This was released 6 days ago. The dust hasn't settled yet, and Mistral Small 4 was released earlier. Even if Deepseek V4-flash turns out to crush it, there was a period where it was Pareto competitive. None of the countries I named (i.e. no country that isn't China/US/Mistral) have had a Pareto competitive model at any point in time.
