GPT-6 Astra
OpenAI's flagship and most capable model, built to carry hard reasoning, coding, computer use and research from a request to a finished result. The most expensive model on OpenAI's general price card.
Model ID: gpt-6-astra
What that means
A worked example
Per-token pricing is hard to feel. Take a moderately chatty production workload: 100 calls a day, roughly 10,000 tokens in and 2,000 out each time. On GPT-6 Astra that comes to about:
$600 / month
Before caching, batching or volume discounts, all of which move this number a long way. Illustrative only.
