Kimi

Kimi is an AI assistant developed by Moonshot AI, powered by the Kimi K2.5 model — a 1 trillion parameter multimodal mixture-of-experts architecture released in January 2026. Accessible via web, iOS, and Android, Kimi supports ultra-long context windows, autonomous agentic task execution, and structured document creation across slides, spreadsheets, websites, and research reports. With over 36 million monthly active users globally, it offers a free tier with daily usage limits and paid subscription plans for heavier workloads.
