▲ OpenAI just released GPT-6.1 Terra, a fast model that does Astra-level computer use at a fraction of the cost.
The key idea is cost per task, not peak score. Terra looks at screens, drawings and photos, reasons at a dial-able effort level, then clicks and types through the computer-use tool. OpenAI tuned it for high-volume work like forms, invoices and technical drawings.
On Agents' Last Exam v1 at medium effort, Terra scores 57.6% at $0.29 per task. GPT-6 Astra scores the same 57.6% at $4.82 per task. It also hits 85.5% on MMMU-Pro, close to Astra's 86.7%. It is a trade-off though: on Terminal-Bench 4.0 it solves 50.3%, behind GPT-6.1 Sol (55.9%) and Claude Sonnet 5.5 (70.6%).
Available now in the API as gpt-6.1-terra, plus ChatGPT Work and Codex. 1.05M context, closed weights, 5 per million tokens, half of Sol......
