How do you find o3-pro for coding? I've also been taking the approach of hand building context and copying and pasting it in for complicated tasks where I want lots of reasoning, like bug/security audits.

I found o1-pro unbelievably good for coding, but when o3-pro was released, I saw the response length in ChatGPT was gimped severely compared to o1-pro, so didn't find it all that useful - it couldn't output long enough responses. I actually cancelled my ChatGPT subscription as it seemed like such a downgrade, though I'll probably try using again via OpenAI's API at some point, so long as the response length isn't capped. I'm tempted to try out Grok 4 Heavy.
