DELHI / NEW YORK – Fractal (www.fractal.ai), a global provider of artificial intelligence (AI) to Fortune 500® companies, today announced the launch of Vaidya 2.0, the next generation of its healthcare reasoning models available at Vaidya.ai. Debuting at the India AI Impact Summit 2026, Vaidya 2.0 scores 50.1 on HealthBench (hard), outperforming OpenAI’s GPT-5 and Google’s Gemini Pro 3 on this challenging benchmark.
Designed to power “Health Care Operating System” based workflows, Vaidya 2.0 bridges the gap between raw data and healthcare action. It is the first AI model in the world to achieve 50+ score on OpenAI’s HealthBench (hard) The model has been post-trained to deliver superior performance on a wide range of health care workflows.

Redefining the Healthcare Journey
Vaidya 2.0 significantly enhances model capabilities for enabling real-world healthcare use cases, including citizen facing use-cases such as:
- Emergency Assist: Rapid triage and decision support in critical windows.
- Symptom Checker: High-fidelity reasoning for citizen-facing wellness.
- Patient Journey Assist: End-to-end support from first symptom to treatment adherence.
Vaidya 2.0 models also demonstrate a significant performance on MedExpert benchmark and introduce new capabilities to support Doctor Assist. These capabilities combined with the Administrator Assist capabilities from OpenAI HealthBench (hard) Health Data Tasks enhances ability to cater to medical professionals.
Scaling for the India AI Mission
As a partner selected under the ₹10,300+ crore India AI Mission, Fractal is at the forefront of building India’s sovereign AI capabilities. Vaidya 2.0 represents the first of many verticalized foundation models designed to solve the unique challenges of the Global South – frugal, scalable, and impact-driven.
“India has built strong digital health foundations over the past decade – from ABHA health IDs to Ayushman Bharat and e-Sanjeevani. The next step is adding reliable reasoning intelligence to those systems,” said Srikanth Velamakanni, Co-founder, Group Chief Executive & Vice Chairman, Fractal. “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.”
“With Vaidya 2.0, we’ve moved from the knowledge-based foundation models to more advanced post-trained reasoning and agentic based healthcare models” added Suraj Amonkar, Chief AI Research & Platforms Officer, Fractal. “By ranking top globally, on the OpenAI HealthBench (hard) that focuses on realistic healthcare conversations and also showing leading performance on the MedExpert Benchmark that evaluates expert-level medical reasoning, 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.”
