On narrow domains, it is very common for small models to match or outperform larger ones at a fraction of the parameter count.

For example in language, this is called the “curse of multilinguality”. Small models that handle a single translation direction can easily outperform big ones that try to handle them all.

In any case, for most tasks the question is not “how many tasks can this model kind of do well” but “given time/cost constraints, what is the maximum level of quality we can achieve”. And for that, small models are usually very competitive.

I think the context here is that small models run locally, not rented from a cloud.

Yes small models are and will be useful for lots of stuff for several reasons.

But the idea they’d be better than a bigger model is cope, you’re pretty much always better off running the biggest one you can bring to bear within your constraints.

Fable 5 is actually a lousy writer. Opus 4.6 is the best for writing and prose assessment. Gemini 3 is smarter at reading comprehension but tends to be more unstable in judgement.
