DeepSeek V4 is the next open-source LLM from China's DeepSeek, featuring 1M+ token contexts via Sparse Attention, Engram memory, and 40% cheaper inference.

When does DeepSeek V4 launch?

Expected around Lunar New Year, February 17, 2026 — codenamed MODEL1, it's a full architecture overhaul.

How does DeepSeek V4 beat previous models?

Massive context for codebases, stable training with mHC, and efficient KV cache — all open-weight, runnable on modest hardware.
