Claude Opus 4.8 is Anthropic's Opus-tier workhorse for judgment, honesty, and getting careful assistant work done without Fable's price. Our tests show excellent instruction following and comprehension, high helpfulness, and strong empathy when users need measured advice. Creative writing is a clear weak spot versus older Opus releases: our tests find it flatter and less nuanced than even Opus 4.6, more "finished the draft" than literary. Strong for serious conversation and knowledge work; look elsewhere—or to Fable—when voice and prose are the point.
