Model Card for Model ID

This is a medicine-focussed mistral fine tuned using keivalya/MedQuad-MedicalQnADataset

Model Details

Model Description

Trying to get better at medical Q & A

  • Developed by: Tonic
  • Shared by [optional]: Tonic
  • Model type: Mistral Fine-Tune
  • Language(s) (NLP): English
  • License: MIT2.0
  • Finetuned from model [optional]: mistralai/Mistral-7B-v0.1

Model Sources [optional]

Uses

This model can be used the same way you normally use mistral

Direct Use

This model can do better in medical question and answer scenarios.

Downstream Use [optional]

This model is intended to be further fine tuned.

Recommendations

  • Do Not Use As Is
  • Fine Tune This Model Further
  • For Educational Purposes Only
  • Benchmark your model usage
  • Evaluate the model before use

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.

How to Get Started with the Model

Use the code below to get started with the model.
