Medichat-V2-Llama3-8B
This is a merge of pre-trained language models created using mergekit.
This model is particularly effective in structuring the unstructured clinical texts.
Model Composition and Features:
Base Model: The foundation of this model is based on "refuelai/Llama-3-Refueled," which itself is a refined version of the Llama3-8B model, renowned for its instruction-following capabilities and adaptability across various domains.
Merged Models:
- ruslanmv/ai-medical-model-32bit: A model fine-tuned specifically for answering technical medical questions, providing a solid base of medical knowledge.
- Locutusque/Llama-3-Hercules-5.0-8B: Known for its ability to follow complex instructions and handle conversational interactions effectively, especially in scientific and technical contexts.
This model was merged using the DARE TIES merge method using refuelai/Llama-3-Refueled as a base.

Based on the symptoms of dizziness, headache, and nausea, the differential diagnosis could include several conditions. Here are some possible causes:
1. Vestibular disorders: These can cause dizziness, vertigo, and nausea. Examples include benign paroxysmal positional vertigo (BPPV), labyrinthitis, and vestibular neuritis.
2. Migraine: Migraines can cause severe headaches, nausea, and dizziness. They can be triggered by various factors, such as stress, changes in sleep patterns, or certain foods.
3. Inner ear infections: Infections in the inner ear, such as labyrinthitis or otitis media, can cause dizziness, nausea, and headache.
4. Meniere's disease: This is a disorder of the inner ear that can cause episodes of vertigo, nausea, and hearing loss.
5. Motion sickness: This can occur when the body receives conflicting signals from the eyes, inner ear, and other sensory systems. It can cause dizziness, nausea, and headache.
6. Anxiety or panic attacks: Anxiety or panic attacks can cause dizziness, nausea, and headache.
7. Low blood sugar (hypoglycemia): Low blood sugar can cause dizziness, headache, and nausea.
8. Medication side effects: Certain medications, such as antibiotics, antihistamines, and antidepressants, can cause dizziness, headache, and nausea as side effects.
9. Stroke or transient ischemic attack (TIA): These can cause sudden onset of dizziness, headache, and nausea.
10. Brain tumor or other central nervous system disorders: Rarely, a brain tumor or other central nervous system disorder can cause dizziness, headache, and nausea.
It is essential to consult a healthcare professional for a proper evaluation and diagnosis. They will likely perform a physical examination, take a detailed medical history, and order appropriate tests to determine the underlying cause of the symptoms. Treatment will depend on the specific diagnosis and may include medications, lifestyle changes, or other interventions.
prompt = '''
A 52-year-old woman comes to the physician because of a 6-month history of generalized fatigue, low-grade fever, and a 10-kg (22-lb) weight loss. Physical examination shows generalized pallor and splenomegaly. Her hemoglobin concentration is 7.5 g/dL and leukocyte count is 41,800/mm3. Leukocyte alkaline phosphatase activity is low. Peripheral blood smear shows basophilia with myelocytes and metamyelocytes. Bone marrow biopsy shows cellular hyperplasia with proliferation of immature granulocytic cells. Which of the following mechanisms is most likely responsible for this patient's condition?
