OpenAI Releases GPT-6.1 Terra with Enhanced Vision and Computer Use at Half the API Cost
OpenAI has introduced GPT-6.1 Terra, a mid-tier model boosting vision and computer operation capabilities at half the API price of GPT-6.1 Sol, now available for developers and paid subscribers.
OpenAI has launched GPT-6.1 Terra to strengthen vision comprehension and computer use capabilities for AI agents at lower operational costs. Official tests show Terra approaches high-tier models in specific tasks. Standard API pricing is set at $1 per million input tokens and $5 per million output tokens, half the price of Sol.
Key takeaways
- In the Agents’ Last Exam benchmark—which includes tasks such as building 3D models from architectural drawings—Terra scored 15 percentage points higher than GPT-5.6 Terra at medium reasoning effort, at one-third the cost.
- Terra solved 50.3% of tasks at maximum reasoning in Terminal-Bench 4.0, while OpenAI's internal hallucination-triggering test showed its low-reasoning error rate dropped from 53.6% to 16.7%.
