GPT-6.1 Sol is out at $2/$10 per 1M tokens, pitched as near-Astra for less

OpenAI launched GPT-6.1 Sol at DevDay. OpenRouter lists it at $2 in and $10 out per 1M tokens, the same as GPT-6 Sol, with about 1M tokens of context. AWS says it is now on Bedrock.

Why it matters: OpenAI says it matches GPT-6 Astra ($10/$50) on DeepSWE v1.1 at about a fifth of the cost per task, per AWS. If you pay Astra prices, test Sol on your own work.
