OpenAI ships GPT-6.1 Sol: near-Astra coding and computer use at one-fifth the price

OpenAI released GPT-6.1 Sol, the mid-tier model in the GPT-6 family. It comes close to GPT-6 Astra on agentic coding, computer use and professional work, while standard input and output cost one-fifth of Astra's price. Cached input drops to $0.10 per million tokens.

Why it matters: The post lays out Sol's pricing, context and benchmark comparisons, so you can see where it sits among the three GPT-6 tiers.
