Excited to connect with a bunch of you at connect! @claireszhou and I are going to see a bunch of you at the roundtable and don’t forget to tune in for the Developer SOTU for @vishalshahis and yours truly. Meta.com/connect
It’s #MetaConnect2026 week! ♾️ Very excited to be a part of this year’s program speaking on Muse Code. It’s only been a few hours, but I’ve already had a fantastic time connecting with our developer community on agentic coding workflows and the future of building with @Meta products. Tune in to the livestream at meta.com/connect/ Things I highly recommend watching - Mark’s keynote - Developer State of the Union - Build and deploy with Muse Spark (Muse Code & Model API) I’ll be at the AI Developer Roundtable with @pratanchandani tomorrow - can’t wait to see you there!!

Computer use has been a key area of capability development across the coding, agents, and multimodal post-training work at Meta. Life for many of us extends beyond the browser. Computer use via @Muse takes your personal agent one step beyond the browser use that many have already seen in action, granting it access to your local machine to push the boundaries of what it can accomplish for you!! This means easier access for working with PDFs and other documents, sorting through all your old photo albums, engaging with desktop apps, and so much more.
Muse on Mac can now take over your computer and do things for you! Local computer use has shipped at Connect! 🥳 This is what I worked on at my startup 2 years ago with many great folks before joining Meta. Very excited to see it now shipped for the masses!

FYI, I am not sponsored by meta at all. I just really love cool stuff … and sadly most of the ai products we have right know are seriously uncool. This is because they are built by people who aren’t cool in the first place, it’s just engineers building for other engineers who think the whole world is made of code and everything runs in a terminal. Apple was the most valuable company on earth for over a decade because of one simple reason. ANYONE could pick up an iPhone and use it and get value out of it, from young kids to grandmothers. You don’t have the equivalent of that today in AI, we just have a bunch of nerds with psychosis and early signs of schizophrenia who would rather talk down to their users and tell them AI is too dangerous and is going to kill everyone… that’s not grandma friendly. I think people forget that technology and knowledge by extension is the great equalizer. Many will try to gate keep this stuff but I give kudos to meta for actually innovating in this domain and making a product anyone can use while still being fun and friendly! Muse is 1,000x more valuable and important than just another coding model with a 2% eval bump that everyone will pretend is great and will just be used to write unit tests. The bottleneck was never the model it was the fact that you have no taste, no agency, and for that reason you don’t build anything impactful. You know what’s really impactful? An agent that is personalized to me, that gets my jokes, knows my taste, has my swag. A thing that knows me inside and out is worth a hundred times more than a thing that knows everything else but that and always talks down to me. This should be a stark warning to all the AI labs, you risk alienating your users more by patronizing them and limiting their experience. There is only so much coding market share left and what comes after that is just ten times harder and more difficult to monetize instead of just doing good for your users. Good luck 👍 & shout out Meta for really delivering a game changing experience !

Excited to share that the Muse Code Python SDK is live today!! 🎉🎉 Use it via pip install muse-code-sdk Details at pypi.org/project/muse-code-s…
Muse Code is now an import away. muse-code-sdk is an asyncio-first Python client for Muse Code sessions: spawn or attach, stream a turn, handle tool approvals, resume later. pip install muse-code-sdk pypi.org/project/muse-code-s…

i actually didn't realize this until seeing this post, but muse spark 1.3 ranks as #2 on Agents Last Exam (ALE)!
Muse Spark 1.3 ranks #2 on Agents' Last Exam (ALE) leaderboard, ranked #1 at the time of its release. Kudos to the team! Somehow this didn't get enough buzz. Leaderboard: agents-last-exam.org/leaderb…

We just added Muse Spark 1.3 on MathArena! A solid overall performance on ArXivMath, nestling itself in the top 5 at a low cost.

One of the best surprises of joining MSL/TBD was meeting people I had never heard of but who were *brilliant* Joel Pobar is one such person. Every essay of his I read was 6-12+ months beyond my own thinking His LLMVM harness (started in mid 2023!) is a great example 1/3
am I now allowed to say RLMs are a rebrand of Joel Pobar's LLMVM ?

RSI is not a binary event, it is a continuum of compounding loops -- and we are already in the continuum.
Introducing Gemini 3.8, our best reasoning & coding model yet. By leveraging long-running agentic loops, we’re building on the momentum of 3.7 Flash from just three weeks ago to release two new 3.8 variants: Meet Gemini 3.8 Flash and Gemini 3.8 Flash Cyber 🧵

made muse amazing for home automation
Muse is the first agent from a large company with Tailscale support. Meta—the consumer company—added Tailscale support!1!! Can you imagine how much corporate BS the team had to bulldoze through to override the logical choice and just do the fun thing for tinkerers?

A cool thing about @Muse is that every Muse runs on its own Linux machine. So you and your Muse can do normal Linux stuff together — like build your own terminal!
