OpenAI’s GPT-6.1 Sol can accept a 1,050,000-token context window , but its lower pricing tier ends much earlier. Once input exceeds 272,000 tokens , OpenAI applies higher input, cache, and output rates to the entire request —not just the tokens above the boundary. That discontinuity changes the production decision. GPT-6.1 Sol is not economical simply because its headline rates are $2 per million input tokens and $10 per million output tokens. Its value depends on four workload-specific variables: context length, realized cache reuse, reasoning effort, and the cost of producing an accepted result .
