DeepSeek V4 Models Released Under MIT License, Widening Open Model Access

DeepSeek released V4 model variants on April 24, 2026 through open API infrastructure under MIT License terms. The dual-variant approach—V4-Pro for maximum capability and V4-Flash for low-latency deployment—targets different enterprise scenarios. Unlike competitors' more restrictive licensing, MIT terms allow full deployment flexibility. Models incorporate hybrid attention and three-tier reasoning architecture. The licensing choice lowers barriers to adoption and evaluation cycles.
