First impressions: - Very fast, easily beats GPT 5.5/Opus 4.8/GLM 5.2 because of higher t/s (around 90?) and very high token efficiency - Very good price, no contest vs GPT and Opus which are very overpriced if you pay API costs, and probably cheaper than GLM 5.2 when you take into account the token efficiency. - Will take quite a while to get a feel for how smart it is, but it's definitely good, I'd say in the same…
The fact that it is more token efficient will itself lead it to be smarter since the context will be smaller for the same task. However, in opus models, you'll have built internal correlations like "if it did X it will usually do Y" which may not be true here, since grok 4.5 may have done X purely due to the smaller context size, but can't do Y cos it wasn't RLd on that pattern enough. So it will be a unique experience as far as opus tier models go.
