TL;DR: DeepSeek is the free-and-cheap reasoning pick — its chat app costs nothing and its API is a fraction of rivals’ prices (V4-Flash at $0.14 per million input tokens). Gemini is the full Google stack — a capable free tier, Google AI Pro at $19.99/month, deep integration with Gmail, Docs and Search, and top-tier multimodal skills across text, images, audio and video. Pay nothing and reason hard? DeepSeek. Live inside Google and want one assistant everywhere? Gemini.
Bottom line: On raw value DeepSeek is almost unbeatable. On ecosystem, polish and where your data sits, Gemini is the safer default for most people.

Why do people choose DeepSeek?
Price, then reasoning. DeepSeek made its name by delivering reasoning quality that embarrassed models costing ten times more, and its current rate card keeps that story alive: V4-Pro API output costs under a dollar per million tokens, with automatic caching discounting repeat context to fractions of a cent. The consumer chat is simply free, with no $20/month tier to upsell you. Developers also get something Gemini cannot offer — open-weight models. If you can run the model yourself, your prompts never leave your building, which turns DeepSeek’s biggest caveat (a hosted service based in China, with the data-residency questions that raises) into a non-issue.
Why do people choose Gemini?
Because it is already where their stuff is. Gemini sits inside Gmail, Docs, Drive, Maps and Android, reads the files you actually own, and handles video and audio as first-class inputs — drop in a meeting recording or a long video and ask questions about it. The free tier is generous enough for everyday use, Google AI Pro at $19.99/month raises limits and unlocks the strongest models and research tools, and businesses can buy it through Workspace with the data protections their compliance teams expect. Its flagship models pair a 1M-token context with strong multimodal reasoning, so long-document and media-heavy work is its home turf.
Which should you pick?
Pick DeepSeek if cost is the deciding factor, you want strong reasoning and coding help without a subscription, or you are a developer who will call the API — or self-host the open weights — and control your own data.
Pick Gemini if you live in Google apps, work with images, audio or video rather than plain text, need a supported business plan, or handle information your employer would not want sent to a Chinese-hosted consumer app.
Our verdict: For personal, non-sensitive use, DeepSeek’s free tier is the best deal in AI right now, and its API is the budget default for builders. For daily-driver assistant duties inside a Google life — and for almost any workplace — Gemini is worth its $19.99.
Frequently asked questions
Is DeepSeek better than Gemini?
At reasoning per dollar, DeepSeek leads — its API costs a small fraction of Gemini’s and its chat is free. Gemini is better at multimodal work, product polish and Google integration, and offers proper business plans.
Is DeepSeek really free?
The chat app and website are free to use. Developers pay only API usage, which starts at $0.14 per million input tokens on V4-Flash. Self-hosting the open-weight models costs only your own hardware.
How much is Google AI Pro?
$19.99/month in the US, with a free Gemini tier below it and AI Ultra plans starting at $99.99/month above it for the highest limits and newest features.
Is it safe to use DeepSeek for work documents?
That depends on your employer’s rules. DeepSeek is a China-based service, and many regulated organizations restrict sending company data to it. The self-hosted open-weight route avoids the issue; otherwise, Gemini through Workspace is the compliant default.
