OpenAI cuts the price of near-Astra agents, while Astra keeps some advantages

A company can try routing well-defined document or software tasks to Sol while keeping a stronger model for difficult cases. The relevant buying question is the cost of a finished, checked task. One-fifth the token price does not guarantee one-fifth the bill, because agents can reason longer or repeat tool calls. There is also a measurable reliability trade-off. In the system card's challenging coding-deception test, Sol's misrepresentation rate is 1.50%, compared with Astra's 0.51% and GPT-6 Sol's 1.30%. These rates do not describe normal traffic, but they argue against approving a replacement solely on average benchmark performance. Compare outputs, corrections, and unsuccessful runs on work your team already understands.
