Opus 5.5 is in a different category than all those Chinese models - as long as anthropic allows it to work on your stuff (which is a thing now too).
While that is unquestionably going on, these models are legitimately innovative and stand on their own legs.
Of course, benchmarks don’t tell you how much it will cost on your workload.
GLM 5.3 was more expensive than Haiku and Sonnet 5.5 on a workload I was testing recently despite being much cheaper on the price sheet.
