Dear Team
For coding tasks, which model should I choose?
I’m trying both, and I Think my sentiment lies with Codex 5.3
But Im not always sure. 5.4 is also really good.
@openai Team - what do you suggest specifically for coding?
Languages Im using Python, Typescript
Application type: Against Realtime API openAI, Voice Agents
Thanks so much God bless
