DeepSeek's open-weights frontier family, previewed April 24, 2026. V4-Pro is 1.6T total / 49B active params; V4-Flash is 284B / 13B. 1M context standard. Weights on Hugging Face.
DeepSeek V4 is the open-weights frontier release of mid-2026, shipped in two mixture-of-experts variants: DeepSeek-V4-Pro at 1.6T total / 49B active parameters and DeepSeek-V4-Flash at 284B total / 13B active. A 1M token context window is now the default across all official DeepSeek services, and the weights are open-sourced on Hugging Face. The API supports both OpenAI ChatCompletions and Anthropic Messages formats, which makes it close to a drop-in swap in existing codebases, and the legacy `deepseek-chat` and `deepseek-reasoner` endpoints retire after July 24, 2026. For teams that want self-hostable, frontier-adjacent capability at a fraction of closed-model pricing, V4 is the current reference point.
