Summary
Running GPT-6 Astra at a higher reasoning level costs more per task, but it makes sense when your requirements are clear. It can finish the work faster with less back-and-forth, so if that saves you time and helps you ship sooner, the extra cost can be worth it.
Key points
- Higher reasoning levels cost more per request.
- They pay off most when you know exactly what you want done.
- Less back-and-forth can mean less total time and faster shipping.
- Judge cost by total time-to-ship, not just price per call.
