OpenAI releases GPT-6.1 Terra model at half the API price

OpenAI released its updated mid-tier artificial intelligence model, GPT-6.1 Terra, on Monday, October 26, 2026. Decrypt and OrcaRouter reported that the new model costs developers 50 percent less than the previous GPT-5.6 Terra version via application programming interface access rates. [1][2][5]

According to Decrypt, the updated model focuses on routine office tasks including reading screens, navigating through software applications, and drafting replies. OpenAI refers to these screen reading and navigation capabilities as computer use. Decrypt added that the updated model executes these automated computer tasks faster and with greater accuracy than its predecessor. [1]

OrcaRouter reported that the model operates with 37 fewer error points compared to earlier benchmarks. Android Headlines reported that the model provides control capabilities similar to flagship artificial intelligence tools at a lower operational cost. [5][6]

The GPT-6.1 model family, which includes the Sol and Terra variants, was originally introduced by OpenAI on September 29, 2026. As FTMQ Crypto reported earlier, OpenAI published 722 artificial intelligence generated mathematics manuscripts on GitHub earlier in October 2026, which faced calls for public verification from academic researchers.
