At a glance
DeepSeek is the cheaper option ($20.00/mo less), both offer a free plan, ChatGPT rates slightly higher.
Our take
This isn't a like-for-like fight. DeepSeek's web chat is free with fair-use throttling at peak hours, and its API is priced in cents per million tokens (V4.1 Flash from $0.15 input off-peak). Developers watching costs will find it hard to beat on price.
ChatGPT Plus at $20/mo is a polished consumer product: image generation, voice conversations, file analysis and a large ecosystem. DeepSeek's chat is text-focused and can slow down at busy times.
For many people the answer is both: use DeepSeek free for everyday text questions, and pay for ChatGPT only if you need its extra features. If you're building on an API, DeepSeek's pricing is the headline, but check the peak/off-peak windows.
- Choose DeepSeek if you want a free text assistant or the cheapest API for building products.
- Choose ChatGPT if you want images, voice and file analysis in one polished app.
Watch out: DeepSeek's API prices double during peak hours (01:00-04:00 and 06:00-10:00 UTC, Monday to Friday). Batch jobs are cheaper off-peak.
