Anthropic's new flagship model Claude Opus 5 posts top scores in coding and knowledge work while approaching Claude Fable 5's performance at half its token rates.
Anthropic is responding to pricing pressure from GPT-5.6 Sol and Chinese competitors. Its new Opus 5 model is designed to close the price-performance gap with the much pricier Fable 5. Opus 5 becomes the default model on Claude Max and the most capable model available on Claude Pro.
The 1 million-token context window and token rates remain unchanged. Like its predecessor Opus 4.8, Opus 5 costs $5 per million input tokens and $25 per million output tokens. A new Fast Mode increases speed by 2.5x but doubles the price.
