DeepSeek
A completely free AI chat app, backed by cheap open-weight models you can also self-host
What it is
DeepSeek is the free AI chat app and API from the Chinese lab of the same name, built on its open-weight V4 family of models. The consumer chat at chat.deepseek.com has no Plus or Pro paywall at all: everything is free, with fair-use throttling as the only limit. The API is priced far below OpenAI and Anthropic, and the underlying V4 Flash and V4 Pro weights are released under MIT license for anyone who wants to self-host.

What you get free vs paid
Verdict
Pros
- The consumer chat app is entirely free, with no Plus or Pro tier gating features behind a paywall
- V4 Flash ranks in the top 10 of the Artificial Analysis Intelligence Index while costing $0.14 per million input tokens on the API
- New API sign-ups get a 5-million-token grant (about $8.40 of usage) valid for 30 days
- V4 Flash and V4 Pro weights are released under MIT license, so you can self-host instead of depending on DeepSeek's servers
Cons
- No paid tier means no way to skip the queue during peak hours, when "Server Busy" messages show up
- Servers and the company are based in China, which is a real consideration for anyone with data residency requirements
- The consumer app doesn't include native image generation
- DeepSeek has drawn security scrutiny after researchers documented a hacker using it with almost no human input to run real attacks
Hard to beat on price for both casual chat and API use, but the lack of any paid skip-the-line option means peak-hour throttling is the real cost of using it for free.
