Strategy: Tiered Clinical AI Pipeline
Healthcare AI works best with a tiered pipeline — route routine tasks to budget models and complex clinical decisions to premium models with higher accuracy.
This tiered approach saves 92% compared to using GPT-5 for all encounters, while maintaining clinical accuracy where it matters most.
Healthcare-Specific Considerations
- HIPAA compliance: AI APIs don't automatically make your app HIPAA compliant. You need a BAA with your provider, proper encryption, and access controls. Always de-identify PHI before sending to cloud APIs.
- Clinical accuracy: Medical documentation requires high precision. Budget models work for administrative tasks (coding, scheduling), but clinical decisions benefit from premium models with stronger reasoning.
- Input-heavy workload: Clinical notes, lab results, and patient histories are long inputs with shorter outputs. Input price typically accounts for 60-80% of healthcare AI costs.
- Real-time vs batch: Patient-facing applications (chatbots, messaging) need low-latency models. Clinical documentation can be processed asynchronously, enabling cheaper batch processing.
- Specialty considerations: Radiology, pathology, and genomics may require specialized models or fine-tuning. General-purpose LLMs work well for documentation, coding, and patient communication.
