0 immediately activated Pydantic’s Rust engine. We’ve seen an incredible drop in loading times on our admin panels, where hundreds of products are listed. Great work, team!

1. Upgrade to FastAPI 0.131.0
2. Declare a return type (response model)
3. Profit ✨
(Maybe not "profit", but better performance for sure 🤷)
Navneet@navneet_rabdiya
@FastAPI @pydantic just benchmarked this - the Rust-based serialization in 0.131.0 cut our p99 from 89ms to 41ms on a response payload with nested arrays if you're not declaring response models you're missing the biggest perf win in recent FastAPI releases

🐛 Here's FastAPI 0.129.1 with a bug fix in the JSON Schema for binary data and file uploads.
