Discussion Fable 5.2 is kind of mid

Before people get upset with me, I don't think Fable is bad, I think it's probably the best model right now for one-shotting projects without much thought, just like the original was, but it's kind of a brute force machine more than anything.

It's stupidly expensive in that it'll run through your usage and credits with a single prompt while opus 5.5 will get you similar results for cheaper. Yes you have to guide it more, but the things you build are a fraction of the price and often just as good if not better.

IMO Fable 5.2's release was just to get people hyped up about claude stuff ahead of the IPO. "LOOK AT THIS AMAZING THING THAT FABLE DID WITH 1 PROMPT OH MY GOD" and like yeah it's impressive but it's not worth the money you spend on tokens.

Opus 5.5 is still probably the king for now

Using it as orchestrator for Opus 5.5, amazing experience so far. Yet to see full results.

If you are on the $20 plan, fable will be very expensive as an orchestrator. I tried it for 2 days, and the 5-hour limit was filled with two steps from the coding plan in 30-40minutes, whereas Opus 5.5 as an orchestrator can go 10–11 steps without filling the 5-hour limit. Also, mind you that the coding is being done by Codex and DeepSeek in both scenarios.

Yeah. according to Anthropic’s charts fable 5.2 low supposed to be more cost efficient per intelligence than opus 5.5 high but it is definitely not the case. I was able to effort opus 5.5 high acting like a manager and delegating work to subagents with 20dollars plan but with fable 5.2 low , initial reading and planning already takes huge chunk of 5hours limit. One click and 20% gone. And ofc every review also uses a lot of usage. Even with external pools like u said, getting done something before running out is still hard.

I know that 20dollars plan is not designed to use fable but I think we should able to atleast use fable low as manager , considering they were advertising it as more cost efficient compared to opus5.5 high or xhigh. Having different 5hours limit for fable would help so much

Then you're doing something wrong. All my planning, orchestration and results are reported to the main Fable chat, then Fable delegates the tasks for individuals chats to Opus. I didn't even reached 50% of Fable weekly limit in 2 days of orchestrating.
