🦙 Llama3.1-8b-vision-audio Model Card

Model Details

This repository contains a version of the LLaVA model that supports image and audio input from the Llama 3.1-8B foundation model using the PKU-Alignment/align-anything library.

• Developed by: the PKU-Alignment Team.
• Model Type: An auto-regressive language model based on the transformer architecture.
• License: Non-commercial license.
• Fine-tuned from model: meta-llama/Llama 3.1-8B.
