DeepSeek-V4-Pro is the flagship model of the DeepSeek V4 series, released as a preview and open-sourced alongside its efficiency-tier sibling V4-Flash. It is positioned as the performance-first tier in the V4 lineup, designed to push agentic capability, world knowledge, and reasoning performance to levels competitive with leading closed-source models.

The model introduces a new attention mechanism that performs compression along the token dimension, combined with DeepSeek Sparse Attention (DSA). The design makes a 1M context window the default across all official DeepSeek services while substantially reducing compute and memory overhead compared with prior approaches.

DeepSeek-V4-Pro has been specifically adapted and optimized for mainstream agent products such as Claude Code, OpenClaw, OpenCode, and CodeBuddy. According to DeepSeek, V4-Pro reaches the top tier among open-source models on Agentic Coding benchmarks, and is currently used internally at DeepSeek as the default Agentic Coding model—with internal evaluation reports describing a usage experience above Sonnet 4.5 and delivery quality close to Opus 4.6 in non-thinking mode, while still trailing Opus 4.6 in thinking mode. On world knowledge, it leads open-source models and trails only Gemini-Pro-3.1; on math, STEM, and competitive coding, it delivers results on par with top closed-source models.

The model supports both thinking and non-thinking modes, with the thinking mode exposing a reasoning_effort parameter (high / max) for complex agent workflows. It is available via App, Web, and API through the OpenAI ChatCompletions and Anthropic interfaces, with weights open-sourced on Hugging Face and ModelScope._
