About GPT-6 Astra
GPT-6 Astra is OpenAI's most capable GPT-6 model, made for the hardest reasoning, coding, computer use, research, and document creation. OpenAI calls it its most intelligent and aligned model and reports leading results on computer use, browsing, and software engineering. It takes text and images, calls tools, and offers reasoning effort up to max. Sol and Luna are its cheaper descendants.
Where it works well
- OpenAI reports leading results in computer use, browsing, software engineering, cybersecurity, and science.
- Reasoning effort runs from low to max, giving the widest thinking range of any GPT-6 model.
- Can operate software for you: filling online forms, updating CRM records, and running front-end checks.
- OpenAI describes it as its most aligned model, with better handling of user intent and boundaries.
When to choose another model
- Sol, 6.1 Sol, and Luna deliver much of Astra's behavior at lower cost, so Astra is rarely the right default for routine traffic.
- Reasoning at high effort lengthens responses, so latency-sensitive chat is better served by a smaller GPT-6 model.
Getting started
Create API key
Create a key in Console, then use it with every model on the platform.
Send your first request
Copy the example for your language and run it against the endpoint.

Pricing
The Verified price applies to Verified, which costs less on most models. The Official price is the model maker's published price and applies to the more reliable Official route. Auto bills the route that completes the request.

Usage & activity
Success rate is the share of requests that completed. Latency is how long a full response takes; P95 means 95% of requests finished within that time.

Use cases
Best for- Code
- Reasoning
- Vision
Computer-use agents
Let it browse, fill forms, and update records in business software where no API exists, with a person reviewing the result.
Research and mathematics
Hand it open-ended problems that need long chains of reasoning and verification of intermediate results.
Large codebase engineering
Plan and carry out refactors or feature work across a big repository, running tests as it goes.
Professional documents
Draft contracts, analyses, and decks from source material with structure a reviewer can check.
Prompt examples
Open the vendor portal, download last month's invoices, match them against this spreadsheet, and list the mismatches.
Prove or find a counterexample for the following conjecture, and show each step you rely on.
Migrate the notifications service from callbacks to async functions, update the tests, and summarize the risky spots.
This model has conditional pricing. Monthly token totals alone cannot produce a reliable estimate; use the detailed pricing for the request specification, cache, and applicable time window.
FAQ
What is GPT-6 Astra?
GPT-6 Astra is the top model of OpenAI's GPT-6 generation, aimed at demanding reasoning, coding, computer use, research, and professional document work. Sol and Luna are the faster, cheaper models built from its advances.
What reasoning effort levels does Astra support?
OpenAI lists low, medium, high, xhigh, and max for Astra. The none setting is not available, so every request involves some reasoning. Lower the effort to cut latency on simple calls.
When should I choose Astra over GPT-6.1 Sol?
Choose Astra when accuracy on the hardest tasks justifies the extra cost. GPT-6.1 Sol matches Astra on some coding evaluations at far lower cost, so test it first.
Can GPT-6 Astra control a computer?
OpenAI reports it as the leading model for computer use, such as filling forms and organizing calendars. Build in human review for actions with real consequences, since agents can still misread a screen.
Does Astra accept images?
Yes. It accepts images alongside text, supports tool calling and JSON schemas, and replies in text, so a screenshot or diagram can go straight into a prompt.
How much does GPT-6 Astra cost?
On TokenLab, GPT-6 Astra costs Input $3.00 / Output $15.00 per 1M tokens. The pricing table above shows the full breakdown. Rates depend on the billing unit, specification, and usage. Compare matching conditions in the model's detailed pricing; a single rate does not determine the total cost.
What are the context window and output limit of GPT-6 Astra?
GPT-6 Astra accepts up to 1,050,000 tokens of context and returns up to 128,000 tokens in one response.
Which endpoint should GPT-6 Astra use?
