Tasks and inputs
GPT-6 Astra is listed for Image-text-to-text, Text generation. It accepts text, image and produces text. Use the publisher’s input format and preprocessing for your chosen deployment.
GPT-6 Astra is OpenAI's model for demanding reasoning, coding and extended agent work. It accepts text and images and produces text.
The specification score summarizes recorded features and limits. It is not a benchmark result.
Pricing conditions: Standard starting rates cover prompts up to 272K input tokens. Longer prompts use 2× input/cache rates and 1.5× output rates for the full request. Fast, Ultrafast, cache writes and tool calls have separate conditions.
Recorded modality support shows what this model can accept and produce. An undocumented modality is shown as unknown rather than assumed to be unsupported.

GPT-6 Astra is OpenAI's model for demanding reasoning, coding and extended agent work. It accepts text and images and produces text.
Astra is a candidate for work where a failed attempt is expensive: debugging a difficult issue, reconciling several documents or coordinating a sequence of tool calls. Its higher token price makes it useful to measure completed-task cost, including retries, rather than compare only the charge for one answer.
Use the Responses API for tool calls. Existing integrations that send tools through Chat Completions need a migration. The model does not accept the none reasoning setting or custom temperature and top_p values; carrying these options over from an older model can break a request.
The documented context allowance is 1,050,000 tokens, with up to 128,000 output tokens. Standard rates for prompts up to 272,000 input tokens are $10 input and $50 output per million tokens. Longer prompts use higher rates across the request; cache writes, processing tiers and regional options can also change the bill.
Keep representative tasks, expected outcomes and failure cases together. Measure total cost to an accepted result, time to completion and the work a person must redo. Compare a smaller route before assigning every request to the same model. Explore OpenAI models or compare two candidates.
Compare the model on the work you need to complete.
GPT-6 Astra is listed for Image-text-to-text, Text generation. It accepts text, image and produces text. Use the publisher’s input format and preprocessing for your chosen deployment.
Documented limits: 1.05M context and 128K maximum output. The listed route has starting rates of $10.00 input and $50.00 output per million tokens. Measure a completed task using the prompts, documents and tools your application will use. Include reasoning and retries in the result.
Use the model identifier and account requirements for the selected API route. Confirm its request limits and output format with one complete task before connecting a larger workflow.
These records share a directory category. Check the source card, output type and deployment requirements before treating a model as a replacement.
