## Model Description
|
16 |
+
|
17 |
+
Nous-Yarn-Mistral-7b-128k is a state-of-the-art language model for long context, further pretrained on long context data for 1500 steps using the YaRN extension method.
|
18 |
+
It is an extension of [Mistral-7B-v0.1](https://huggingface.co/mistralai/Mistral-7B-v0.1) and supports a 128k token context window.
|
19 |
+
|
20 |
+
To use, pass `trust_remote_code=True` when loading the model, for example
|
21 |
+
|
22 |
+
```python
|
23 |
+
model = AutoModelForCausalLM.from_pretrained("NousResearch/Yarn-Mistral-7b-128k",
|
24 |
+
use_flash_attention_2=True,
|
25 |
+
torch_dtype=torch.bfloat16,
|
26 |
+
device_map="auto",
|
27 |
+
trust_remote_code=True)
|
28 |
+
```
