Fractal has launched Vaidya 2.0, the next generation of its healthcare reasoning models, designed to function as a healthcare operating system that bridges the gap between raw medical data and clinical action.

Suraj Amonkar, chief AI Research & Platforms officer, Fractal. "Vaidya 2.0 models demonstrate a health-operating system approach that is not only more comprehensive, but also more reliable and accurate across a wide variety of healthcare workflows."
From benchmarks to bedside
Scoring 50.1 on OpenAI's HealthBench (hard), Vaidya is the first AI model globally to cross the 50-point mark and outperform GPT-5 and Gemini Pro 3 on the benchmark.
It also demonstrated strong performance on the MedExpert benchmark, which evaluates expert-level medical reasoning.
The upgraded model significantly expands its real-world healthcare capabilities, supporting use cases such as:
- Emergency Assist: Rapid triage and decision support during critical windows
- Symptom Checker: Advanced reasoning for citizen-facing wellness queries
- Patient Journey Assist: End-to-end support from first symptom to treatment adherence
It also introduces enhanced Doctor Assist capabilities and builds on Administrator Assist features under HealthBench (hard) Health Data Tasks to support healthcare professionals.
Scaling under the India AI Mission
Fractal is a selected partner under India's ₹10,300+ crore India AI Mission, which aims to strengthen sovereign AI capabilities. Vaidya 2.0 is the first in a series of verticalised foundation models built to address large-scale healthcare delivery challenges in emerging markets.

Srikanth Velamakanni, co-founder, group chief executive & vice chairman, Fractal, said:"When you combine India's digital health infrastructure with reliable reasoning AI, you unlock a new operating model for public health. At India's population scale, intelligence must be accurate, transparent, and accountable. That is the problem Vaidya 2.0 is built to solve."
