{"slug": "gpt-6-1-sol", "title": "GPT-6.1-Sol", "summary": "OpenAI released GPT-6.1 Sol, a model the company says delivers near-Astra performance at a lower cost for complex coding, computer use, and professional work, priced at $2.00 per 1M input tokens and $10.00 per 1M output tokens. The model supports reasoning.effort levels of low, medium (default), high, xhigh, and max, but not none or minimal, and requires the Responses API for tool calling, with Chat Completions supported without tool calling. GPT-6.1 Sol offers US and EU data residency, though Fast mode is unavailable with EU data residency, and prompts exceeding 272K input tokens are billed at 2x input and cache rates and 1.5x output for the full request.", "body_md": "Near-Astra performance for complex work at a lower cost.\n\nNear-Astra performance for complex work at a lower cost.\n\nCompareTry in Playground\n\nReasoning\n\nHighest\n\nSpeed\n\nFast\n\nPrice\n\n$2•$10\n\nInput•Output\n\nInput\n\nText, Image\n\nOutput\n\nText\n\nGPT-6.1 Sol delivers near-Astra performance at a lower cost for complex coding,\ncomputer use, and professional work.

See data residency eligibility.\n\nPricing is based on the number of tokens used, or other metrics based on the model type. For tool-specific models, like search and computer use, there’s a fee per tool call.
