Pros & Cons
DeepSeek Chat
- Free chat interface with no cost for casual conversational use
- Genuinely competitive API pricing, especially during off-peak hours
- Free 5-million-token API grant for new signups, no credit card required
- Peak/off-peak pricing structure requires understanding UTC time zones to optimize costs
- Higher-capability V4-Pro model costs significantly more than the Flash tier
- API pricing structure is more complex to model than a flat per-token rate
ChatGPT
- Largest user base and ecosystem of any AI assistant, with the most third-party integrations
- Genuinely broad capability across writing, coding, research, and file analysis
- 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
