DeepSeek 對比 ChatGPT
低成本的模型 API，對上最知名的助理。以下是你需要權衡的取捨。
我們的結論
如果你大量透過 API 呼叫模型，且每個 token 的成本最為重要，請選擇 DeepSeek。如果你想要一個無需設定、可直接使用的應用程式，請選擇 ChatGPT。對非技術團隊而言，ChatGPT 是較實用的選擇；DeepSeek 則適合建置自己工作流程的開發人員。在將商業資料送到任何一方之前，請先檢閱各供應商的資料條款。

常見問題
Why would a small business use DeepSeek instead of ChatGPT?
DeepSeek's API pricing is substantially lower per token, which matters if you're calling a model programmatically at volume. ChatGPT is the better choice for a polished, ready-to-use consumer app that needs no setup.
Is DeepSeek as capable as ChatGPT?
On several published benchmarks DeepSeek's frontier models are competitive with comparable OpenAI models, though the two differ task by task. See the AI benchmarks page on this site for dated, unaltered scores rather than a general claim.
