-## Model Details
-We introduce Llama3-ChatQA-2, which bridges the gap between open-source LLMs and leading proprietary models (e.g., GPT-4-Turbo) in long-context understanding and retrieval-augmented generation (RAG) capabilities. Llama3-ChatQA-2 is developed using an improved training recipe from [ChatQA-1.5 paper](https://arxiv.org/pdf/2401.10225), and it is built on top of [Llama-3 base model](https://huggingface.co/meta-llama/Meta-Llama-3-70B). Specifically, we continued training of Llama-3 base models to extend the context window from 8K to 128K tokens, along with a three-stage instruction tuning process to enhance the model’s instruction-following, RAG performance, and long-context understanding capabilities. Llama3-ChatQA-2 has two variants: Llama3-ChatQA-2-8B and Llama3-ChatQA-2-70B. Both models were originally trained using [Megatron-LM](https://github.com/NVIDIA/Megatron-LM), we converted the checkpoints to Hugging Face format. **For more information about ChatQA 2, check the [website](https://chatqa2-project.github.io/)!**

-## Overview of Benchmark Results
-<!-- Results in [ChatRAG Bench](https://huggingface.co/datasets/nvidia/ChatRAG-Bench) are as follows: -->
-We evaluate ChatQA 2 on short-context RAG benchmark (ChatRAG) (within 4K tokens), long context tasks from SCROLLS and LongBench (within 32K tokens), and ultra-long context tasks from In- finiteBench (beyond 100K tokens). Results are shown below.

-## Prompt Format
-**We highly recommend that you use the prompt format we provide, as follows:**
-### when context is available
-<pre>
-System: {System}
-{Context}
-User: {Question}
-Assistant: {Response}
-User: {Question}
-Assistant:
-</pre>
-### when context is not available
-<pre>
-System: {System}
-User: {Question}
-Assistant: {Response}
-User: {Question}
-Assistant:
-</pre>
-**The content of the system's turn (i.e., {System}) for both scenarios is as follows:**
-<pre>
-This is a chat between a user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions based on the context. The assistant should also indicate when the answer cannot be found in the context.
-</pre>
-**Note that our ChatQA-2 models are optimized for the capability with context, e.g., over documents or retrieved context.**
-## How to use
-### take the whole document as context
-This can be applied to the scenario where the whole document can be fitted into the model, so that there is no need to run retrieval over the document.
