we'll be surprised how available and how weird jobs get in the future. things like *ENTROPY HUNTER* - where you investigate things like: "whats a rock taste like?" or "whats it like to not see the color blue for 2 weeks then suddenly walk into a room thats totally blue?"

@mitsuhiko Seems similar to flawless.dev, which I was following, although unclear if development on it has halted.

Absurd (next to pi) is probably the infrastructure decision that made me the happiest so far. It's so nice and easy to use. I did some updates on the docs today which were pretty atrocious before.

When one brain isn't enough, switch to Grok 4.20. Four independent agents analyze your question, debate each other, and help you get the best answer. Available now to SuperGrok and Premium+ subscribers globally.

@JaimeAlns @xai It was an absolute pleasure working alongside you Jaime, all the best with whatever comes next sir!

It’s one of those: today was my last day at @xAI. xAI has been a tremendous formative experience for me, building the API, Grok.com, and everything in between, it’s been crazy and hectic, but overall amazing. I’m especially grateful to everyone I’ve worked with, @TobyPhln and the team in London, you’re the most talented team I’ve ever worked with. I’ll be cheering from the sidelines, really excited to see what the xAI team is going to come up with next!

@TobyPhln @xai @elonmusk It's been an absolute pleasure working alongside you, thank you for your leadership Toby and all the best with whatever comes next🤝

Three years, thousands of PRs, and a million jokes. Today was my last day @xai. To the team: you rock, no one burns the midnight oil better. To @elonmusk, thanks for taking me on board. I've learnt more about execution, speed, and product perfectionism than I could ever have imagined. Thanks for everything. My next priorities: sleep for more than 8h, write down all the things I've learnt (I have a list), and then think about what I want to do next. @gork wdyt?

xAI Docs for Video and Image Generation looks Amazing

uv is now doing about 1.3 billion package installs per day, up ~40% from October

@mitsuhiko All that’s missing is an octorok that pops up intermittently

Since I got some comments on the metaballs: I had a wind waker style water shader on my blog first, but that felt cheap. But I liked it enough, that I put it on my ronacher.eu landing page :D

Grok for Education: xAI is thrilled to announce a partnership with El Salvador and @nayibbukele to bring personalized Grok tutoring to every public-school student in the country — over 1 million children. The world’s first nationwide AI tutor program. x.ai/news/el-salvad…

Introducing Grok 4.1 Fast and the xAI Agent Tools API. Grok 4.1 Fast is our best tool-calling model to date. With a 2M context window, it shines in real-world use cases like customer support and deep research. x.ai/news/grok-4-1-…

@bwjbuild @MarioNawfal We have this already - check out docs.x.ai/docs/guides/us… and docs.x.ai/docs/guides/to…

@MarioNawfal We need a RAG api like how gemini does "file search" Grok is really smart but needs application memory augmentation to work like a boss with infinite memory superpower

ELON’S GROK JUST GOT A FILE BRAIN UPDATE Grok can now read, reason, and respond straight from your uploads. The new xAI Files API lets users drop in PDFs, code, CSVs, or even full documents and have Grok search, analyze, and explain them on command. Think of it as giving your AI a filing cabinet and photographic memory in one click. It even handles multiple files at once, blending them into answers that actually make sense. Elon didn’t just build a chatbot, he built a research assistant that never sleeps or forgets. Source: @techdevnotes

@levelsio @grok If you want this behaviour programatically, you can also check out our recently launched agentic tool calling API! docs.x.ai/docs/guides/to…

This is really so useful, ask Q then ask @grok to rank the answers

@lehoho248 @xai @lehoho248 Thanks for flagging this, this should now be fixed now in the most recent version of the xAI Python SDK (v1.0.1) pypi.org/project/xai-sd…

@xai The Grok 4 live search API ignores from_time & to_time parameters in the Python SDK BUT respects them via curl. ```python from_date = datetime(2025, 7, 21) chat = client.chat.create( model="grok-4", search_parameters=SearchParameters( mode="on Jonah, max_search_results=1, return_citations=True, from_date=from_date, sources=[x_source(included_x_handles=handles_to_search)] ) ) Response citation: x.com/hubermanlab/st… # Post from Sep 24, 2025 ``` Using curl: ```bash curl api.x.ai/v1/chat/comple… \ -H "Content-Type: application/json" \ -H "Authorization: Bearer {Bearer_token}" \ -d '{ "messages": [{ "role": "user", "content": "Your mission is to help build this agent (X account) into a Key Opinion Leader, a trusted authority who shapes conversations in their niche. Quote tweets are a strategic tool for establishing thought leadership by adding unique perspectives to trending discussions." }], "search_parameters": { "mode": "on", "from_date": "2025-07-20", "max_search_results": 1, "return_citations": true, "sources": [{"type": "x", "included_x_handles": ["hubermanlab"]}] }, "model": "grok-4" }' Response citation: x.com/hubermanlab/st… # Post from Jul 21, 2025 ```

@charliermarsh Thank you to you and your team for making an amazing piece of software.

Official xAI Python SDK dropped, built on uv 💪

xAI has released a Cookbook for API Developers! "A collection of pragmatic, real-world examples guiding you from basic to advanced use of xAI's Grok APIs."

@Hesamation Ell by @wgussml looks very promising github.com/MadcowD/ell

We deserve something better than LangChain > learning it can be just as tough as a new language > there’s too much abstraction > the documentation does not cut it so what’s the best LLM framework now?
