Measured Coverage and Estimates
GPT 5.1 has 23 of 39 tracked IQ benchmark inputs across 7 of 7 dimensions. Raw benchmark tables contain source-backed results only. Derived IQ combines all six dimensions using the shared scoring methodology, including estimates where direct coverage is incomplete. Configured predecessor references: GPT 5, O3. A reference is an estimation input, not evidence that this model has the predecessor's measured results.
Among dimensions with direct benchmark coverage, this profile's highest estimated scores are Academic Reasoning (IQ 123) and Programmatic Reasoning (IQ 119). These dimension estimates can include statistical adjustments or predecessor priors; they are not raw benchmark percentages or claims of real-world task success.
Benchmark versions, evaluation harnesses, and coverage affect comparisons; a missing result is not a score of zero. See the scoring methodology for estimation and uncertainty limits.

Frequently Asked Questions
- What is the IQ of gpt-5.1?
- gpt-5.1 has an estimated IQ of 112, which ranks #61 out of 164 public models on the AI IQ leaderboard. The score combines seven equally weighted reasoning dimensions using measured benchmark results and conservative estimates for missing coverage.
- What is the EQ of gpt-5.1?
- gpt-5.1 has an estimated EQ of 116. EQ measures emotional reasoning — how well a model reads and responds to emotional context — and is scored separately from IQ.
- How much does gpt-5.1 cost?
- gpt-5.1 costs $1.25 per million input tokens and $10.00 per million output tokens. Adjusted for how many tokens it actually consumes on real tasks, its effective cost works out to $14.20 per million input-plus-output tokens.
- Is gpt-5.1 open source?
- No — gpt-5.1 is a proprietary model. Its weights are not publicly available, so it is used through hosted APIs and products.
- When was gpt-5.1 released?
- gpt-5.1 was publicly released on November 13, 2025.
- How fast is gpt-5.1?
- In independent measurements, gpt-5.1 generates about 115 tokens per second, with a typical response time of about 35 seconds.
