Pricing sourced from Kimi K2.5 · Last verified March 2026
Kimi K2.5 is an open-source, multimodal AI model developed by Moonshot AI and officially released on January 27, 2026. It can understand and generate text, code, and visual content from text, image, and video inputs. The model is designed for real-world execution rather than single-task assistance, supporting coding, document processing, research, and complex agent-based workflows. Moonshot AI focuses on building advanced AI models that help people work faster across many industries.
Yes, Kimi K2.5 offers a free tier with daily usage limits on queries, Agent Swarm runs, and file processing. Paid plans are available for higher usage caps, priority access, and more powerful agent-based workflows like Agent Swarm. You can access the free tier through the Kimi website, mobile app, or developer API. The Pro subscription is priced at approximately ¥59 RMB/month (~$8 USD/month), which is significantly cheaper than competing services like ChatGPT Plus or Claude Pro at $20/month each. API pricing follows a per-token model with rates starting at ¥12 RMB per million tokens (~$1.65 USD/M tokens) for shorter context windows, scaling up for longer contexts.
Kimi Agent Swarm is a multi-agent system where Kimi K2.5 self-directs up to 100 specialized AI sub-agents working in parallel, each responsible for a specific role such as research, coding, or reasoning. Use it when a task is too large or complex for a single agent — ideal for large-scale research, long-form writing, and batch operations like downloading or processing many files at once. Moonshot AI claims that Agent Swarm reduces execution time by up to 4.5× on long-horizon workflows, though this figure is based on the company's internal benchmarks. It is best suited for projects where different parts of the work can run independently in parallel.
Kimi K2.5 is released as an open-source AI model. According to Moonshot AI, model weights and code are publicly available on Hugging Face (under the moonshotai organization) and the official MoonshotAI GitHub repository, so developers and researchers can explore the architecture, build new solutions, and experiment openly. This is a key differentiator from closed competitors like GPT-4 or Claude. Self-hosting is possible for teams with sufficient compute, while the hosted product on kimi.com remains the easiest path for most users. Users should verify the specific license terms on the repository before commercial use.
Kimi K2.5 represents a qualitative shift from earlier Kimi models by moving from single-task assistance to real-world execution. It natively understands text, images, and video — enabling visual-to-code workflows — and introduces Agent Swarm for coordinating complex, long-horizon tasks. As a result, it produces complete work outputs such as documents, spreadsheets, slides, websites, and in-depth research reports, and scales to large multi-step projects executed in parallel. Earlier Kimi versions focused more narrowly on chat and reasoning.
