Which is all to say that I think the reason they went from Opus 3 to Opus 4 is because there was no bigger model to fine tune Opus 3.5 with.
And I would expect Opus 4 to be much the same.
- jascha_eng 1y agoBut sonnet 4.5 outperforms opus 4 on most benchmarks and tasks that can't be all that's to it
- sharkjacobs 1y agothat's not all there is to it, but I think that "the rest of it" is just additional fine tuning. Benchmarks are good fixed targets for fine tuning, and I think that Sonnet gets significantly more fine tuning than Opus. Sonnet has more users, which is a strategic reason to focus on it, and it's less expensive to fine tune, if API costs of the two models are an indicator.
