But it still surprises me how well it performs and how close it is to other frontier models on toughest challenges. https://t.co/p7mKtDuj3f pic.twitter.com/TiQLRI5EHd
Didn't expect Meta's model to outperform Opus 4.6 or GPT-5.4. But it still surprises me how well it performs and how close it is to other frontier models on toughest challenges. Epoch AI (@EpochAIResearch) We had pre-release access to Meta’s new Muse Spark model and evaluated it on FrontierMath. It scored 39% on Tiers 1-3 and 15% on Tier 4. This is competitive with several recent frontier models, though behind GPT-5.4. — https://nitter.net/EpochAIResearch/status/2041947954202988757#m
