DeepSeek · 2026-07-31
DeepSeek-V4-Flash-0731 is the official July 31, 2026 release of DeepSeek-V4-Flash, superseding the April preview after a retrained post-training pipeline focused on coding, agents, reasoning, and tool use. It keeps the preview's marketed 284B-total/13B-activated MoE design with a 1M-token context and Non-Think, Think High, and Think Max modes; its published checkpoint config matches the preview's architecture (43 layers, 4096 hidden size, 64 attention heads, 129280 vocabulary). Its weights are released under the MIT license.
