Pros and cons
ChatGPT
Chatbots · freemium
Pros
- ✓Widest feature set of any AI assistant — voice, vision, image gen, video, code, browsing, and agents in one app
- ✓o3 and o4-mini reasoning models are top-tier for complex problem-solving
- ✓Operator agent and Deep Research add genuinely useful autonomous capabilities
- ✓Free tier now includes limited GPT-4o access, not just the mini model
Cons
- ×Pro plan at $200/mo is hard to justify unless you need heavy o3 or Operator usage
- ×Writing quality has fallen behind Claude for nuanced, long-form content
- ×Custom GPT ecosystem is broad but quality varies wildly — lots of low-effort entries
- ×Privacy concerns remain: conversations used for training unless you opt out
