Yes, this is already accounted for in many benchmarks, but without deep context of the problem type, the top line pricing is the best starting point.

In my own experience, Fable is more token efficient than opus 4.8 with a higher likelihood of completing tasks correctly or at least with minimal corrective work. Opus regularly struggled to gather the correct context and reason effectively about what it had gathered.

GPT-5.6-sol crushes fable in speed and token efficiency and is clearly superior across many tasks that matter for me.

I also find all models from anthropic after opus 4.6 to suffer from the same ai slop language that long plagued OpenAI and seems to have been reduced drastically in 5.6
