Anthropic 发布 Claude Opus 5：接近前沿智能，成本仅为 Fable 5 一半

Insane: Anthropic just launched Claude Opus 5: near-frontier intelligence at roughly half the cost per task. According to Anthropic’s benchmarks, Opus 5: -Comes within 0.5% of Fable 5 on CursorBench at half the cost -Beats Fable 5 on OSWorld at just over one-third of the cost -Scores 3× higher than the next-best model on ARC-AGI 3 More than doubles Opus 4.8’s Frontier-Bench performance The model also checks its own work more carefully. In one test, it built a computer-vision pipeline to understand an image it could not view directly, then recreated the object as a 3D model. Opus 5 costs the same as Opus 4.8: $5 per million input tokens and $25 per million output tokens. It is now the default model for Claude Max and the strongest option on Pro. Absolute insane launch! Everything I was hoping for. Literally Fable 5 at Opus pricing. Now its just a matter of days before we get an update to Fable id say    > **引用原帖 Chubby♨️ (@kimmonismus):** > HERE WE GO: OPUS 5 > And it outperforms Fable 5 almost on all evals!!
