Editorial excerpt
DeepSeek V4 Pro (Max)
AI-assisted, editorially reviewed
DeepSeek V4 Pro (Max) is published here because it has sourced SWE-Bench Pro evidence and a sourced DeepSeek V4 Pro model record.
DeepSeek V4 Pro (Max) is included in the coding leaderboard because current public sources attach it to SWE-Bench Pro, LiveCodeBench, and related coding-agent benchmarks. Treat the row as benchmark evidence first; regulated and sensitive deployments should review DeepSeek policy, hosting, and data controls before use.
