DeepSeek V4 Pro exits preview as V4-Pro-0813 with major coding benchmark gains
DeepSeek
DeepSeek quietly shipped DeepSeek-V4-Pro-0813 as the general-availability release of its V4 Pro flagship on August 12, 2026, ending a nearly four-month preview. The 1.6T-parameter MoE model (49B active) keeps its 1M-token context and shows large jumps in agentic coding benchmarks versus the preview, including SWE-bench Verified at 80.6%, LiveCodeBench at 93.5%, and Terminal-Bench 2.1 rising from 72.1 to 87.9.
Why it matters
It signals DeepSeek is closing the gap with top-tier closed models on agentic coding tasks while holding aggressive pricing, intensifying the China vs. US frontier-model price and capability race.
Importance: 3/5
Notable release: flagship model exits preview with large agentic-coding benchmark jumps, confirmed by official pricing docs plus two independent media sources.
