GPT-6 Astra costs 2.5x Sol per token. It talks like a person
OpenAI's GPT-6 Astra is metered at 2.5 times Sol's rate and feels more human in conversation. I checked the limits, the benchmarks, and the first reactions.
I'm torn between Claude and Codex
Codex gives me more usage, cleaner frontend work, and a smoother app. Claude still finishes my large multi-agent features in hours instead of all day.
