Artificial Analysis measured DeepSeek V4 Flash 0731 at 50 on its Intelligence Index, a 10-point jump over the April 2026 V4 Flash despite identical architecture and identical pricing, putting the Flash tier 6 points ahead of DeepSeek V4 Pro and 1 point behind GPT-5.6 Luna at max effort (51). At $0.06 per 1M tokens against GLM-5.2 (max) at $0.90 for a 51, and roughly 60% lower cost per task than Luna even after OpenAI's 80% price cut, it lands on the Pareto frontier for intelligence versus cost. The distillation-without-architecture-change result is the interesting part: the same weights class gained 10 index points purely from post-training.
