DeepSeek-V4-Pro-Max landed in June 2026 benchmark roundups at 80.6% on SWE-bench Verified with downloadable MIT-licensed weights, keeping it inside the closed-frontier 80%+ cluster while remaining fully open. It reinforces that open-weight coding models are now viable for self-hosted agentic pipelines.
