GPT-6 Astra: API Specs, Pricing and Access Boundaries

GPT-6 Astra is identified in official OpenAI documentation as gpt-6-astra, intended for demanding reasoning, coding, research and computer-use work. “GPT 6 Astra” and “GPT-6 Astra” here refer to the same model, not separate products.

Documented API specifications

The model page lists a 1,050,000-token context window, 128,000 maximum output tokens, text input/output and image input. It lists reasoning effort from low through max. Tool capabilities and account limits still need checking in the API route you select; a model name alone does not configure an agent's tools.

Standard API rates

The reviewed model page lists $10 input and $50 output per million tokens, with $1 cached input and $12.50 cache writes. For prompts above 272K input tokens it describes doubled input/cache rates and 1.5× output rates for the full request. Batch/Flex and Fast modes use different rates; use the official pricing table for the selected mode and additional fees.

An API token price is not a ChatGPT subscription price or a guarantee of access in every application. Check your account's available models and limits before planning a deployment.

Evaluate it for a concrete task

Define a result you can inspect, then compare the same input and acceptance criteria with your current model. Count corrections and total cost to finish the task. A demanding model may be useful for difficult work, but its position in a product range does not establish a benefit for every small operation.

Is there a GPT-6.1 Astra?

The OpenAI model catalog reviewed on November 4, 2026 lists GPT-6 Astra (gpt-6-astra) and GPT-6.1 Sol (gpt-6.1-sol) as distinct names. We did not find an official listing for a model named GPT-6.1 Astra in that catalog. This does not establish that an unannounced version was cancelled or why; treat those claims as unverified. Check the actual model identifier available in your account before comparing or purchasing.

Is GPT-6.2 Astra an officially listed model?

The OpenAI model catalog, checked November 5, 2026, lists GPT-6 Astra and GPT-6.1 Sol separately. It did not list a model named GPT-6.2 Astra at that time. Search results and rumours do not establish an announced release date, performance or price; verify the exact model ID in official documentation and your account.

Is GPT-6.2 listed?

The complete OpenAI API model catalog, checked November 7, 2026, did not list a GPT-6.2 text model. It did list GPT-6 Astra and GPT-6.1 Sol, and separately listed GPT Image 2.6 image models. Similar numbers do not make those the same product; check the exact model identifier and current official listing before assuming availability or pricing.
