… 3 This translates into Claude Opus 4.6 obtaining a higher score than GPT-5.2 on this eval approximately 70% of the time where 50% of the time would have implied parity in the scores . For GPT-5.2 and Gemini 3 Pro models, we compared the best reported model version in the charts and table. …
… It’s a great model to build with. On our Super-Agent benchmark, Claude Opus 4.8 is the only model to complete every case end-to-end, beating prior Opus models and GPT-5.5 at parity on cost. …
… Because higher-resolution images consume more tokens, users who don’t require the extra detail can downsample images before sending them to the model. For GPT-5.4 and Gemini 3.1 Pro, we compared against the best reported model version available via API in the charts and table. …
… Footnotes For GPT-5.2 and Gemini 3 Pro, we compared against the best reported model version available via API in the charts and table. …
… Evaluations of the final production model show a very similar pattern of results when compared to other Claude models, and are described in detail in the Claude Opus 4.5 system card . …
… Claude Fable 5 is the strongest model we've tested on frontier physics research while using a third of the reasoning tokens. In 36 hours it got nearly to where GPT-5.5 landed after four days. …
