It suits people who want a strong chatbot without a subscription, and developers whose token bill matters more than any one benchmark. The catches are that DeepSeek publishes no message cap for the free app, and that API prices depend on the hour: seven weekday hours, 01:00 to 04:00 and 06:00 to 10:00 UTC, cost twice the rate of the rest of the week.
There is nothing to subscribe to. The app is free, and the API runs on a prepaid balance that does not expire and can be refunded on request, minus fees, with granted credit spent first. Flash costs under a quarter of Pro's price per uncached input token and about a seventh per cached one. Web search and page fetch called through the API have been billed per request since November 1, 2026.
