Meta Llama 3 8B: An Overview

Meta Llama 3 8B is an 8 billion parameter instruction-tuned language model from Meta's Llama 3 family, designed for efficient and effective dialogue. It leverages an optimized transformer architecture, incorporating Grouped-Query Attention (GQA) for enhanced inference scalability. The model was trained on a vast dataset of over 15 trillion tokens from publicly available sources, with fine-tuning including over 10 million human-annotated examples, and supports an 8k token context length.

Key Capabilities

Enhanced Dialogue Performance: Optimized for assistant-like chat and dialogue use cases, showing significant improvements over previous Llama 2 models.
Strong Benchmark Results: Achieves 68.4 on MMLU, 34.2 on GPQA, 62.2 on HumanEval, and 79.6 on GSM-8K, indicating robust general reasoning, knowledge, and coding abilities.
Reduced False Refusals: Fine-tuned to be less prone to falsely refusing benign prompts compared to Llama 2, improving user experience.
Responsible AI Focus: Developed with extensive red teaming, adversarial evaluations, and safety mitigations, supported by tools like Llama Guard 2 and Code Shield.
