DeepSeek vs ChatGPT (2026): access, pricing, API and data optionsDeepSeek 对比 ChatGPT（2026）：可用性、价格、API 与数据选项
DeepSeek is a Chinese AI lab whose chat app and API compete with OpenAI's ChatGPT. This page sticks to what the official pages say as of the check date — no benchmark claims of our own.
以下内容只引用官方页面（核查日期见页尾），不做我们自己的跑分结论。
| DeepSeek | ChatGPT | |
|---|---|---|
| Sign-in | Official help center lists Google and email sign-in. | Free plan available to everyone; paid plans purchasable with any major credit card. |
| Consumer plans | Chat app on web and mobile (official Android app on Google Play). | Free, Go, Plus, Pro, Business and Enterprise. Business: $25/seat/month billed monthly or $20 billed annually. |
| API pricing (per 1M tokens) | deepseek-flash: $0.30 input (cache miss) / $1.20 output at peak; off-peak rates are half. deepseek-v4-pro: $1.32 / $3.96 at peak. | See OpenAI's official API pricing page (not reproduced here). |
| Context window (API) | 1M tokens (deepseek-flash). | Varies by model and plan; ChatGPT Plus lists a 256K reasoning context window. |
| Open weights | Yes — DeepSeek-V4.1-Flash repository and weights are MIT-licensed on Hugging Face. | ChatGPT is a hosted service; you can't download its models. |
| Where it can run / data residency | Besides DeepSeek's own API, DeepSeek models are listed on Alibaba Cloud Model Studio in US (Virginia) and Germany (Frankfurt) regions, and on third-party inference providers via Hugging Face. MIT weights also allow self-hosting. | ChatGPT Enterprise offers data residency in 10 regions (incl. US, EU, UK); Business, Plus and Free do not. |
Which should you pick?怎么选
- If cost per token and the option to self-host matter most, DeepSeek's MIT-licensed weights and low API prices are the main draw.
- If you need an all-in-one assistant with enterprise controls (SSO, data residency), ChatGPT's Business/Enterprise plans document those features.
- Western teams worried about sending data to a China-hosted API can run DeepSeek models through US/EU cloud regions or self-host — check each provider's terms.
