Description

OpenAI GPT-6.1 Sol — close to GPT-6 Astra on complex coding, computer use, and professional work, at a lower cost. It supports text and image input, a 1,050,000-token context window, and up to 128,000 output tokens. Reasoning effort ranges from low to max, with medium as the default; none and minimal are not supported, and reasoning tokens are billed as output. When the input exceeds 272,000 tokens, every token in that request is billed at the long-context rate. Use /v1/responses for tool calling; /v1/chat/completions does not support tool calls. On /v1/responses, send the whole conversation in the input array on every turn; requests that carry previous_response_id or conversation are refused.
