How to use

This repository contains two versions of Meta-Llama-3-8B-Instruct, for use with transformers and with the original llama3 codebase.

Use with transformers

You can run conversational inference using the Transformers pipeline abstraction, or by leveraging the Auto classes with the generate() function. Let's see examples of both.

Training Data

Overview cyberAI is pretrained from dad1909/DSV that data related to software vulnerability codes. The fine-tuning data includes publicly available instruction and output datasets.

Data Freshness The pretraining data is continuously updated with new vulnerability codes.
