we’ve heard you on speed. GPT-6.1 Terra is fast 🌎 on Agents’ Last Exam, Terra completes tasks over 3× faster on average than GPT-6 Astra and GPT-6.1 Sol. this benchmark tests how well models use a computer to do professional work, like turning architectural drawings into 3D models or reviewing a film shot by shot. at medium effort, Terra also matches Astra’s performance on the benchmark at 1/10th the price per token. at max effort, it costs roughly 9× less per task than Claude Opus 5.5. Terra is a great everyday model for writing, understanding visuals, and getting things done across apps. early testers have been using it for video editing and 3D creation, too. Sol and Astra are still generally more reliable for complex coding. but for everyday work, give 6.1-Terra a try and let us know what you think!
