On the @ArtificialAnlys Intelligence Index, GPT-6 Astra at Max reasoning scores higher and costs less per task than Opus 5 at High. If the benchmark reflects your workloads, you can switch to Astra, turn reasoning all the way up, and still spend less. For us at @OpenAI, making intelligence accessible includes making it affordable. What matters is the total cost of getting work done to the quality you need, including retries and human review. Bringing that cost down gives everyone more room to experiment and makes more ambitious projects worth pursuing, whether you’re building on your own or putting AI to work across a company.
