DeepSeek V4 Lands With a 1.6-Trillion-Parameter Open-Weight Model — and Pricing That Undercuts Every Frontier API
DeepSeek previewed two new models on Thursday: V4 Flash (284B parameters, 13B active) and V4 Pro (1.6T parameters, 49B active). Both are mixture-of-experts with 1M-token context windows, and V4 Pro is now the largest open-weight model publicly available. Pricing — $0.14/$0.28 per million tokens for Flash, $0.145/$3.48 for Pro — undercuts GPT-5.4 and Gemini 3.1 Pro by an order of magnitude on input.
