Everything looked meh so far, until entered the visual recognition and reasoning chapter. That was very impressive. Very cool to see more vendors pushing towards models understanding images instead of just performing OCR.

The pricing in their subscription plan also look quite generous. https://platform.stepfun.com/step-plan

I just wish they put a little bit of energy on making their service usable for non-chinese users. At the moment, their website assumes I speak chinese and when I manually click on "en", the website dynamically translates parts into english, I experience this as half baked solution.
