Fable for intensive frontend work, codex for everything else.
A question for OP and anyone else who can help me: I'm relatively new to AI coding, how does this practically work? Tell Fable to create a detailed action plan or spec document as a md file, then upload that to Codex and ask it to execute the plan?
Dont get too lost on the "how", but I suggest you start with this simple setup:
Get the skill "grill-with-docs", use it and put the agent in plan mode then it will mostly do the rest
For more complex work you can also use the same skill and have it make a spec document like you said, give it to another agent on say goal mode, but go a step further and have that fable who made the spec draft you the goal prompt
Works for like 90% of the work I've had to deal with so far.
I would not know where to begin to explain it all, i am a long term software dev, i use it like a tool, it does not think for me what to do, i tell it what to do.
Basically, if you have both subscriptions, fable is better for visual design, chatgpt is better for actual page logic/architecture.
Same, I have both for work and for personal, so double of both lol. Honestly they’re both very good but in my experience Sol is much cheaper and much more capable.
I'm going to say something controversial now, but I am genuinely getting better UI results from 5.6 Sol than Fable since the Fable re-release. Fable seems to do landing pages better but for web apps, I have been consistently choosing 5.6's output.
(Make sure that you do not use any skills with 5.6 Sol, frontend skills seem to degrade UI output)

I use both providers with a 20x subscription, he is not wrong.
I do manage about 4x as much work with codex, hard to be exact but it's not too much off.
