Kimi Review: Features, Pricing & Alternatives
Moonshot AI's assistant for long documents, research and agent tasks, powered by its open Kimi models.
What is Kimi?
Kimi is the AI assistant from Moonshot AI, a Beijing startup founded in 2023 by Yang Zhilin and colleagues and backed by investors including Alibaba and Tencent. Kimi first became known for reading very long documents at a time when most chatbots could only handle short inputs. Today it is a full assistant for chat, research, coding and multi-step agent tasks, available on the web and in mobile apps.
Moonshot moves fast. It released the open-weight Kimi K2 model in July 2025, added the OK Computer agent and K2 Thinking later that year, and followed with K2.5 and K2.6 in 2026. In July 2026 it released Kimi K3, a 2.8-trillion-parameter open-weight model. Demand was so high that Moonshot temporarily paused new paid subscriptions days after launch to protect existing members.
What sets Kimi apart is its agent focus. Paid plans are measured in agent credits, and Kimi can split big jobs across an Agent Swarm of sub-agents that work in parallel to build websites, slides, spreadsheets and research reports. Because its models are open weights, developers can also run or fine-tune them outside Moonshot’s own apps.

Kimi vs alternatives
Kimi competes most directly with DeepSeek and Qwen Chat, two other Chinese assistants with open models. DeepSeek is simpler and cheaper, Qwen Chat is free with more media tools, and Kimi stands out for long-context reading and agent work. Manus and Genspark are the closest rivals for agent-style tasks that produce finished files.
Against ChatGPT and Claude, Kimi is competitive on research and agents but offers fewer integrations and raises data-residency questions for some businesses. See all best AI chatbot and assistant tools.
Our verdict: is Kimi worth it?
Kimi is one of the most capable assistants for long documents and agent tasks, and its open-weight models make it attractive to developers. Casual users can stay on the free plan, while power users should check whether paid sign-ups are open and compare credit costs before committing.
