Harvey made Claude Opus 4.7,
Anthropic's latest frontier model, available in its platform.
The model scored 90.9% on Harvey's BigLaw Bench evaluation suite, the highest score of any Claude model in Harvey to date, with 45% of tasks receiving perfect scores.
Harvey noted improved reasoning calibration and performance on ambiguous tasks, but also some polish gaps relative to Opus 4.6, such as tone mismatch and non-standard citations.
