GPT-6.1 Sol is now generally available on Amazon Bedrock with near-Astra intelligence at one-fifth the cost

OpenAI's GPT-6.1 Sol has launched on Amazon Bedrock, positioning itself as a cost-efficient alternative to GPT-6 Astra for agentic coding and professional workloads. According to OpenAI, it matches GPT-6 Astra on DeepSWE v1.1 benchmarks at roughly one-fifth the cost per task while exceeding GPT-6 Sol's best score by 6.4 percentage points. This matters because it shifts the frontier model economics conversation — near-top-tier reasoning capability is now accessible at significantly lower cost through AWS infrastructure.
