DeepSeek-V4-Pro-Max tops coding, reasoning benchmarks

DeepSeek has bridged the reasoning gap with top-tier closed models, proving that open-weights MoE architectures remain an efficient path to frontier performance. The "Think Max" reasoning mode enables significant inference-time compute scaling, while the 90% reduction in KV cache requirements via hybrid attention offers massive infrastructure wins for long-context deployments. Matching frontier models on agentic tasks makes DeepSeek a viable primary choice for autonomous developer tools.
