# Nexusflow/Starling-LM-7B-beta AWQ |
|
|
|
## Model Summary |
|
|
|
- **Developed by:** Banghua Zhu * , Evan Frick * , Tianhao Wu * , Hanlin Zhu, Karthik Ganesan, Wei-Lin Chiang, Jian Zhang, and Jiantao Jiao. |
|
- **Model type:** Language Model finetuned with RLHF / RLAIF |
|
- **License:** Apache-2.0 license under the condition that the model is not used to compete with OpenAI |
|
- **Finetuned from model:** [Openchat-3.5-0106](https://huggingface.co/openchat/openchat-3.5-0106) (based on [Mistral-7B-v0.1](https://huggingface.co/mistralai/Mistral-7B-v0.1)) |
|
|
|
We introduce Starling-LM-7B-beta, an open large language model (LLM) trained by Reinforcement Learning from AI Feedback (RLAIF). Starling-LM-7B-beta is trained from [Openchat-3.5-0106](https://huggingface.co/openchat/openchat-3.5-0106) with our new reward model [Nexusflow/Starling-RM-34B](https://huggingface.co/Nexusflow/Starling-RM-34B) and policy optimization method [Fine-Tuning Language Models from Human Preferences (PPO)](https://arxiv.org/abs/1909.08593). |
|
Harnessing the power of our ranking dataset, [berkeley-nest/Nectar](https://huggingface.co/datasets/berkeley-nest/Nectar), our upgraded reward model, [Starling-RM-34B](https://huggingface.co/Nexusflow/Starling-RM-34B), and our new reward training and policy tuning pipeline, Starling-LM-7B-beta scores an improved 8.12 in MT Bench with GPT-4 as a judge. Stay tuned for our forthcoming code and paper, which will provide more details on the whole process. |

## How to use |
|
|
|
### Install the necessary packages |
|
|
|
```bash |
|
pip install --upgrade autoawq autoawq-kernels |
|
``` |
|
|
|
### Example Python code |
|
|
|
```python |
|
from awq import AutoAWQForCausalLM |
|
from transformers import AutoTokenizer, TextStreamer |
|
|
|
model_path = "solidrust/Starling-LM-7B-beta-AWQ" |
|
system_message = "You are Starling, incarnated as a powerful AI." |
|
|
|
# Load model |
|
model = AutoAWQForCausalLM.from_quantized(model_path, |
|
fuse_layers=True) |
|
tokenizer = AutoTokenizer.from_pretrained(model_path, |
|
trust_remote_code=True) |
|
streamer = TextStreamer(tokenizer, |
|
skip_prompt=True, |
|
skip_special_tokens=True) |
|
|
|
# Convert prompt to tokens |
|
prompt_template = """\ |
|
<|im_start|>system |
|
{system_message}<|im_end|> |
|
<|im_start|>user |
|
{prompt}<|im_end|> |
|
<|im_start|>assistant""" |
|
|
|
prompt = "You're standing on the surface of the Earth. "\ |
|
"You walk one mile south, one mile west and one mile north. "\ |
|
"You end up exactly where you started. Where are you?" |
|
|
|
tokens = tokenizer(prompt_template.format(system_message=system_message,prompt=prompt), |
|
return_tensors='pt').input_ids.cuda() |
|
|
|
# Generate output |
|
generation_output = model.generate(tokens, |
|
streamer=streamer, |
|
max_new_tokens=512) |
|
|
|
``` |
|
|
|
### About AWQ |
|
|
|
AWQ is an efficient, accurate and blazing-fast low-bit weight quantization method, currently supporting 4-bit quantization. Compared to GPTQ, it offers faster Transformers-based inference with equivalent or better quality compared to the most commonly used GPTQ settings. |
|
|
|
AWQ models are currently supported on Linux and Windows, with NVidia GPUs only. macOS users: please use GGUF models instead. |
|
|
|
It is supported by: |
|
|
|
- [Text Generation Webui](https://github.com/oobabooga/text-generation-webui) - using Loader: AutoAWQ |
|
- [vLLM](https://github.com/vllm-project/vllm) - version 0.2.2 or later for support for all model types. |
|
- [Hugging Face Text Generation Inference (TGI)](https://github.com/huggingface/text-generation-inference) |
|
- [Transformers](https://huggingface.co/docs/transformers) version 4.35.0 and later, from any code or client that supports Transformers |
|
- [AutoAWQ](https://github.com/casper-hansen/AutoAWQ) - for use from Python code |
|
|
|
## Prompt template: ChatML |
|
|
|
```plaintext |
|
<|im_start|>system |
|
{system_message}<|im_end|> |
|
<|im_start|>user |
|
{prompt}<|im_end|> |
|
<|im_start|>assistant |
|
``` |
