GPT-6 Astra pricing on Council AI

Council does not resell tokens. Every paid plan carries a monthly budget and each model draws against it at cost: $10.00 in / $50.00 out per million tokens for GPT-6 Astra. Plans start at $19.99/mo (Plus), $39.99/mo (Pro) and $99.99/mo (Ultra, which adds media review, the personal RAG library and MCP server).

If budget is the binding constraint, Claude Opus 5 is the cheaper seat in the lineup at $5.00/$25.00.

Using GPT-6 Astra in a council

A single model — this one included — can be confidently wrong. Council runs GPT-6 Astra alongside models from other labs on the same prompt, then scores how much they agreed. High consensus is a signal you can act on the answer; low consensus surfaces the specific point they split on, which is usually the part worth checking yourself.

Other OpenAI models in the lineup: GPT-5.6 Sol, GPT-5.6 Terra, GPT-5.6 Luna.
