Anthropic is reportedly readying a new model (fable 5.5) which testers says has better intuition and reasoning than any model you've ever seen (opus 5.5, sonnet 5.5 included) same week fable 5.5 reportedly reached partners and surfaced in Microsoft's catalog. coincidence? I believe fable 5.5 launch could be imminent this week. there's also talks on a Google Gemini 4 Carbon launch and a potential new Terra model from OpenAI. the frontier pace isn't slowing down
