Moonshot AI Unveils Kimi K3, a 2.8 Trillion-Parameter Open-Source AI Model Challenging Western Rivals

Chinese startup Moonshot AI has launched Kimi K3, a new 2.8 trillion-parameter open-source model. Benchmarks suggest Kimi K3 is nearing the performance of cutting-edge models like Anthropic's Fable 5, while being more cost-effective. This release intensifies competition in the AI landscape and has contributed to a sell-off in Western AI and semiconductor stocks due to concerns about demand for proprietary models and associated hardware.
