What it does
Free AI chatbot (web, iOS, Android) from Chinese lab DeepSeek, offering its flagship reasoning models, currently featuring a V4 preview, at no cost.
Strong fit
Pick it for a fully free, capable reasoning chatbot with no subscription needed, or for its very cheap developer API.
Poor fit
Avoid for sensitive/confidential data (China-based service, trains on inputs by default) or if you need image/video generation and rich voice features.
Limitations
No paid consumer tier to buy priority or higher limits; text-focused feature set; inputs used for model training unless you opt out; service can throttle at peak demand.
