GPT-6 Sol is the cost-efficient high-end model in OpenAI's GPT-6 series, positioned below the flagship GPT-6 Astra and above the fast GPT-6 Luna tier. It is suited for demanding professional and agentic work. Multimodal input (text, image, file), 1.05M-token context, configurable reasoning effort, tools and structured outputs.

Multimodal input (text, images and files) with text output, a ~1.05M-token context window and up to 128K output tokens. Supports configurable reasoning effort, function calling / tools, structured (JSON) outputs and seeded sampling. The model is moderated by the provider.
Pricing is tiered by prompt size: the standard rate applies up to 272K input tokens and steps up beyond it. Cached input reads are billed at a reduced rate. See the pricing on this page for the current numbers.
POST /v1/chat/completions with model openai/gpt-6-sol through your OrcaRouter API key — any OpenAI SDK works by setting the base URL to OrcaRouter. Supports tools / function calling, response_format for structured outputs, and reasoning_effort to tune depth. Errors use the OpenAI error envelope.
