More than a year after taking the AI world by storm, Chinese AI startup DeepSeek has unveiled two versions of its all-new large language model (LLM) called DeepSeek V4 Flash and DeepSeek V4 Pro.
Both the Flash and Pro models are open-weight models with context windows of over 1 million tokens each, which allows users to input large documents or entire codebases in prompts. The Pro model has a total of 1.6 trillion parameters (49 billion active), reportedly making it the biggest open-weight model available.
It outpaces Moonshot AI’s Kimi K 2.6 model (1.1 trillion parameters), MiniMax’s M1 (456 billion parameters), and more than doubles its predecessor, DeepSeek V3.2 (671 billion parameters).
The Flash model, on the other hand, is the smaller of the two with over 284 billion parameters (13 billion active). Both models have been released under research preview. Unlike many of its closed rival AI models, the V4 Flash and V4 Pro reportedly cannot be used to generate audio, video, and images as they support text outputs only.
