How this price is scoped: DeepInfra lists two entries for this model: DeepSeek-V4-Flash-0731 at $0.06 input / $0.015 cached input / $0.18 output per 1M tokens, and the undated DeepSeek-V4-Flash at $0.09 / $0.018 / $0.18. The tracked figure is the 0731 entry: DeepInfra describes it as the official release of DeepSeek-V4-Flash that supersedes the preview, DeepSeek's own API moved deepseek-v4-flash to the 0731 version on 2026-07-31, and it is the cheaper of the two. Call it as deepseek-ai/DeepSeek-V4-Flash-0731; the undated name costs 50% more on input.
