Hippocratic AI Unveils Polaris 6 Ultra, the First Healthcare Model With Bedside Intuition, Built on Real-Life Experience, With Lower Pricing

Larger model brings new advancements to healthcare AI: Reads the patient and plans its next sentence while speaking, more realistic voice with clinical hearing. Ran 7.4-trillion-parameter safety constellation 1.3 times faster than its predecessor

MENLO PARK, Calif., Nov. 2, 2026 /PRNewswire/ -- Hippocratic AI today announced Polaris 6 Ultra, a new generation of its healthcare language model that delivers six upgrades to how an AI care agent listens, thinks, and speaks. Polaris 6 Ultra is the first healthcare model with what the company calls bedside intuition: the ability to read a patient's emotional state, think mid-speech and decide what to say next in the same breath, without a pause the patient can hear.

"In healthcare, you don't get credit for reminding a patient. You get credit for the action they take," said Munjal Shah, Co-Founder and CEO of Hippocratic AI. "Polaris 6.0 was built from more than 323 million patient conversations, making it the only truly experienced frontier model for healthcare able to operate safely and autonomously to drive patient outcomes. That experience shows. Polaris 6.0 handles the healthcare edge cases of real life, it now has more human-like common sense and pacing, and it delivers the kind of empathy that persuades patients."

General-purpose models aren't built to address healthcare edge cases, or handle the realities of patient care. Traditional LLMs expect clean audio, reason before they speak, know only what is written down, read every line in one tone, and get slower as they get smarter. That doesn't work for healthcare.

"Everyone building voice AI for healthcare trades off model size for latency: speech-to-speech models are fast and shallow, reasoning models are capable and slow," said Subhabrata Mukherjee, Co-Founder and Chief Science Officer. "We refused that choice. We took the largest model that could be made safe and rebuilt the entire stack for voice, from the GPU numerics to the breath in the synthesized voice. Then, with full-parameter reinforcement learning at frontier scale, we gave Polaris 6 not just safety but common sense, intuition, and the warmth and realism of an experienced clinician."

With increased EHR integration and new flexible pricing, Polaris can now meet the needs of any healthcare client. Polaris 6.0 ships as Ultra (full constellation, all 31 supervisors, for clinical patient-facing conversations), Pro (sub-clinical workloads), Flash (high volume, subclinical), and Nano [administrative use cases], so customers can match coverage and speed to their specific needs.

Polaris 6 Ultra closes all six gaps at once:

Across generations, the clinician-measured safety of the Polaris constellation has held at its ceiling since Polaris 4; with the latest constellation, the minor-harm rate in clinician output testing retains 0.00%. What has moved is the part patients feel: how natural, how perceptive, and how fast the agent is. Polaris 6 Ultra ships under the same criterion as every Polaris release: clinically tested, validated by licensed clinicians, and governed under human oversight before it reaches a patient.
