DeepSeek pivots to open-source after price hikes, releasing V4 Pro and agent harness under MIT

DeepSeek open-sourced its agent harness (Cordis meta-framework) under MIT license and released V4 Pro as open-weight on Hugging Face under MIT, a strategic shift after raising API pricing up to 1,100% for V4 models. This move signals a bid to capture developer ecosystem and compete with Nvidia's open-source strategy. The open-weight release allows enterprises to run the model on their own infrastructure, potentially disrupting the closed-model market. A new thesis on DeepSeek reveals Liang Wenfeng's singular vision: betting on learning as the path to AGI, with open-source as a strategic bet on future dominance.
