How to choose
Which OpenAI model you should use depends on how much of GPT-6: Astra's frontier reasoning, 1,050,000-token context, and Critical-tier cybersecurity capability your workload actually needs. For most production workloads a cheaper GPT-5.x model is the right default; reserve Astra for genuinely frontier-scale tasks.
