DeepSeek V4 Pro 0813

DeepSeek V4 Pro 0813 is the general-availability checkpoint of DeepSeek V4 Pro, released around August 12-13, 2026. It keeps the April 2026 architecture, a 1.6T-parameter mixture-of-experts with 49B active per token, but was re-post-trained and repriced: GA pricing rose to $0.66 per million input tokens and $1.98 per million output tokens versus the promotional preview rates.

Weights are released under the MIT license on Hugging Face with a 1M-token context. Vendor-reported scores include 93.5% on LiveCodeBench, 80.6% on SWE-bench Verified, and 90.1% on GPQA Diamond, though independent contamination-resistant benchmarks show a wider gap to closed frontier models than DeepSeek's own numbers suggest.
