**LongAlign** is the first full recipe for LLM alignment on long context. We propose the **LongAlign-10k** dataset, containing 10,000 long instruction data of 8k-64k in length. We investigate on trianing strategies, namely **packing (with loss weighting) and sorted batching**, which are all implemented in our code. For real-world long context evaluation, we introduce **LongBench-Chat** that evaluate the instruction-following capability on queries of 10k-100k length. |

|
|
|
答： |
|
``` |
|
Chat prompt template for LongAlign-7B-64k and LongAlign-13B-64k: |
|
```text |
|
[INST]Hi![/INST]Hello! What can I assist you today? |
|
|
|
[INST]What should I do if I can't sleep at night?[/INST] |
|
``` |
|
ChatGLM3-6B-128k uses the same prompt template as [ChatGLM3-6B](https://huggingface.co/THUDM/chatglm3-6b). |

|
A simple demo for deployment of the model: |
|
```python |
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
import torch |
|
tokenizer = AutoTokenizer.from_pretrained("THUDM/LongAlign-6B-64k", trust_remote_code=True) |
|
model = AutoModelForCausalLM.from_pretrained("THUDM/LongAlign-6B-64k", torch_dtype=torch.bfloat16, trust_remote_code=True, device_map="auto") |
|
model = model.eval() |
|
query = open("assets/paper.txt").read() + "\n\nPlease summarize the paper." |
|
response, history = model.chat(tokenizer, query, history=[], max_new_tokens=512, temperature=1) |
|
print(response) |
|
``` |
