It is absurd to release 5.3-Codex before first releasing 5.3.
Also, there is no reason for OpenAI and Anthropic to be trying to one-up each other's releases on the same day. It is hell for the reader.
Why is it absurd?
I agree, I was confused about where 5.3 non Codex was. 5.2-Codex disappointed me enough that I won't be giving 5.3 Codex a try, but I'm looking forward to trying 5.3 non Codex with Pi.
Because Claude Code is stealing the thunder so OpenAI is focusing on coding now.
