Exciting news: Muse Spark 1.2 (xHigh) by @AIatMeta is #4# in the Text Arena (1498 pts), and has reshaped the Pareto frontier! It is priced at $1.25/$4.25 per MToken. Congrats again to the @AIatMeta team on this release!

Muse Spark 1.2 places Meta on the Cost per Task Pareto frontier, scoring 6 points below Claude Opus 5 at ~1/6th of the cost At Meta's $1.25/$4.25 per 1M token pricing, Muse Spark 1.2 (xhigh) sits on the Pareto frontier of Intelligence Index vs Cost per Task. It delivers comparable intelligence to Claude Opus 4.8 (max, $2.03) at a fifth of the cost per task, and undercuts GPT-5.6 Sol (high, $0.55), GPT-5.6 Terra (max, $0.61), and Kimi K3 (max, $0.87). The nearest cheaper options are Grok 4.5 (high, $0.36) and GPT-5.6 Sol (medium, $0.37), and they all sit below it on the Index. The step up from Muse Spark 1.1 ($0.29 per task) comes at unchanged per-token pricing, with the increase driven by heavier token usage on agentic tasks.

American companies should not be selling data to Chinese AI labs. @scale_AI doesn’t do this work, and we have turned down revenue because of it. The companies that do are undermining American AI leadership and risking national security.

To understand whether we're making genuine progress on reasoning, we entered our AI models in five international STEM Olympiad competitions this year. The results: 🏅 Asian Physics Olympiad (APhO): Perfect score on the theory exam — gold medal 🏅 International Physics Olympiad (IPhO): Perfect score on the theory exam — gold medal 🥇 International Mathematical Olympiad (IMO): Gold medal, top 4% of human participants 🥇 International Chemistry Olympiad (IChO): Gold-medal level performance 🥇 Romanian Masters of Mathematics (RMM): Gold-medal level performance Three of these (APhO, IPhO, IMO) were live competitions and our solutions were submitted under real competition conditions and graded by the official judges using the same marking criteria applied to student contestants. A few things about the approach: • Models were internally trained versions from the Muse Spark family • Zero tool use: no search, no code interpreter, no calculator • Multi-agent orchestration with parallel reasoning We are excited about where this reasoning capability goes next; frontier research level across scientific domains and personal superintelligence. Super grateful to the organizing committees of APhO, IPhO, and IMO for supporting our live participation. We have deep respect for the contestants and organizers behind these competitions. 🙏 And proud of the MSL team that pulled this together!

The results: 🏅 Asian Physics Olympiad (APhO): Perfect score, theory exam 🏅 International Physics Olympiad (IPhO): Perfect score, theory exam 🥇 International Mathematical Olympiad (IMO): Gold medal 🥇 International Chemistry Olympiad (IChO): Gold-medal-level performance 🥇 Romanian Masters of Mathematics (RMM): Gold-medal-level performance The types of problems in the Olympiad competitions are exceptionally hard, demanding deep chains of reasoning, creative insight, and flawless argumentation. To test pure reasoning capability, we disallowed all tool use, meaning no search, no coding, and no calculator. We have deep admiration for the contestants and committees behind these competitions, and are grateful for their support in enabling our participation.

When I heard some time ago that Meta is the third best AI lab right now, I was skeptical. But every day passing has been reinforcing that it’s actually true. TBD strategy has succeeded and congratulations to the team that made it! The world needs more successful AI labs

One of the things the pelican benchmark is still useful for is visually representing (to a tiny extent) the improvements in a single model family Here's Meta AI's Spark (8th April), Spark 1.1 (9th July), and Spark 1.2 (today, 5th August)

I'm impressed by muse so far! Interesting how of the 10 bundled skills, one is `taste`, a list of "what NOT to do," including: - cream backgrounds - gradient text, purple accents - an "8+ word 48px+ heading that says nothing" lol
