AI firm Fractal has built India's first medical LLM Vaidya. ai

AI firm Fractal has built India's first multimodal medical LLM Vaidya. ai, a general-purpose assistant meant to help users with diagnosis, treatment and medical advice.

Vaidya is fine-tuned using open-source base models which are 30-70 billion parameters in size and trained on 650k+ images and 200k+ text inputs capable of understanding Hindi, Kannada, Tamil, Telugu etc., co-founder and CEO Srikanth Velamakanni said.

“It's not even in the foreseeable future that we will have a situation where we don't need doctors and AI may tell you what to do. AI is far from that. The problem we are solving is very different. It's about aiding consumers in accessing healthcare information which is more reliable than any other sources of information,” he explained.


Along with Fractal’s existing product Qure. ai, which is a mature player in healthcare AI for detecting tuberculosis, lung cancer, heart failure and stroke, Vaidya.ai could become a one-of-its-kind enterprise solution.

But, it is currently Fractal’s AI research project instead of an enterprise product, Velamakanni said.

When asked about the accuracy of responses given by Vaidya, he said that the evaluations are done using PG NEET exam questions.

“PG NEET is the most competitive medical exam with 200,000 postgraduate doctors take every year. Fractal currently ranks at par with top 500 in that system with 83% accuracy,” he said.

Suraj Amonkar, Chief AI Research and Platforms Officer at Fractal said, "The development involved training models and frameworks using LLM and VLM architectures and validating the models on 20+ years of PG NEET/ PG Medical examination papers, among other metrics to measure how well the models performed. While it offers valuable insights and information, it always encourages users to consult healthcare professionals for medical advice."
