## Model Card for Firefly-Qwen1.5 |
|
|
|
[firefly-qwen1.5-en-7b](https://huggingface.co/YeungNLP/firefly-qwen1.5-en-7b) and [firefly-qwen1.5-en-7b-dpo-v0.1](https://huggingface.co/YeungNLP/firefly-qwen1.5-en-7b-dpo-v0.1) are trained based on [Qwen1.5-7B](https://huggingface.co/Qwen/Qwen1.5-7B) to act as a helpful and harmless AI assistant. |
|
We use [Firefly](https://github.com/yangjianxin1/Firefly) to train our models on **a single V100 GPU** with QLoRA. |
|
firefly-qwen1.5-en-7b is fine-tuned based on Qwen1.5-7B with English instruction data, and firefly-qwen1.5-en-7b-dpo-v0.1 is trained with [Direct Preference Optimization (DPO)](https://arxiv.org/abs/2305.18290) based on firefly-qwen1.5-en-7b. |
|
|
|
Our models outperform official [Qwen1.5-7B-Chat](https://huggingface.co/Qwen/Qwen1.5-7B-Chat), [Gemma-7B-it](https://huggingface.co/google/gemma-7b-it), [Zephyr-7B-Beta](https://huggingface.co/HuggingFaceH4/zephyr-7b-beta) on [Open LLM Leaderboard](https://huggingface.co/spaces/HuggingFaceH4/open_llm_leaderboard). |

|
|
|
Although our models are trained with English data, you can also try to chat with models in Chinese because Qwen1.5 is also good at Chinese. But we have not evaluated |
|
the performance in Chinese yet. |
|
|
|
We advise you to install transformers>=4.37.0. |
|
|
|
## Performance |
|
We evaluate our models on [Open LLM Leaderboard](https://huggingface.co/spaces/HuggingFaceH4/open_llm_leaderboard), they achieve good performance. |

|
## Usage |
|
The chat templates of our chat models are the same as Official Qwen1.5-7B-Chat: |
|
```text |
|
<|im_start|>system |
|
You are a helpful assistant.<|im_end|> |
|
<|im_start|>user |
|
hello, who are you?<|im_end|> |
|
<|im_start|>assistant |
|
I am a AI program developed by Firefly<|im_end|> |
|
``` |
|
|
|
You can use script to inference in [Firefly](https://github.com/yangjianxin1/Firefly/blob/master/script/chat/chat.py). |
|
|
|
You can also use the following code: |
|
```python |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
import torch |
|
|
|
model_name_or_path = "YeungNLP/firefly-qwen1.5-en-7b" |
|
model = AutoModelForCausalLM.from_pretrained( |
|
model_name_or_path, |
|
trust_remote_code=True, |
|
low_cpu_mem_usage=True, |
|
torch_dtype=torch.float16, |
|
device_map='auto', |
|
) |
|
tokenizer = AutoTokenizer.from_pretrained(model_name_or_path) |
|
|
|
prompt = "Compose an engaging travel blog post about a recent trip to Hawaii, highlighting cultural experiences and must-see attractions. " |
|
messages = [ |
|
{"role": "system", "content": "You are a helpful assistant."}, |
|
{"role": "user", "content": prompt} |
|
] |
|
text = tokenizer.apply_chat_template( |
|
messages, |
|
tokenize=False, |
|
add_generation_prompt=True |
|
) |
|
model_inputs = tokenizer([text], return_tensors="pt").to('cuda') |
|
|
|
generated_ids = model.generate( |
|
model_inputs.input_ids, |
|
max_new_tokens=1500, |
|
top_p = 0.9, |
|
temperature = 0.35, |
|
repetition_penalty = 1.0, |
|
eos_token_id=tokenizer.encode('<|im_end|>', add_special_tokens=False) |
|
) |
|
generated_ids = [ |
|
output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids) |
|
] |
|
|
|
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0] |
|
print(response) |
|
``` |
|
|
|
