GPT-6.1 Sol brings near-Astra capability down to one-fifth the price
GPT-6.1 Sol gives developers an OpenAI model aimed at agentic coding, computer use, and professional workflows for $2 per million input tokens and $10 output, versus GPT-6 Astra’s $10 and $50. It handles work such as debugging real codebases and answering questions from complex PDFs, while cached input costs $0.10 per million tokens. OpenAI says it matches Astra on DeepSWE v1.1 at roughly one-fifth the cost.
