"A single do-everything model in healthcare is a black box."
That's how Tal Amitay, VP of Engineering at Brook Health, describes monolithic healthcare AI systems.
Brook took a different approach.
Instead of one model handling everything, they built a multi-agent architecture where translation, risk scoring, behavioral coaching, and escalation workflows operate independently — with separate guardrails and evaluation layers.
Because in healthcare, one failure should not compromise the entire system.
Their deployment included:
→ input guardrails for emergencies, self-harm, and adversarial prompts
→ output controls preventing unsafe or biased responses
→ governance defined before deployment, not after
→ human escalation paths with full clinical context transfer
The result is not slower innovation.
It's safer iteration at production scale.
