#12Earlier quoted context omitted.
hadn't come across either of these before, thanks. using both behind the same harness sounds really interesting. do you still choose claude vs codex depending on the task, or has the harness made them mostly interchangeable? what took the longest to learn?
It's vibes mostly. Like, fable is better on frontend while 5.6sol is better at long running tasks with a lot of subtasks, harness did made them mostly interchangeable as well as able to have them both participate in solving a hard issue. Longest to learn is the ui (I'm more of a GUI guy but this is just too good) and all hundreds of features where you want to do something and then discover the harness already support…

#14One 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 subscription.

#16I mostly use claude, its actually good at context specially opus 4.8

#18I use both. Claude I use up to 5, and Codex I use up to 20 for PRO.
Personally, I think Codex is better. Aside from the frequent resets, since the Fable incident, there have been cases where connections drop. For writing code, Codex generally does a better job. That said, I feel Fable is better for overall structure, but ultimately, it varies from person to person. I use both as my coding assistants

Re: Ask HN: Claude Code or Codex?
#20I’ve been using both, but I find 5.6 sol is faster in terms of wallclock time and far less chatty (on my small projects in non-legacy code bases).
It “feels” like Sol gets off track more easily than Fable (it’s hard for Sol to ignore a stray remark). My theory is this comes from smaller context window - Codex uses a 350K token context window (that you can’t change), even though model can handle more…
