# Model Card |
|
|
|
The Model is an instruct fine-tuned version of the Mistral-7B-v0.2. |
|
|
|
Mistral-7B-v0.2 has the following changes compared to Mistral-7B-v0.1 |
|
- 32k context window (vs 8k context in v0.1) |
|
- Rope-theta = 1e6 |
|
- No Sliding-Window Attention |
|
|
|
|
|
## 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-v0.2") |
|
tokenizer = AutoTokenizer.from_pretrained("mistralai/Mistral-7B-Instruct-v0.2") |
|
|
|
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]) |
|
``` |
