| Modalities | text, image |
| Context window | 1,050,000 tokens |
Rolling out to ChatGPT Plus, Pro, Business, and Enterprise, and to developers through the OpenAI API, Microsoft Azure, and AWS Bedrock
Publisher-reported capabilities
- OpenAI positions GPT-6 Astra as its most capable model for complex reasoning, coding, computer use, research, and document creation.
- The API supports low, medium, high, xhigh, and max reasoning effort with a 1.05M-token context window.
Limitations and availability caveats
- Access is rolling out in phases rather than being immediately available to every eligible user.
- OpenAI reports reduced chain-of-thought monitorability relative to GPT-5.6 Sol and applies additional monitoring and access controls because Astra reaches its Critical cybersecurity capability threshold.

Measured Coverage and Estimates
GPT 6 Astra has 31 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 5.6 Sol, GPT 5.5. 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 Programmatic Reasoning (IQ 151) and Mathematical Reasoning (IQ 150). 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.
