Llama 2 vs. Hippocratic AI

We are excited to unveil the latest version of our open-source large language model, which includes model weights and initial code for the pretrained and fine-tuned Llama language models, ranging from 7 billion to 70 billion parameters. The Llama 2 pretrained models have been crafted using a remarkable 2 trillion tokens and boast double the context length compared to the first iteration, Llama 1. Additionally, the fine-tuned models have been refined through the insights gained from over 1 million human annotations. Llama 2 showcases outstanding performance compared to various other open-source language models across a wide array of external benchmarks, particularly excelling in reasoning, coding abilities, proficiency, and knowledge assessments. For its training, Llama 2 leveraged publicly available online data sources, while the fine-tuned variant, Llama-2-chat, integrates publicly accessible instruction datasets alongside the extensive human annotations mentioned earlier. Our project is backed by a robust coalition of global stakeholders who are passionate about our open approach to AI, including companies that have offered valuable early feedback and are eager to collaborate with us on Llama 2. The enthusiasm surrounding Llama 2 not only highlights its advancements but also marks a significant transformation in the collaborative development and application of AI technologies. This collective effort underscores the potential for innovation that can emerge when the community comes together to share resources and insights.

Hippocratic AI stands as a groundbreaking innovation in the realm of artificial intelligence, outperforming GPT-4 in 105 out of 114 healthcare-related assessments and certifications. Remarkably, it surpassed GPT-4 by at least five percent on 74 of these certifications, with a margin of ten percent or more in 43 instances. Unlike many language models that draw from a wide array of internet resources—which may sometimes lead to the dissemination of incorrect information—Hippocratic AI is focused on obtaining evidence-based healthcare content through legitimate channels. To enhance the model’s efficacy and ensure safety, we are deploying a tailored Reinforcement Learning with Human Feedback approach that actively engages healthcare professionals in both training and validating the model before it reaches the public. This thorough methodology, referred to as RLHF-HP, ensures that Hippocratic AI will be introduced only after receiving endorsement from a considerable number of licensed healthcare experts, emphasizing patient safety and precision in its functionalities. This commitment to stringent validation not only distinguishes Hippocratic AI in the competitive landscape of AI healthcare solutions but also reinforces the trust that users can place in its capabilities. Ultimately, Hippocratic AI sets a new standard for reliability and effectiveness in the field of healthcare technology.
