About DeepSeek-V4-Pro

DeepSeek-V4-Pro, released April 24, 2026 alongside the lighter DeepSeek-V4-Flash, is DeepSeek's frontier open-weight flagship. It scored 90.1% on GPQA Diamond and 93.5% on LiveCodeBench — the top published competitive-coding score on this tracker — with 83.4% on BrowseComp for agentic web research.

The V4 generation extends DeepSeek's consistent playbook: frontier-adjacent capability, open weights, and dramatically lower cost than closed rivals. V4-Pro competes directly with the strongest proprietary models of spring 2026 while remaining freely downloadable, continuing the open-weights pressure the lab began with V3 and R1.
