DeepSeek releases R2 reasoning model under an open-weight license

DeepSeek published R2 with open weights and accompanying technical notes focused on reasoning performance and inference efficiency. Early developer response centered on whether the release can pressure the closed-model leaders on cost and transparency at the same time.

Why It Matters

R2 reinforces the idea that important reasoning gains do not have to stay inside closed commercial systems.
