GPT-6.1 Terra has half the API input and output rates of GPT-6.1 Sol
GPT-6.1 Terra costs 1 USD per million input tokens and 5 USD per million output tokens through the API, half the rates for GPT-6.1 Sol. According to OpenAI, it focuses on office tasks, visual reasoning and automated software operation.
GPT-6.1 Terra has API rates of 1 USD per million input tokens and 5 USD per million output tokens. GPT-6.1 Sol costs 2 USD and 10 USD in the same units, so both rates are 50 % lower for the new model. Cached input tokens for GPT-6.1 Terra cost 0.05 USD per million.
OpenAI released the model on 26 October through Responses API and Chat Completions API. It is also available in ChatGPT Work and Codex for users on Plus, Pro, Enterprise and Edu plans. According to OpenAI, its intended uses include drafting documents, interpreting technical drawings, filling in forms and editing video.
According to Ted Sanders of OpenAI, GPT-6.1 Terra is probably better at technical communication than GPT-6 Astra and GPT-6.1 Sol and offers similar capabilities in visual tasks and computer use at significantly higher speed. According to Artificial Analysis, it outperformed GPT-5.6 Terra by six points in the Intelligence Index at the maximum reasoning level; costs in this evaluation were 0.40 USD versus 1.40 USD per task.
Sources differ in their descriptions of the price difference compared with GPT-5.6 Terra: some describe the price as half as much, while also citing the previous rates of 2 USD per million input tokens and 12 USD per million output tokens. These figures imply a reduction of 50 % for input and approximately 58 % for output.
Why it matters
Lower rates matter particularly for large volumes of recurring automated tasks; cached inputs have a separate, significantly lower price. However, the cost per completed task needs to be assessed alongside token usage and success rates. For occasional use through a subscription, the claimed differences in speed and communication quality matter more; lower API prices alone do not mean a cheaper subscription.
