GPT-6 Luna: specs, pricing and how it performs in a council

GPT-6 Luna is OpenAI's model available on Council AI at $0.10 per million input tokens and $0.50 per million output, with a 1,050,000-token context window. Fast, cost-efficient tier of OpenAI's GPT-6 series (released Sep 22, 2026). 1M context at $0.10/$0.50, half the price of GPT-5.6 Luna. On Council you do not run it alone: the same prompt goes to up to 10 models from different labs in parallel, and a moderator synthesizes one answer with a consensus score showing where the labs agreed.

What GPT-6 Luna is good at

Fast, cost-efficient tier of OpenAI's GPT-6 series (released Sep 22, 2026). 1M context at $0.10/$0.50, half the price of GPT-5.6 Luna.

Council surfaces it for: general, fast, high-volume.

It has native web search, so it can ground answers in current sources rather than training data alone.

GPT-6 Luna pricing on Council AI

Council does not resell tokens. Every paid plan carries a monthly budget and each model draws against it at cost: $0.10 in / $0.50 out per million tokens for GPT-6 Luna. 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).

Using GPT-6 Luna in a council

A single model — this one included — can be confidently wrong. Council runs GPT-6 Luna 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-6 Astra, GPT-6.1 Sol.
