June 30: One major research article — DeepSeek V4 and DSpark, the open-source efficiency breakthrough with 1.6T MoE, 1M context, and 85% faster inference via speculative decoding.
DeepSeek released the V4 model family (1.6T MoE Pro, 284B MoE Flash) with 1M-token context and the DSpark speculative decoding framework on June 27, 2026. DSpark accelerates per-user generation 60-85% over MTP-1 without new hardware or retraining, while V4-Pro-Max achieves 93.5% on LiveCodeBench and 3206 Codeforces rating — the best open-source results to date. The full DeepSpec toolkit is MIT-licensed and supports Qwen3 and Gemma target models.
