Kimi K3: Moonshot AI Open-Sources Its AI Model as Markets React
On July 27, 2026, Moonshot AI, a Beijing-based artificial intelligence company, open-sourced the weights of its Kimi K3 model. Developers can now freely download, customize, and host the model themselves. The model's presentation and comparative test results triggered a sell-off in AI-related stocks. Like DeepSeek in early 2025, Kimi K3 demonstrates that Chinese AI companies can compete with U.S. leaders OpenAI and Anthropic while using fewer resources, intensifying American concerns about Chinese technological catch-up.
