DeepSeek V4 Pro 0813 goes GA as a 1.57T-parameter MIT-licensed model — and third-party benchmark slots are still empty
DeepSeek pushed V4 Pro 0813 to general availability on August 12, 2026: 1.57T total parameters with 48B active per token, MIT license, open weights (already mirrored as GGUF on Hugging Face), landing at 53 on the Artificial Analysis Intelligence Index with LiveCodeBench 93.50, MMLU Pro 87.50, and SWE-bench Verified 80.60. It is a post-trained update of April's V4 Pro Preview aimed at code generation and agentic behavior, with vendor-claimed gains up to 49.9 percentage points. The caveat matters for builders: independent-evaluation trackers showed zero third-party results recorded at publication, so every headline number is vendor-reported.
