DeepSeek officially launched the V4-Flash API in public beta, featuring massively upgraded Agent capabilities, native Responses API support, and Codex adaptation.

Third-party benchmarks reveal that V4-Flash ties Gemini 3.6 Flash on the intelligence index but is 30x cheaper for output ($0.28 vs $7.50 per million tokens). With open weights and extreme cost-efficiency, it challenges the premium pricing of closed-source models.
