Anthropic released Opus 5.5, a new model that outperforms the larger Fable model on many benchmarks and is cheaper than its predecessor, with output tokens priced at $20 per mTok versus $25 for the previous model.
- The model is also faster and less prone to jargon.
- Anthropic stated that Sonnet 5.5 and Haiku 5.5 will follow in the coming weeks.
