# Model Card for Mistral-7B-Instruct-v0.1
|
|
|
|
The Mistral-7B-Instruct-v0.1 Large Language Model (LLM) is a instruct fine-tuned version of the [Mistral-7B-v0.1](https://huggingface.co/mistralai/Mistral-7B-v0.1) generative text model using a variety of publicly available conversation datasets.
|
|
|
|
For full details of this model please read our [paper](https://arxiv.org/abs/2310.06825) and [release blog post](https://mistral.ai/news/announcing-mistral-7b/).
|
|
|
|
## Instruction format
|
|
|
|
In order to leverage instruction fine-tuning, your prompt should be surrounded by `[INST]` and `[/INST]` tokens. The very first instruction should begin with a begin of sentence id. The next instructions should not. The assistant generation will be ended by the end-of-sentence token id.
|
|
|
|
E.g.
|
|
```
|
|
text = "<s>[INST] What is your favourite condiment? [/INST]"
|
|
"Well, I'm quite partial to a good squeeze of fresh lemon juice. It adds just the right amount of zesty flavour to whatever I'm cooking up in the kitchen!</s> "
|
|
"[INST] Do you have mayonnaise recipes? [/INST]"
|
|
```
|
|
|
|
This format is available as a [chat template](https://huggingface.co/docs/transformers/main/chat_templating) via the `apply_chat_template()` method:
|
|
|
|
```python
|
|
from transformers import AutoModelForCausalLM, AutoTokenizer
|
|
|
|
device = "cuda" # the device to load the model onto
|
|
|
|
model = AutoModelForCausalLM.from_pretrained("mistralai/Mistral-7B-Instruct-v0.1")
|
|
tokenizer = AutoTokenizer.from_pretrained("mistralai/Mistral-7B-Instruct-v0.1")
|
|
|
|
messages = [
|
|
{"role": "user", "content": "What is your favourite condiment?"},
|
|
{"role": "assistant", "content": "Well, I'm quite partial to a good squeeze of fresh lemon juice. It adds just the right amount of zesty flavour to whatever I'm cooking up in the kitchen!"},
|
|
{"role": "user", "content": "Do you have mayonnaise recipes?"}
|
|
]
|
|
|
|
encodeds = tokenizer.apply_chat_template(messages, return_tensors="pt")
|
|
|
|
model_inputs = encodeds.to(device)
|
|
model.to(device)
|
|
|
|
generated_ids = model.generate(model_inputs, max_new_tokens=1000, do_sample=True)
|
|
decoded = tokenizer.batch_decode(generated_ids)
|
|
print(decoded[0])
|
|
```
|
|
|
|
## Model Architecture
|
|
This instruction model is based on Mistral-7B-v0.1, a transformer model with the following architecture choices:
|
|
- Grouped-Query Attention
|
|
- Sliding-Window Attention
|
|
- Byte-fallback BPE tokenizer
|
|
|
|
## Troubleshooting
|
|
- If you see the following error:
|
|
```
|
|
Traceback (most recent call last):
|
|
File "", line 1, in
|
|
File "/transformers/models/auto/auto_factory.py", line 482, in from_pretrained
|
|
config, kwargs = AutoConfig.from_pretrained(
|
|
File "/transformers/models/auto/configuration_auto.py", line 1022, in from_pretrained
|
|
config_class = CONFIG_MAPPING[config_dict["model_type"]]
|
|
File "/transformers/models/auto/configuration_auto.py", line 723, in getitem
|
|
raise KeyError(key)
|
|
KeyError: 'mistral'
|
|
```
|
|
|
|
Installing transformers from source should solve the issue
|
|
pip install git+https://github.com/huggingface/transformers
|
|
|
|
This should not be required after transformers-v4.33.4.
|
|
|
|
## Limitations
|
|
|
|
The Mistral 7B Instruct model is a quick demonstration that the base model can be easily fine-tuned to achieve compelling performance.
|
|
It does not have any moderation mechanisms. We're looking forward to engaging with the community on ways to
|
|
make the model finely respect guardrails, allowing for deployment in environments requiring moderated outputs.
