What each tool does
ChatGPT is OpenAI's chat assistant for questions, writing, research and everyday productivity. It can also generate images and take on agent-style tasks, and it is available in the browser and on mobile.
DeepSeek is an AI company that offers a chat assistant on the web and in a mobile app, with features such as a deep thinking mode and smart search. It also releases several of its models as open source, including DeepSeek-V4 and DeepSeek-R1, and developers can connect through its API platform.
Key differences
- Openness: DeepSeek publishes open-source models; ChatGPT is a closed product you use through OpenAI's apps.
- Developer focus: DeepSeek highlights its API and open models for builders; ChatGPT is aimed mainly at end users.
- Output types: ChatGPT lists image generation; DeepSeek describes built-in visual understanding in its latest release rather than image creation.
- Special modes: DeepSeek offers deep thinking and smart search; ChatGPT lists agent-style tasks.
Which should you choose?
Choose ChatGPT if you want a familiar, broad assistant for study, freelancing and content work, including quick images, without thinking about models or APIs.
Choose DeepSeek if you are a developer or technically curious user who values open-source models, wants to reason through harder problems with deep thinking mode or plans to build on an API.
You can start chatting on either for free. Paid use, such as higher limits or API usage, is typically billed online, so users in Pakistan should check card payment options and check the pricing page for current plans.
Can you use both?
Yes. A common pattern is to use ChatGPT for everyday writing and images while trying DeepSeek for step-by-step reasoning or for testing its open models in your own projects.
