[Beijing, China][founded 2023][backed by Alibaba; Tencent]www.moonshot.ai

Founded in March 2023 and headquartered in Beijing, Moonshot AI develops the Kimi series of foundation models with backing from Alibaba and Tencent. Its Kimi Chat assistant, launched in October 2023, was one of China's first consumer long-context LLM products, and the K2 line (July 2025 onward) shipped 1T-parameter open-weight MoE models under a modified MIT licence. Kimi K3, released in July 2026, is a 2.8T-parameter open-weight multimodal model with a 1M-token context.
