DeepSeek officially released DeepSeek-V4-Flash-0731 on July 31, 2026 — a 284B/13B MoE model with substantially enhanced agentic capabilities, MIT-licensed weights, 1M-token context, and API pricing at $0.14/M input tokens (99% cheaper than Claude Opus 4.8). Covers the architecture (CSA+HCA hybrid attention, mHC connections, Muon optimizer), DSpark speculative decoding, benchmark results across 9 agentic coding tasks, Deep Code CLI, Responses API/Codex integration, and the strategic implications for the global AI price war.
One major research article published: DeepSeek V4 Flash & Pro API migration deadline (July 24), hybrid attention architecture enabling 1M-token context at 10% KV cache, three-tier reasoning effort system, and unprecedented pricing that establishes a new price floor for frontier models.
DeepSeek's legacy API aliases (deepseek-chat, deepseek-reasoner) will be permanently deprecated on July 24, 2026 at 15:59 UTC. This article covers the mandatory migration to deepseek-v4-flash and deepseek-v4-pro, the hybrid attention architecture (CSA+HCA) that enables 1M-token context at 10% KV cache of V3.2, the three-tier reasoning effort system, and DeepSeek's unprecedented pricing that establishes a new price floor for frontier models.
