Pros & Cons
DeepSeek
Pros

- Transparent chain-of-thought reasoning shows you exactly how the model reaches conclusions
- Active open-source community building tools, quantizations, and fine-tunes around the models
Cons

- Limited ecosystem: no plugins, no app marketplace, minimal third-party integrations

Cons
- Requires Python developers with NLP and machine learning expertise — not for non-technical teams
- Training a production-quality assistant takes 2-3 months of iterative development
- Enterprise pricing starts around $25K/year and isn't published transparently
