I use Claude Max, and I like that Fable can write code and run experiments on its own. I just check in occasionally to see how things are going and suggest the next direction. I expected Claude to be the clear favorite here, but there are more Codex users than I thought, so now I’m tempted to give it a try. That said, GPT translated this comment for me.

I switched to Codex in November 2025 because I couldn't stand the smarmy, "You're absolutely right" anymore. Codex at the time offered less sycophancy and more pushback when I was actually wrong. I also feel it writes cleaner code since it follows my instructions better to not write unrequested code, not create unnecessary abstractions, and not reinvent any wheels. I use LLMs on a tight-leash in HITL for web development, monitoring traces as it goes. I rarely use it for more than just writing code that I specify and I rarely let it "have it's head" and work unmonitored. I use it on the API plan since I need it to be reliable. No outage issues that I can recall.

One significant advantage of Codex subscription over Claude is that you can use any agent harness with it. Meanwhile Anthropic insists that Claude subscription must only be used with Claude Code itself - and I have significant gripes with the quality of Claude Code in general. Also, Fable access was now removed from small 20$ Claude plan, while Codex includes access to comparable model (gpt-5.6-sol) even on small sub…

You can also build your own harness for Claude, right? I think that's not against their ToS?

Not saying it's ideal, just saying it's an option

the ability to let fable work independently, run experiments and only check in occasionally is probably claude's strongest argument here. i'm also surprised by how codex-heavy the replies have been, although the pricing and usage limits seem to explain part of it.

what kind of tasks are you comfortable leaving fable alone with, and how often does it take the project in a direction you need to undo? also, gpt translating the pro-claude comment is a nice ending :)
