What a GPT-6 Astra reply cost in our test runs

We sent the same 50 test prompts to every model in llmwise on September 27, 2026, through OpenRouter with llmwise's own prompt and settings. Here's what each GPT-6 Astra reply cost, job by job.

Each GPT-6 Astra cost is the average of what OpenRouter charged us for its replies to one job's prompts; tokens out include any reasoning. Passed: how many of those GPT-6 Astra replies passed their check. In llmwise a GPT-6 Astra message isn't billed by the token.

Across all 50 GPT-6 Astra replies: $0.0117 on average, $0.0092 at the median, $0.0058 for the cheapest and $0.0375 for the dearest. The GPT-6 Astra replies averaged 493 tokens in and 135 out, against the typical message's 4,000 in and 700 out: each test prompt starts a new chat, while a reply deep in a long chat rereads all of it.

Every prompt, and how each reply is scored.

GPT-6 Astra on each llmwise plan

In llmwise a GPT-6 Astra message is one of a published count, however long the reply runs, and you see what's left before you send.

  • Free: GPT-6 Astra isn't in the one-time trial of 5 messages; it takes a paid plan.

  • Pro, $20 a month: up to 31 GPT-6 Astra messages a month, which is $0.65 a GPT-6 Astra message if every message goes to GPT-6 Astra.

  • Max, $50 a month: up to 100 GPT-6 Astra messages a month, which is $0.50 a GPT-6 Astra message if every message goes to GPT-6 Astra.

  • Ultra, $100 a month: up to 225 GPT-6 Astra messages a month, which is $0.44 a GPT-6 Astra message if every message goes to GPT-6 Astra.

  • Studio, $200 a month: up to 500 GPT-6 Astra messages a month, which is $0.40 a GPT-6 Astra message if every message goes to GPT-6 Astra.

  • A $10 top-up adds up to 25 GPT-6 Astra messages, valid 12 months.

Every limit is published. Paid plans also have a monthly fair-use limit on AI cost: Pro $7.50, Max $20, Ultra $42, Studio $85. Using every message on your plan at typical sizes stays under it; very large messages and heavy research use it faster. Every limit, explained.
