Model Overview

v2ray/Llama-3-70B is a 70 billion parameter instruction-tuned large language model developed by Meta, released as part of the Llama 3 family. It is built on an optimized transformer architecture and incorporates Grouped-Query Attention (GQA) for enhanced inference scalability. The model was pretrained on over 15 trillion tokens of publicly available data, with a knowledge cutoff of December 2023, and further fine-tuned with over 10 million human-annotated examples.

Key Capabilities

• Optimized for Dialogue: Specifically instruction-tuned for assistant-like chat applications, outperforming many open-source chat models on industry benchmarks.
• Strong Performance: Demonstrates significant improvements over Llama 2 70B across various benchmarks, including MMLU (82.0 vs 52.9), HumanEval (81.7 vs 25.6), and GSM-8K (93.0 vs 57.5).
• Robust Safety Measures: Developed with a focus on helpfulness and safety, incorporating supervised fine-tuning (SFT) and reinforcement learning with human feedback (RLHF) to align with human preferences. Meta also provides resources like Llama Guard 2 and Code Shield for responsible deployment.
• 8K Context Length: Supports an 8192-token context window, suitable for handling moderately long conversations and documents.

Good For

• Commercial and Research Use: Intended for a wide range of applications in English-speaking contexts.
• Assistant-like Chatbots: Excels in dialogue-based scenarios due to its instruction-tuned nature.
• Code Generation: Shows strong performance in coding benchmarks like HumanEval.
• General Language Generation: Can be adapted for various natural language generation tasks, especially the pretrained variants.
