Anthropic's first model in their new Claude 5.5 family
Claude Opus 5.5 is Anthropic’s latest model for agentic coding and knowledge work, delivering major performance gains, clearer communication, stronger safety, and 40% lower cost than Opus 5 on typical workloads.
Scored deterministically. Only candidates that fire a story trigger are sent to a model, so this one has no written angle.
Gaps in our data, not findings about the product. Their weight is redistributed across the 5 we did measure.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
