DeepSeek
Free chat / API from ~$0.14 per million tokens
ChatGPT Plus
$20 per mo
DeepSeek offers free, capable chat and an extremely cheap developer API, but lacks the polish and tooling of ChatGPT. ChatGPT Plus ($20) is the versatile, well-rounded assistant with image generation and a huge ecosystem. DeepSeek wins on price; ChatGPT wins on features and polish.
Pick DeepSeek if you want strong, free AI chat for everyday reasoning and coding, or the cheapest capable API for building.
Pick ChatGPT Plus if you want the most versatile, polished assistant with image generation, voice, and a broad ecosystem.
DeepSeek and ChatGPT both answer questions, write, and code, but they sit at opposite ends of the price spectrum. DeepSeek made waves with strong reasoning and coding models offered free in its chat app and at an extremely low API cost, which makes it hugely popular with budget-conscious users and developers. ChatGPT Plus is the well-rounded standard: image generation, voice mode, custom GPTs, and the largest ecosystem of tools and integrations.
On price, DeepSeek's consumer chat is free with no paid tier, and its API is among the cheapest available, while ChatGPT Plus is $20 a month. The choice is mostly free, capable AI and a cheap API (DeepSeek) versus the most versatile, polished assistant (ChatGPT).
