- Strong computer use and coding performance
- Advanced cybersecurity and science reasoning
- Available through the OpenAI API
Pros
- Highest capability OpenAI offers
- Broad strength across coding and agentic work
- Large ecosystem of tools and integrations
Cons
- $10 input and $50 output per million tokens
- GPT-6 Sol is far cheaper for most work

Pricing
GPT-6 Astra is priced by usage rather than by seat: API: $10 in / $50 out per M tokens. That means cost scales with how much text you send and receive, so estimate your monthly volume before committing.
How to get started
Start with one real task you already do each week, give the model the full context, and compare the result with your usual output before changing your workflow. Keep sensitive client or patient data out of consumer chat apps unless your organization has approved the plan.
Alternatives to consider
- ChatGPT (OpenAI, $20/mo): OpenAI's flagship conversational AI.
- Claude (Anthropic, $20/mo): Anthropic's assistant, known for long-context reasoning, careful writing, and safety-aware outputs.
