alt Hacker News> Use Claude 4.5 Opus
In my org we are experimenting with agentic flows, and we've noticed that model choice matters especially for autonomy.
GPT-5.2 performed much better for long-running tasks. It stayed focused, followed instructions, and completed work more reliably.
Opus 4.5 tended to stop earlier and take shortcuts to hand control back sooner.

Interesting! Was kinda disappointed with Codex last time I tried it ~2m ago, but things change fast.
a ralph loop can make claude go til the end, or to a rate limit at least.
opus closes the task and ralph opens it right back up again.
i imagine there's something to the harness for that, too
