# GPT-6.1 Terra

OpenAI released GPT-6.1 Terra, a fast, efficient model combining detailed visual reasoning with precise computer use, priced 50% below GPT-5.6 Terra and GPT-6.1 Sol on the standard API. On Agents' Last Exam at medium reasoning effort it scores 15 percentage points above GPT-5.6 Terra at about one-third the cost, and on Terminal-Bench 4.0 at maximum effort it solves 50.3% of tasks versus GPT-5.6 Terra's published 21.5%. OpenAI notes that GPT-6.1 Sol and GPT-6 Astra remain the better choice for the most complex coding tasks.
