ChatGPT

- Custom GPTs allow tailoring the assistant to specific repeated tasks
- Frequent model updates keep it competitive on raw capability
- Free tier has usage limits and access to a lower-tier model than paid plans
- Can produce confident-sounding but incorrect information, especially without browsing enabled
- Breadth can mean less depth than a tool purpose-built for one specific workflow
- Data usage and training policies require attention for sensitive or regulated work
