GPT-6.1 Terra: computer use at lower token cost
API pricing: $1 input / $5 output per million tokens at launch; also in Work and Codex.
- Focus: Visual reasoning, computer use, and writing. Announced tasks include interpreting drawings, completing forms, and entering invoice data into accounting software.
- API model: gpt-6.1-terra. Standard prices per million tokens: $1 input, $0.05 cached input, $5 output.
- App access at launch: ChatGPT Work and Codex for Plus, Pro, Enterprise, and Edu users.
- Tradeoff: OpenAI positions Terra for lower-cost everyday work; it still recommends Sol or Astra for the most complex coding tasks.
- Requirement: Computer-use workflows need an agent environment and application access. The model alone does not connect to your accounting system. Published benchmark gains do not establish accuracy on your documents.
