DeepSeek V4-Pro

Deprecated

DeepSeekFrontierOpen source

Preview-series sparse MoE flagship with a one-million-token context window and 1.6T total / 49B active parameters. DEPRECATED 2026-09-14: from 04:00 UTC all `deepseek-v4-pro` requests route to DeepSeek-V4.1-Flash, billed at V4.1-Flash rates, and will continue to until V4.1-Pro launches. The id still answers, so this is a redirect rather than a retirement.
