Meta Releases Muse Spark 1.2 AI Model
Zuckerberg posted that the new model advances Meta toward larger frontier systems with added audit logging.
Mark Zuckerberg stated that Muse Spark 1.2 is the next step toward larger frontier models. He described it as auditable by design, with every model call, tool run, and edit recorded in a local event log that allows recovery from crashes without re-prompting. Separate posts noted a 3-point gain on the Artificial Analysis Intelligence Index to 54, concentrated in agentic tasks such as GDPval-AA v2, Terminal-Bench 2.1, and Tau3-Bench Banking. One reply placed the model on the Pareto frontier at $0.40 per task.
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.

41 postsAuditable by design. Every model call, tool run, and edit hits a local event log before it executes. If it crashes mid-task, it picks up exactly where it left off from that log. No lost work and no re-prompting.
Muse Spark 1.2 is our next step as we push toward frontier, with larger, more capable models on the way. Install it, use it, tell us what you think.
On Agents, we also see substantial improvements on GDPVal and MCP Atlas.
it's a well priced model, sir... and now available globally!
Pricing: It's easy and low-cost to get started. Install Muse Code with one line and you can start on our contributor tier.
@xeophon they should make it free or release it
🚨 Meta Muse 1.2 just launched they are moving quick and i loved this output from this model if they move like this and maintain the cheap price and then no one can stop meta's comeback
