About

DeepSeek-V4-Pro (build 0813, GA August 2026) is the flagship of DeepSeek's V4 family: a 1.6T-total-parameter MoE model with 49B active parameters per token and a 1M-token context window, released under an MIT license.

The newer DeepSeek-V4.1-Flash (Sept 10, 2026) is the fast tier — cheaper and, per DeepSeek, matching or beating Pro on agentic coding — also MIT-licensed.

Trust score — 9/10

/10 trustVerified

MIT-licensed open weights, published pricing with clear peak/off-peak rules, and independent AA Index corroboration make this one of the most auditable entries. Caveats: the peak/off-peak pricing adds budgeting complexity, benchmark transparency is thinner than Anthropic/OpenAI's, and previously advertised permanent discounts were revoked once (Aug 2026).
