Briefings
OpenAI released GPT-6.1 Terra, a model emphasizing visual reasoning and computer use, priced at $1/million input tokens and $5/million output tokens. It is positioned similarly to Anthropic's Sonnet, offering a midrange option for technical communication and automated tasks, with Ted Sanders noting it is faster than Astra and Sol while cheaper than Sol. The release includes a new pricing grid comparing all GPT-6 reasoning levels.
Key points
- GPT-6.1 Terra is priced at $1/million input tokens and $5/million output tokens, making it significantly cheaper than GPT-5.6 Terra and GPT-6.1 Sol.
- Ted Sanders on Hacker News suggests GPT-6.1 Terra is better than Astra and Sol for technical communication and computer use, though it is slower than Astra and Sol.
Context
GPT-6.1 Terra is part of OpenAI's generative AI lineup, competing with Anthropic's Sonnet. It is positioned as a midrange option for API developers and subscribers, specifically for tasks requiring visual reasoning and computer use, such as drafting proposals and interpreting technical drawings.
Limitations
Evidence is limited to a single article from October 2026. Pricing data is snapshot-based and does not account for future pricing changes or regional variations. Ted Sanders' assessment is a user comment, not a formal model evaluation. Specific performance metrics for other tasks are not provided.
