Muse Spark 1.3 is rolling out today with frontier performance almost too cheap to meter. This is the biggest jump we've made so far on coding and agentic work. Try it in Muse Code and our API. Next up 🍉 and Muse Spark open weights releases coming soon. https://t.co/XQQEDEJGD7

Releasing Muse Code in beta today. It's a terminal coding agent that takes on complete software engineering tasks across large repos: planning changes, writing code, validating the results. Powered by Muse Spark 1.2, a coding-focused model update. https://t.co/xqavk41w6v

Muse Code is out of beta and now built to handle bigger, more complex engineering tasks. Developers can get started with one command today: curl -fsSL https://t.co/0RApZrEJMv | bash

Muse Spark 1.3 from Meta is now available in Cursor! https://t.co/jgT8OtOLfO

I had Muse Code convert a TanStack version of our new site to Astro. It did a flawless job. And all I managed to spend was 20 cents!! I think maybe this token stash from @finkd and @AIatMeta is going to last longer than the sun has gas left to shine 🌅 https://t.co/P0ruXB8Vlq

1/ we just publicly released Muse Spark 1.3 max! we see significantly stronger coding and agentic performance on muse spark 1.3 max, so would strongly recommend trying it out even if you've already tried muse spark 1.3 high or muse spark 1.3 xhigh. https://t.co/U5PvZ8CiN1

CodexBar learned a few new tricks in the last few weeks! TypeSafe, Nous Portal, Muse Code, CodeRabbit, Replicate, HuggingFace, Pi, Helmcode, v0, Charm Hyper, GitKraken AI, Bifrost My ambitions for this app REALLY outgrew the app name. (Oh and these keychain alerts are no more)

We tried using Meta's new Muse Code agent, but it has a bug that doesn't let it sign in from a docker container. So we did a fun experiment: Meta claims Muse Spark 1.2 was co-trained with their Muse agent harness. So we extracted instructions from their system prompt and added https://t.co/zhxsezv6gs

Muse Spark 1.3 is now available in Muse Code and Meta Model API. It’s tuned for the agentic builds developers actually ship, including long-running, multi-agent workflows. 🧵👇(1/4) https://t.co/aS8cuVgMuU

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! https://t.co/aDy4pLVyrs

Meta’s Muse Spark 1.3 Contributor model is now available for free in Cline. Benchmarks show it’s similar in performance to Opus 5, but considerably more affordable. https://t.co/AZisU1VHls
OpenRouter@OpenRouter · 21 Aug
We’re excited to bring @AIatMeta’s Muse Spark 1.2 contributor tier to OpenRouter. At $0.10/M input and $0.20/M output, It’s meaningfully cheaper than Muse Spark 1.2 and beats other comparable models on real cost, providing frontier intelligence-per-dollar. https://t.co/YNf6EprqiW

Muse Spark 1.3 is now available on OpenRouter! Built for long-running agentic, multi-agent, and coding workflows. It tracks what it learns, handles conflicting inputs, and asks for clarification or confirmation when needed. Use it now: https://t.co/vKNEn6KtVD
OpenRouter@OpenRouter · 5 Aug
Muse Spark 1.2 from @AIatMeta is live on OpenRouter alongside expanded global access to both Muse Spark models. At $1.25/M in and $4.25/M out, the model builds its position as one of the most price-efficient, high-intelligence models on OpenRouter. https://t.co/1bUqsybnmD
Mark Zuckerberg@finkd · 31 Aug
Workflows can break out a task across multiple focused agents, carry the intermediate work between stages, and return one result at the end. Good for engineering work that's too complex for a single agent. https://t.co/uEEB4TzWgL
Mark Zuckerberg@finkd · 31 Aug
There's an SDK in developer preview for building your own agents on Muse Code. Embed them in your apps, connect custom tools, stream progress, and resume sessions later.

Ollama already support the Muse Code harness out of the box? You can try it with models via Ollama (local and cloud): ollama launch muse

For funsies, I got Claude Code running on my Muse agent’s computer tonight. Muse gives every agent a Linux VM with 2 vCPUs, ~8GB RAM, 100GB of persistent disk plus a scheduler, hosted artifacts and their permission system. The VM has no inbound ports, so I built a tiny https://t.co/ZmTFUXHh1I

AI developers - we’ve published a technical guide covering how to get started with Muse Spark on Meta Model API. Muse Spark is a multimodal reasoning model built for agentic tasks, coding, computer use and long-context workflows. See what you can build 👉 https://t.co/d3raFYsyxp https://t.co/XkQqgGB9CF

Tips for 🥽 VR/MR developers, or anyone getting into VR by building a new app or game: leverage the Meta VR CLI + Muse Code in your agentic workflow. - An MCP server that gives your AI coding agent full context from the Meta VR docs - Device management: list, inspect, and https://t.co/OSzYm2o7dU

I pay for @Muse Code but didn't want to live in a terminal. On Windows it's WSL-only. So I built Helicon: an open-source desktop app for the actual Muse CLI. • uses your existing muse login, no API key • talks to muse serve over MSP, so Muse stays the agent • resumes https://t.co/6KQJIndiqr
DHH@dhh · 6 Sept
Got muse cli hooked up for both default agent action and lazy-loading. Come give it a try, @finkd 🙏 https://t.co/VOPInLga7S
Dilmer@Dilmerv · 18 Sept
Just tried something new with Muse and Meta VR CLI 🤯, and it’s insane that this works! But it makes sense because we’re literally getting a VM with our agent. I told the agent to install Meta VR CLI and use it to search our developer docs going forward. This is huge for VR/MR https://t.co/OySKrPXDkO
