02Pricing compared
DeepSeek is cheaper to start: its web and mobile chatbot is free, and the pricing details list 5 million free API tokens at signup. The API has no monthly subscription; you pay per token. Rates vary by model and time: deepseek-flash input is listed at $0.15 per million tokens off-peak and $0.30 at peak, while output is $0.60 and $1.20. Kimi also has a free tier, but it excludes Kimi Code and limits projects, storage and tasks. Plus costs $19 monthly or $180 upfront annually ($15 a month). Pro costs $39 monthly or $372 annually ($31 a month). Kimi paid subscribers can buy extra usage, with a $10 minimum recharge. DeepSeek’s listed API rates are not a flat estimate of your bill: usage and peak-hour rates affect the total.
03Features and depth
DeepSeek’s edge is model access and developer control. Its published models include V3 and R1, with R1 trained using reinforcement learning for reasoning. The homepage describes a 671B-parameter Mixture-of-Experts model with 37B activated per token, plus Multi-Head Latent Attention to reduce key-value cache overhead. The API supports function calling, JSON output and context caching; the published pricing details list a 1-million-token context window and up to 384,000 output tokens. Developers can also self-host distilled Qwen- and Llama-based models from 1.5B to 70B parameters.
Kimi is broader as a work surface. Its listed tools include million-token context, multi-step web research with cited reports, document synthesis, coding and image parsing. Agent Swarm can coordinate parallel agents for tasks such as creating slides, spreadsheets and websites, but it is a Pro feature. Kimi Code is listed on Plus and Pro, not Free. Choose DeepSeek for open-weight models and API building blocks; choose Kimi when research and office-style agent tasks matter more than self-hosting.
04Ease of use and learning curve
For casual use, DeepSeek has a free web and mobile chatbot, so there is no paid plan to choose first. The published pricing details list no consumer usage cap or seat limit, but that is not a promise of unlimited access. Developers will need to work with a metered API and account for model, token and peak-hour rates.
Kimi packages chat, research, documents and agent tools in one workspace. Its Free tier has explicit limits: one parallel Agent task, two scheduled tasks, two widget tasks, two projects and 500MB of storage. Kimi Code is unavailable there. Paid plans raise some limits and add tools, so users need to compare those caps against their workflow before upgrading.
