Meditron3-8B-GGUF

QuantFactory/Meditron3-8B-GGUF

This is quantized version of OpenMeditron/Meditron3-8B created using llama.cpp

Original Model Card

Model Card: Llama-3.1 Meditron-3[8B]

Model Type: Large Language Model (LLM)

Specialization: Medicine

Focus: General purpose including limited resource and humanitarian settings

Description: Meditron is a suite of large language models specialized in clinical medicine. The models are co-designed with a diverse range of expert clinicians and humanitarian practitioners. Its training emphasizes equitable representation, contextual diversity, and actionable real-world evidence-based guidelines. We make a particular effort to represent limited-resource and humanitarian settings, neglected populations, and diseases. This release is trained on Llama-3.1[8B] base model and has the nomenclature Llama-3.1 Meditron-3[8B].

Model details

• Developed by: OpenMeditron intiative
• Model type: Causal decoder-only transformer language model
• Language(s): English (mainly)
• Finetuned from model: Llama-3.1-8B
• Input: Text only
• Output: Text only
• Status: This is a static model trained on an offline dataset. Future versions of the tuned models will be released as we enhance model's performance.

Uses

Meditron-3 is a research-only model to study and evaluate the potential of LLMs in enhancing clinical decision-making and access to evidence-based medical information.

Direct Use

Meditron-3 is a research-only model. It is not validated for medical use (see disclaimer below).

Downstream Use

Meditron-3 is a suite of foundation models that have NOT been fine-tuned or instruction-tuned. However, these models can be adapted to specific downstream tasks or applications using techniques such as Reinforcement Learning from Human Feedback (RLHF) or Direct Preference Optimization (DPO). In our evaluation of the models, we have used two different methods for downstream question-answering tasks:

1. In-context learning with k demonstrations added to the prompt.
2. Model fine-tuning for Q&A tasks using specific training datasets.

Training Data

This new data mixture comprises expert-curated publicly available data and combines various sources:

• Clinical Guidelines: a dataset of internationally-recognized clinical practice guidelines from various healthcare-related sources across the world, including hospitals and international organizations.
• Peer-Reviewed Medical Publications: full-text medical articles.
• Synthetic Differential Diagnoses: synthetic conversation like data for differential diagnosis.
• Replay Data: general domain pretraining data sampled from multiple state of the art pretraining and instruction tuning.
• LLM-enhanced Medical MCQ: medical multiple-choice questions enriched with LLMs.

Additional information about the datasets will be included in the Meditron-3 publication.

Evaluation

Evaluation results for the Llama[3.1]-Meditron-3[8B] are coming soon!

We evaluated Meditron on medical multiple-choice questions using lm-harness for reproducibility. While MCQs are valuable for assessing exam-like performance, they fall short of capturing the model's real-world utility, especially in terms of contextual adaptation in under-represented settings. Medicine is not multiple choice and we need to go beyond accuracy to assess finer-grained issues like empathy, alignment to local guidelines, structure, completeness and safety. To address this, we have developed a platform to collect feedback directly from experts to continuously adapt to the changing contexts of clinical practice.

Paper

The Meditron-3 publication is currently in progress and will be released at a later date.
