- 9 million+ patient oncology database is one of the most comprehensive real-world oncology datasets available for pharmaceutical research
- FDA-accepted real-world evidence from multiple regulatory submissions provides unmatched regulatory validation
- NLP curation of clinical notes extracts structured data inaccessible through structured EHR data alone
- Roche ownership provides stability and pharmaceutical partnership pipeline
- $0.24/min audio output pricing accumulates quickly for high-volume voice applications
- WebSocket architecture requires different implementation approach than standard REST API calls
- Limited to GPT-4o — no model flexibility for latency vs cost trade-offs
- Roche ownership creates potential conflict of interest concerns for pharmaceutical competitors as data partners
- Real-world evidence database access requires partnership agreements limiting accessibility
