DeekSeek V4 is Here!
Key Improvements
-Attention mechanism: a novel architecture with token-dimension compression, and DSA (DeepSeek Sparse Attention) reducing computation costs plus VRAM consumption for longer context
-Agent capabilities: optimized for mainstream Al agent frameworks (ClaudeCode, Openclaw, and Opencode)
-Public knowledge: V4-Pro performs exceptionally well on public knowledge benchmark, second most closely to top closed-source models like Gemini-pro-3.1 -Reasoning capability: V4-Pro obtains scores comparable to the top-tier closed-source models in mathematics, STEM, and competitive programming benchmarks -Inference intensity: reasoning mode now supports the reasoning_effort parameter
(high/max)
V4-Pro: Performance first. Establishes a highlevel performance in agentic coding for open-source models. official benchmarks indicate that the user experience thrives above Sonnet 4.5 and comes close to Opus 4.6 (non-reasoning mode).
V4-Flash: on smaller featuer counts than V3 and with active weights. Response time is faster than V4-Pro API and lower cost, reasoning ability similar to V4-Pro and performance close to Pro on simple agent tasks
you can test out DeepSeek V4 on zenmux now and it'scurrently free
