Introduction to DeepSeek-V4
DeepSeek-V4 is a significant improvement over its predecessors, offering a million-token context that agents can utilize. The real innovation lies in its design for efficient large context length support, making it an ideal candidate for agentic tasks. This is particularly useful for tasks that require a long tool-use trajectory, such as SWE-bench tasks, multi-step browse sessions, or terminal sessions with hundreds of commands.
Architectural Innovations
DeepSeek-V4’s architectural innovations mark a shift from basic chat toward multi-turn, long-context inference and agentic systems. The model’s design enables efficient large context length support, allowing it to handle large amounts of text more effectively. This is achieved through the use of a bfloat16 KV cache for prefill and partially token-wise fp8 for decode.
