Strengths and tradeoffs
What each tool does well, and the limitations to keep in mind.
Pros
- Strongest academic credentials in compression with NeurIPS and EMNLP publications
- Four-person founding team from EPFL reduces single-founder risk
- Open-source Context Gateway creates community adoption funnel
