Opus is a larger and more expensive model. Presumably 3.5 Opus will be the best but it hasn't been released. 3.5 Sonnet is better than 3.0 Opus kind of like how a newer i5 midrange processor is faster and cheaper than an old high-end i7.

Makes me wonder if perhaps they do have 3.5 Opus trained, but that they're not releasing it because 3.5 Sonnet is already enough to beat the competition, and some combination of "don't want to contribute to an arms race" and "it has some scary capabilities they weren't sure were ready to publish yet".
