GPT-6.1 Sol cuts Astra token prices by 80%

OpenAI launched GPT-6.1 Sol at one-fifth of GPT-6 Astra’s standard input and output prices, with API rates of $2 per million input tokens and $10 per million output tokens. A launch report says Sol nearly matches Astra on agentic coding, computer use, and professional work; the API model page lists cached input at $0.10 per million tokens, 95% below standard input. Builders should benchmark their tool-call and cache mix before defaulting to the costlier frontier model; the Astra gated rollout is the relevant reminder that lower price does not erase deployment constraints.
