Benchmarks
Independent benchmark results
Scores come from independent evaluators that ran the model themselves, pinned to a dated snapshot. Rank is among current models in the same snapshot. OpenAI's own launch figures are listed under strengths with the publisher named, because they are not measured the same way.
No independent benchmark has published a result for GPT-6.1 Terra yet. It is still compared below on price, context and capabilities.
Fit
Strengths, cautions and best uses
- Strengths
- Half GPT-6.1 Sol's rates at $1 input and $5 output per 1M tokens, with cached input at $0.05; Batch and Flex halve them again
- The same 1.05M-token context and 128K maximum output as GPT-6.1 Sol, with image input and six reasoning effort levels from none to max
- Runs the Responses API tools, including computer use, web search, file search, code interpreter and MCP
- Cautions
- Prompts over 272,000 input tokens bill the whole request at $2 input and $7.50 output per 1M tokens
- Reads text and images only: audio and video input are not supported
- Released on 26 October 2026, so no independent benchmark score is recorded here yet
- Best for
- Computer-use and tool-calling agents at half GPT-6.1 Sol's price
- High-volume reasoning work that stays under the 272K long-context threshold
