OpenAI Ships GPT-6.1 Terra With Computer Use at Scale at $1 Input/$5 Output per Million Tokens

OpenAI released GPT-6.1 Terra as a mid-tier model touting 'fast and capable computer use at scale' and more natural writing, priced at $1 per million input tokens and $5 per million output tokens — roughly half the cost of GPT-6.1 Sol. Early coverage reports a ~3x speed-up over GPT-5.6 Terra and the low-reasoning error rate dropping from 53.6% to 16.7%, with programming scores at max reasoning rising from 21.5% to 50.3%. The model is positioned as the default swap-in for Sol in CI review, integration and code review loops.
