Moonshot AI

The Beijing model lab behind the Kimi assistant, founded in March 2023 by the Tsinghua- and Carnegie Mellon-trained researcher Yang Zhilin and named after Pink Floyd's The Dark Side of the Moon (reported). Moonshot first made its name in China with very long context windows (200,000 Chinese characters in October 2023, 2 million announced in March 2024) and an expensive consumer advertising campaign that bought users it could not keep. After DeepSeek's January 2025 releases took the Chinese consumer market from it, Moonshot cut its advertising, refocused on model quality and open weights, and released Kimi K2 (July 2025), a ~1-trillion-parameter open-weight model that made it one of the best-known Chinese labs among Western developers. In 2026 its fortunes turned sharply: Kimi K2.5 became the base model for Cursor's Composer 2, its valuation rose from ~$4.3bn (December 2025) to ~$35bn (July 2026) and a reported ~$50bn pre-money (August 2026), and it filed confidentially for a Hong Kong IPO in early September 2026 (reported). Alibaba was its largest outside shareholder from 2024 (reported); a long arbitration with investors in Yang's previous start-up is its main unresolved controversy.
