GPT-6.1 Sol is live on OpenRouter at $2 per million input tokens

OpenRouter is now offering OpenAI’s GPT-6.1 Sol. Input is priced at $2 per million tokens and output at $10 per million tokens. Cached input costs $0.10 per million tokens, which OpenRouter says is half of GPT-6 Sol’s cached price.

OpenRouter says GPT-6.1 Sol nearly matches GPT-6 Astra on agentic coding, computer use, and professional work at one-fifth of Astra’s price.
