DeepSeek ships V4 Pro to GA at 1.6T parameters as valuation hits $74B

V4-Pro-0813 is now generally available on OpenRouter's model page and DeepSeek's API docs, retaining its aggressive preview pricing that ranks it second only to Anthropic on OpenRouter token consumption. The 1.6T-parameter MoE system with a 1M-token context targets long-context reasoning and coding at a fraction of Western frontier pricing.

DeepSeek also launched a refreshed V4-Flash-0731 with just 284 billion parameters that reportedly rivals Anthropic's Opus 4.8, and is standing up a dedicated team to compete in agentic coding against Meta's Muse Code, OpenAI's Codex, and Google. The $74 billion valuation—up 40% from June—funds compute infrastructure and research.

Competitively, DeepSeek's $0.87/M output pricing is a central force in the week's price war, undercutting Grok 4.6 ($6/M) and pressuring OpenAI, which cut prices up to 80% and freed GPT-5.6 Luna. Its rise reflects the broader Chinese open-weight surge alongside Alibaba's Qwen3.8-Max.

On r/DeepSeek, users reported strong results running V4 Flash across eight agent harnesses ('Deepseek and Pi are match made in heaven,' 307 upvotes) and speculated V4 Pro would be 'insanely good' enough to 'break their compute.' Skeptics question whether the preview pricing is sustainable at GA scale. Watch how V4 Pro benchmarks against Grok 4.6 and GPT-5.6 Sol and whether the agentic-coding team ships a distinct product.
