How to Use GPT-6 Astra
Choose between ChatGPT and API access, then use Astra where its premium reasoning and tool capabilities actually matter.
For interactive work, check your ChatGPT model picker. For application or agent workflows, use model ID gpt-6-astra through the OpenAI API when access is enabled for your account.
Use Astra in ChatGPT
OpenAI announced a staged rollout to Plus, Pro, Business and Enterprise users. Rollout availability can vary, so an individual account’s model picker is the most reliable current check.
Use Astra through the API
For programmable access, use gpt-6-astra. The API is the better fit for automation, structured outputs, tool calling, repeatable evaluation, application integration and workloads where you need to measure token cost.
When should you choose Astra?
Astra is positioned for complex reasoning, coding, computer use, research and long multi-step workflows. Its premium API price means it is usually easier to justify when quality, autonomy or context length matters more than lowest-cost generation.
When should you choose a cheaper model?
High-volume classification, straightforward rewriting, simple extraction and other commodity workloads may be more economical on lower-cost models. A sensible production pattern is to route difficult tasks to Astra instead of using it indiscriminately.
