Following the release of [LLM360/AmberChat](https://huggingface.co/LLM360/AmberChat) and [LLM360/AmberSafe](https://huggingface.co/LLM360/AmberSafe) in December 2023, CrystalChat is the next and most performant chat model released under LLM360. CrystalChat is trained on a carefully selected mix publicly available language and code datasets. As always, the training data, training code, and metrics are publicly available. ## About LLM360 LLM360 is an initiative for comprehensive and fully open-sourced LLMs, where all training details, model checkpoints, intermediate results, and additional analyses are made available to the community. Our goal is to advance the field by inviting the community to deepen the understanding of LLMs together. As the first step of the project LLM360, we release all intermediate model checkpoints, our fully-prepared pre-training dataset, all source code and configurations, and training details. We are committed to continually pushing the boundaries of LLMs through this open-source effort. Get access now at [LLM360 site](https://www.llm360.ai/) # Instruction Tuning Training **CrystalChat** is using the last **CrystalCoder** checkpoint of phase2 ([CrystalCoder_phase2_checkpoint_214387](https://huggingface.co/LLM360/CrystalCoder/tree/CrystalCoder_phase2_checkpoint_214387)) as the initialization checkpoint. We then finetune the model using the dataset mentioned below. We also performed the same finetuning on the last **CrystalCoder** checkpoint of phase3 ([CrystalCoder_phase3_checkpoint_027728](https://huggingface.co/LLM360/CrystalCoder/tree/CrystalCoder_phase3_checkpoint_027728)). The phase2 and phase3 finetuning results are very similar, but phase2 finetuning exhibits slightly better performance on the English language benchmarks. We choose the phase2 finetuning result as the final model for **CrystalChat**. # Instruction Tuning Data The fine-tuning data is a mix of publicly available language and code datasets, plus a orginally created dataset called **WebAlpaca** on HTML coding instructions. The WebAlpaca dataset is created by us and is used as part of our instruction tuning training data. We will release the WebAlpaca dataset in a separate repository soon. The summary of the fine-tuning data is as follows: | Subset | #Tokens | Avg. #Q | Avg. Query Len | Avg. #R | Avg.

List special tokens used in the instruction tuning: ``` bos: eos: system_start: <|sys_start|> system_end: <|sys_end|> user_start: <|im_start|> user_end: <|im_end|> ``` The instruction format is as follows: ``` <|sys_start|> system prompt <|sys_end|> <|im_start|> first user utterance <|im_end|> first model response <|im_start|> next user utterance <|im_end|> next model response ``` # Reproducing the Results We will release the training code and the training data soon. Our training code is based on [Megatron-LM](https://github.com/NVIDIA/Megatron-LM), with some modifications to support our training data format and Maximal Update Parametrization (μP). # CrystalChat Performance | Model | Trained Tokens | Avg. of Avg. | Language Avg. | Coding Avg. | ARC | HellaSwag | MMLU (5-shot) | GSM8K | Winogrande(5-shot) | TruthfulQA | HumanEval (pass@1) | MBPP (pass@1) | |:------------------------:|:--------------:|:------------:|:-------------:|:-----------:|:-----:|:---------:|:-------------:|:-----:|:------------------:|:----------:|:------------------:|:-------------:| | CrystalChat 7B | 1.275T | 44.96 | 53.29 | 36.62 | 51.71 | 76.12 | 53.22 | 28.05 | 70.64 | 47.29 | 34.12 | 39.11 | | Mistral-7B-Instruct-v0.1 | - | 44.34 | 54.86 | 30.62 | 58.05 | 75.71 | 55.56 | 32.00 | 74.27 | 55.90 | 29.27 | 31.96 | | CodeLlama-7b-Instruct | 2.5T | 40.91 | 45.29 | 36.52 | 43.35 | 66.14 | 42.75 | 15.92 | 64.33 | 39.23 | 34.12 | 38.91 | | Llama-2-7b-Chat | 2T | 34.11 | 52.86 | 15.35 | 53.07 | 78.39 | 48.42 | 18.88 | 73.09 | 45.30 | 13.26 | 17.43 | | AmberChat 7B | 1.25T | - | 44.76 | - | 42.83 | 74.03 | 38.88 | 5.31 | 66.77 | 40.72 | - | - | | Combined Language and Coding Ability | |------------------------------------------------| arc | Performance on Standard Benchmarks | |------------------------------------------------| std-bench | Perforamnce on Language Benchmarks | |---------------------------------------------------------| arc ## Model Description - **Model type:** Language model with the same architecture as LLaMA-7B - **Language(s) (NLP):** English - **License:** Apache 2.0 - **Resources for more information:** - [Training Code](https://github.com/LLM360/crystalcoder-train) - [Data Preparation](https://github.com/LLM360/crystalcoder-data-prep) - [Metrics](https://github.com/LLM360/Analysis360) - [Fully processed CrystalCoder pretraining data](https://huggingface.co/datasets/LLM360/CrystalCoderDatasets) # Loading CrystalChat ```python import torch from transformers import AutoModelForCausalLM, AutoTokenizer device = "cuda:0" if torch.cuda.is_available() else "cpu" tokenizer = AutoTokenizer.from_pretrained("LLM360/CrystalChat", trust_remote_code=True) model = AutoModelForCausalLM.from_pretrained("LLM360/CrystalChat", trust_remote_code=True).to(device) prompt = ' <|sys_start|> You are an AI assistant.

The training data is known and made available [here](https://huggingface.co/datasets/LLM360/CrystalCoderDatasets). It primarily consists of SlimPajama, StarCoder, and WebCrawl dataset. # Citation **BibTeX:** ```bibtex @misc{liu2023llm360, title={LLM360: Towards Fully Transparent Open-Source LLMs}, author={Zhengzhong Liu and Aurick Qiao and Willie Neiswanger and Hongyi Wang and Bowen Tan and Tianhua Tao and Junbo Li and Yuqi Wang and Suqi Sun and Omkar Pangarkar and Richard Fan and Yi Gu and Victor Miller and Yonghao Zhuang and Guowei He and Haonan Li and Fajri Koto and Liping Tang and Nikhil Ranjan and Zhiqiang Shen and Xuguang Ren and Roberto Iriondo and Cun Mu and Zhiting Hu and Mark Schulze and Preslav Nakov and Tim Baldwin and Eric P.
