Pros & Cons
DeepSeek
Pros

Cons

- General writing quality is good but still trails Claude and ChatGPT for nuanced English prose
- Service availability has been spotty — major outages hit during the January 2025 hype wave
- No image generation capability — text-only output
- Limited ecosystem: no plugins, no app marketplace, minimal third-party integrations
Replika
