DeepSeek vs Perplexity: Features, Pricing and User Reviews 2026
What are DeepSeek and Perplexity?
DeepSeek is an AI company from China that builds smart chat and reasoning models. You can use it for free through its website or mobile app to ask questions, get help with writing, or solve coding problems. Instead of just giving short answers, DeepSeek can think through hard problems step by step, which makes it strong at math, coding, and reasoning tasks.
Developers can also use DeepSeek through an API that works the same way as OpenAI and Anthropic tools, so it is easy to plug into existing apps. DeepSeek also shares its model files openly, so anyone can download them, run them on their own computers, or build new tools on top of them.
Perplexity is a tool that answers your questions using live information from the web. Instead of showing you a list of links like normal search engines, it reads current pages and gives you a clear, written answer with the sources listed right below it.
It uses its own model called Sonar along with other well known AI models, so answers stay accurate and up to date. You can also ask follow up questions, and it remembers what you asked before, so the conversation feels natural.
There is a free plan for everyday use, plus paid Pro and Max plans that unlock stronger models, file uploads, and extra tools like Perplexity Computer and the Comet browser.

For developers, DeepSeek offers an API that is billed by usage, based on the number of tokens processed.
DeepSeek-V4-Flash: Costs $0.14 per 1 million input tokens, $0.0028 per 1 million tokens on a cache hit, and $0.28 per 1 million output tokens.
