output:
text: "Arr matey, a llama on yer lawn be a curious sight! Arr. First, ye might try to scare him off with a loud noise, like a cannon blast, Arr! If that don't work, ye could try to lure him away with some tasty treats, like carrots or apples, Arr. But beware, arr, if the llama be stubborn, ye might have to call in the help of a local animal control, or just live with him till he moves on, Arr!"
text: "[INST] What is your favourite condiment? [/INST]"
output:
text: "I don't have a personal preference or the ability to taste or enjoy condiments, as I'm an artificial intelligence and don't have a physical body or senses. However, I can tell you that some common favourite condiments include ketchup, mustard, mayonnaise, hot sauce, soy sauce, and BBQ sauce. People's preferences can vary greatly depending on their cultural background, dietary restrictions, and personal taste preferences."
Model Card for Mistral-7B-Instruct-v0.2
The Mistral-7B-Instruct-v0.2 Large Language Model (LLM) is an improved instruct fine-tuned version of Mistral-7B-Instruct-v0.1.
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 via the apply_chat_template() method:

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'
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.
