Pros & cons

Our analysis

Pros

  • Free GPT-4o mini with no signup barrier
  • Image input, DALL-E 3, file uploads, browsing
  • Persistent memory and Advanced Voice Mode

Cons

  • Top models (GPT-4o, o1) need Plus
  • API billed per token separately
  • Desktop-focused interface

What users say

ChatGPT is widely used as a general-purpose AI interface, with a free tier that lowers the barrier to entry through GPT-4o mini access without requiring a sign-up. A frequently noted strength is its breadth of capabilities, including image input, DALL-E 3 image generation, document uploads, web browsing, and a real-time voice mode. A common limitation is that the most capable models require a Plus subscription, and API usage is billed separately on a per-token basis.
