Anthropic's Claude Opus 5.5 Powers Higgsfield Chess Demo as Cheaper Agentic Model Debuts

Anthropic launched Claude Opus 5.5 on September 22, positioning it as the first model in the Claude 5.5 family and a lower-cost upgrade for agentic coding, computer use and knowledge work. A Higgsfield demo showing the model building a hand-drawn-style chess game with move analysis highlights the release's pitch: frontier coding and design work at lower runtime cost.
