It reads text and image input, calls tools, returns structured output, and works within a 1.05M-token context window, so a long task can keep its code, documents and tool results together in one request. It has a 1.05M-token context window and can generate up to 128,000 output tokens. It accepts text and image input and returns text. Its knowledge cutoff is April 20, 2026, and it was released on September 22, 2026. ## Capabilities GPT-6 Sol supports reasoning, tool calling, structured output and image understanding. It accepts text and image input and returns text. OpenAI notes that its image understanding applies to visual tasks, including computer use. Together with tool calling, this lets it work through multi-step jobs that mix reading, deciding and acting. ## Pricing GPT-6 Sol is priced from $2.00 per 1M input tokens and from $10.00 per 1M output tokens. Cached input reads are priced from $0.20 per 1M tokens. GPT-6 Sol is available through RealRelay's OpenAI-compatible API. ## Use cases Use GPT-6 Sol for coding agents that read a repository, plan a change, call tools to edit and test code, and report back. The 1.05M-token context window keeps the code and the history of tool calls in one request. It also suits agentic workflows that combine documents and screenshots, where image input is read alongside text and structured output feeds the next step. ## Call it OpenAI-compatible chat completions: ```bash curl https://www.realrelay.ai/v1/chat/completions \ -H "Authorization: Bearer $REALRELAY_API_KEY" \ -H "Content-Type: application/json" \ -d '{"model": "openai/gpt-6-sol", "messages": [{"role": "user", "content": "Hello"}]}' ``` ## FAQ ### What is GPT-6 Sol?
