I believe it is a widely accepted opinion that agentic coding took off with Opus 4.5 late in 2025.

Why would you attempt to use GPT 5.3 to generate code today and form an opinion on that basis?

I do not think it is even still available in Codex, I believe it only has the smaller, distilled GPT 5.3 Codex Spark.
