GPT-6.1 Sol: specs, pricing and how it performs in a council

GPT-6.1 Sol is OpenAI's model available on Council AI at $2.00 per million input tokens and $10.00 per million output, with a 1,050,000-token context window. OpenAI's GPT-6.1 Sol (released Sep 29, 2026). Upgrade to GPT-6 Sol, positioned below the GPT-6 Astra flagship: agentic coding, computer use and document-heavy professional work. 1M context. Replaces GPT-5.6 Sol and Terra at the same or lower price. 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-6.1 Sol is good at

OpenAI's GPT-6.1 Sol (released Sep 29, 2026). Upgrade to GPT-6 Sol, positioned below the GPT-6 Astra flagship: agentic coding, computer use and document-heavy professional work. 1M context. Replaces GPT-5.6 Sol and Terra at the same or lower price.

Council surfaces it for: reasoning, coding, agents, complex.

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

GPT-6.1 Sol pricing on Council AI

Council does not resell tokens. Every paid plan carries a monthly budget and each model draws against it at cost: $2.00 in / $10.00 out per million tokens for GPT-6.1 Sol. 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, GLM-5.3 is the cheaper seat in the lineup at $1.40/$4.80.

Using GPT-6.1 Sol in a council

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