GPT-6.1 Terra
proprietaryReleased Oct 26, 2026
OpenAI's efficient GPT-6.1 model for image-based reasoning, screen interaction, writing and focused coding tasks. Accepts text and images and generates text, with a 1,050,000-token context and up to 128,000 output tokens. Reasoning effort ranges from none to max, with medium as the default. Streaming and structured outputs are supported; tool calling requires the Responses API, not Chat Completions. Fine-tuning, audio and video are not supported. Standard prompts above 272K input tokens cost 2x the input/cache rates and 1.5x the output rate for the entire request; Fast mode and regional processing have separate premiums.
