Cost/1M tokens
OpenAI's GPT-6.1 Terra is a fast, efficient model presented as a step up from GPT-5.6 Terra, positioned at what the maker calls the cost-intelligence frontier with a new balance of speed, capability, and cost. OpenAI claims it nearly matches its most capable frontier models on visual reasoning and computer use while costing much less. It is built for computer-use agents and everyday work tasks such as drafting proposals, interpreting technical drawings, filling out forms, and editing videos.
