What each tool does
DeepSeek runs a chat assistant on the web and mobile, publishes several of its language models as open source and offers an API platform for developers. Features include a deep thinking mode and smart search.
Kimi is an AI assistant from a Chinese developer, positioned for productivity, research, business analysis and coding. It supports agent-style tasks where the assistant works through a job for you, and it has a mobile app. Public details are limited, so check the main site for its current feature list.
Key differences
- Positioning: DeepSeek is a model maker with a general assistant on top. Kimi presents itself as a work-focused helper for knowledge workers and students.
- Openness: DeepSeek releases open-source models and has a documented API platform. Kimi is described here as an assistant only.
- Task style: Kimi emphasises agent-style tasks and analysis. DeepSeek emphasises reasoning through its deep thinking mode and search.
- Information available: DeepSeek's offering is well described. Kimi's listing had limited detail, so expect to explore it yourself.
- Pricing: both are freemium. Kimi mentions membership for extra usage; check each pricing page for current plans.
Which should you choose?
Choose DeepSeek if you want a well-documented assistant with strong reasoning features, or you are a developer who wants open models and API access.
Choose Kimi if your work involves research, business analysis or multi-step tasks and you want an assistant that frames itself around getting that kind of work done.
Can you use both?
Yes. Since both have free ways to start, you can give the same research or coding task to each and compare. DeepSeek may suit reasoning-heavy questions, while Kimi may fit longer productivity tasks. Only consider paying in USD once one clearly saves you time.
