GoKawiilAnthropic cuts prices and boosts performance with Opus 5.5 launch
Anthropic released Opus 5.5, claiming it beats its larger Fable model on many coding and knowledge benchmarks while costing 20% less per output token and running faster. The model also communicates more plainly, avoiding jargon and leading with key information. Sonnet 5.5 and Haiku 5.5 are expected to follow in coming weeks with similar gains.
