Anthropic released Claude Fable 5.2 and Claude Mythos 5.2, offering the same underlying model with two distinct safeguard configurations. Fable 5.2 scores 49.1 percent on FrontierCode 2.0 and carries a 1M-token context window at pricing of $8/$40 per million tokens (MarkTechPost). On the Remote Labor Index, Fable 5.2 completes 41.3 percent of real freelance jobs at professional quality, more than double the next-best systems Opus 5.5 and GPT 6 Astra, up from a top score of 2.5 percent a year ago (The Decoder). Google DeepMind released AlphaProof Code, with agents writing three million lines of proofs in Lean to verify Signal’s core encryption (Google DeepMind).
Meta introduced Muse Ember, a small model designed for repetitive agent work including tool calls, routing, and data extraction, with a 1M-token context window. It ties Claude Haiku 5.5 on the Artificial Analysis Intelligence Index at roughly a third of the cost per task (MarkTechPost). Adobe launched agentic AI features across Photoshop, Premiere, and Firefly, including a new prototype builder tool in Firefly (TechCrunch).
