DeepSeek V4 Launches as Largest Open-Weight Model at 1 Trillion Parameters

DeepSeek released V4 in early March 2026, the largest openly available AI model to date at 1 trillion parameters. The model features a 1-million-token context window and native multimodal support spanning text, code, vision, and audio.

Fully Open Access

Unlike many large models that carry restrictive licenses, DeepSeek V4 is free to download, run, and modify with no commercial license required. This makes it the most capable model available for self-hosting and local deployment.

Industry Impact

The release puts pressure on proprietary model providers by narrowing the gap between open and closed models. For enterprises concerned about data privacy or vendor lock-in, DeepSeek V4 represents a viable alternative to hosted API services from OpenAI, Anthropic, and Google.
