Anthropic Debuts Opus 5 at Half the Price of Its Fable Sibling
Anthropic says Opus 5 matches near-frontier performance at half the price, with lower token costs, stronger coding results and an automated API fallback.
- On Friday, Anthropic released Claude Opus 5, claiming it "comes close to the frontier intelligence of Claude Fable 5 at half the price."
- The model costs $5 per million input tokens and $25 per million output tokens, matching Opus 4.8 pricing while offering improved agentic coding and computer use capabilities.
- Anthropic removed 80 percent of the system prompt for its latest models, with engineer Thariq Shihipar noting users may need to simplify prompts to optimize performance.
- The API now includes an automated fallback function routing requests deemed too dangerous to a less capable model instead of blocking them outright.
- Leading the Artificial Analysis Intelligence Index with a score of 61, Opus 5 is now the default model on Claude Max and Claude Pro subscription plans.
