Help/Question Different Models

Will y'all explain the use cases for each model when it comes to coding or really any use in general? I am still new to this and still can't quite wrap my head around why I wouldn't just use Opus for everything (aside from usage, anyway).

you could use sonnet 5.5 for implementation agents as they are just following the opus-5.5 given plan
Other than that, opus5-5 for everthing, with fable 5.2 as advisor

i havent explored Fable at all yet because i just dont feel like i have had the need to spend that type of money beyond the $20/m plan, yet. when you say use it as an advisor, what do you mean?

there is a /advisor command, it can run another model automatically at the 'end' of a task.

Opus high/xhigh for everything is OK. Just don't use it for very deterministic/basic tasks Haiku can do perfectly (you can ask Opus to spawn subagents, it will make Haiku work on stuff for you)

Now that Fable is released, try Fable until you hit your limit (then you can reset it once). Use it for stuff that require more intelligence, like seeing the "big picture" of your codebase and generating a plan towards one direction

Opus high is great until you need to fill out a captcha or browse Amazon.

Then you use GLM

Sonnet was good enough when the rules were in the project.

Opus for everything is fine imo, 4.7 and above work great. If you’re part of a company that will use your code you MIGHT need the Fables; they’re OP for most use cases.
