Ist Claude besser als DeepSeek? Die kurze Antwort
Claude has a documented Free plan, fixed monthly paid plans ($20 Pro) and published privacy terms, so it is the clearer choice for everyday chat use. DeepSeek is mainly documented as a developer API billed per 1M tokens, with OpenAI- and Anthropic-format endpoints and a 1M-token context. We could not confirm the DeepSeek chat app's free status, plans or privacy terms, so we cannot compare the two chat apps on price or data handling. Pick Claude for a known chat experience; pick DeepSeek if you want to pay per token through an API.

Häufig gestellte Fragen
Is DeepSeek cheaper than Claude?
For API use, yes: DeepSeek's API is billed per 1M tokens (deepseek-flash input $0.15 off-peak, $0.30 peak), while Claude's chat plans are flat monthly fees. Claude's API is also per token, for example Sonnet 5.5 at $2 input and $10 output per 1M tokens. We could not confirm DeepSeek chat app pricing.
Is the DeepSeek chat app free?
Unconfirmed: we could not verify whether the DeepSeek chat app is free. The chat site blocked automated access during our check on 2026-10-05, so its free status and plans are unverified. Claude has a Free plan with usage limits.
Can I use the Claude API with a Claude Pro subscription?
No. Claude's paid chat subscription does not include API access; the API is billed separately per token through the Claude Platform. DeepSeek's API is likewise a separate usage-priced service.
Does Claude or DeepSeek handle my data better?
Claude documents its data terms and DeepSeek's are unverified: Free, Pro and Max chats may be used for training unless you opt out, and Team and Enterprise do not train by default. DeepSeek's training use, retention and commercial-use terms were not verified, so we cannot rate it.
