As of October 20, 2026, Anthropic Claude Sonnet 4.5 ranks #97 of 213 models overall with 20.7 on the Artificial Analysis Intelligence Index. Its strongest category is knowledge, where it ranks #27 of 147. Anthropic Claude Sonnet 4.5 costs $3.00 per million input tokens and $15.00 per million output tokens. It was released on September 29, 2025.
Its output price ranks 315 of 349 priced models, counting from the cheapest.
Claude Sonnet 4.5 is Anthropic’s most advanced Sonnet model to date, optimized for real-world agents and coding workflows. It delivers state-of-the-art performance on coding benchmarks such as SWE-bench Verified, with...
anthropic/claude-sonnet-4.5 The tick on a coding bar is the median of every model measured on it. Outside coding, the place is this model's rank on that board. A board that never ran the model says so.
Measured in 6 of 6 categories. A place counts only the models measured on that board.
The index averages only the coding benchmarks that have a result; the others are skipped, never filled in. How it is weighted

A list price says what a token costs. The cost per solved task says what a working answer costs, which is the number that decides.
Beside a result, many boards publish what the run cost, how long it took, the tokens it spent or the votes behind a rating. Each figure as its board printed it, one board per row.
