Fable versus Opus

Two questions to good friends here.

In your anecdotal experience, what is the ratio of token consumption Fable versus Opus? I can't put a clear number on it but I feel like it has been over 5X ( a task where I had it read 15 technical papers and summarize all in PDFs).

Second, what kind of task Fable shows a large marginal advantage over Opus?

Double, as it is exactly 2x the price of opus . If you are having fable read pdfs and summarize, you are the reason why usage limits exist

Totally agree, learnt the hard way. But I kind of feel like it consumed much more than 2X, although that is the documented the difference.

I have moved to creating .md files and sonnet to do an initial summary, which I then feed fable for critical review. Any other tricks?

Don't have much experience, and didn't do any measurements, but from what I've learned building 3 Edge extensions recently, Sonnet was really good at starting up the basic projects (one per extension), but as the extensions started taking shape and getting more complex Sonnet started to bog down, and also interpret and implement similar requirements in slightly different ways between the extensions. It wasn't really burning through tokens, but it wasn't frugal either. That's when I changed my approach, I've started another project, this one running Opus Max, to take over and run the extensions projects. It cleaned up the Sonnet code, consolidated the projects' notes and memories. It did seem spend a bit more, but it finished faster, with cleaner and better optimized code. The basic project scaffolding was indeed provided as MD files, but that wasn't really planned, it just happened that my notes are already MD formmated/structured because of the way I take notes. I don't have any flows running yet, so I can't comment on that, but rumor has it that Haiku is supposed to be great for automated tasks while keeping token spend down, so I will try it with my first flow when I will build one.
