San Francisco
Claude family. Leads measured intelligence and repository coding; premium pricing, strong computer-use and writing.
www.anthropic.comAnthropic’s limited-access peak. Tops composite boards, but you cannot buy it on the public API. Treat Fable 5 as the available twin.
Highest generally-available Intelligence Index. Half of Fable’s price, first-choice for agents and knowledge work.
The available Claude that wins the hardest coding evals. Expensive and slower than Opus 5. Default when the repo is the product.
Last-gen Opus at current Opus 5 prices. Keep it only if a harness is pinned; otherwise move to Opus 5.
Anthropic’s daily driver. Not the crown, but the one you actually leave on in production if Opus is too rich.
High GPQA, lower agentic score than 4.8 and 5. A snapshot, not a destination.
Anthropic’s fast cheap tier. Useful for classification and routing, not for the frontier jobs on this board.
