Model Card for Mixtral-8x22B-Instruct-v0.1

The Mixtral-8x22B-Instruct-v0.1 Large Language Model (LLM) is an instruct fine-tuned version of the Mixtral-8x22B-v0.1.

Run the model

encodeds = tokenizer_v3.encode_chat_completion(mistral_query).tokens
model = AutoModelForCausalLM.from_pretrained("mistralai/Mixtral-8x22B-Instruct-v0.1")
model_inputs = encodeds.to(device)
model.to(device)

generated_ids = model.generate(model_inputs, max_new_tokens=1000, do_sample=True)
sp_tokenizer = tokenizer_v3.instruct_tokenizer.tokenizer

print(decoded)

Alternatively, you can run this example with the Hugging Face tokenizer. To use this example, you'll need transformers version 4.39.0 or higher.

pip install transformers==4.39.0

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "mistralai/Mixtral-8x22B-Instruct-v0.1"
tokenizer = AutoTokenizer.from_pretrained(model_id)
conversation=[
    {"role": "user", "content": "What's the weather like in Paris?"},
    {
        "role": "tool_calls",
        "content": [
            {
                "name": "get_current_weather",
                "arguments": {"location": "Paris, France", "format": "celsius"},
                
            }
        ]
    },
    {
        "role": "tool_results",
        "content": {"content": 22}
    },
    {"role": "assistant", "content": "The current temperature in Paris, France is 22 degrees Celsius."},
    {"role": "user", "content": "What about San Francisco?"}
]


tools = [{"type": "function", "function": {"name":"get_current_weather", "description": "Get▁the▁current▁weather", "parameters": {"type": "object", "properties": {"location": {"type": "string", "description": "The city and state, e.g. San Francisco, CA"}, "format": {"type": "string", "enum": ["celsius", "fahrenheit"], "description": "The temperature unit to use. Infer this from the users location."}},"required":["location","format"]}}}]

# render the tool use prompt as a string:
tool_use_prompt = tokenizer.apply_chat_template(
            conversation,
            chat_template="tool_use",
            tools=tools,
            tokenize=False,
            add_generation_prompt=True,

)
model = AutoModelForCausalLM.from_pretrained("mistralai/Mixtral-8x22B-Instruct-v0.1")

inputs = tokenizer(tool_use_prompt, return_tensors="pt")

outputs = model.generate(**inputs, max_new_tokens=20)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Instruct tokenizer

The HuggingFace tokenizer included in this release should match our own. To compare: pip install mistral-common

from mistral_common.protocol.instruct.messages import (
    AssistantMessage,
    UserMessage,
)
from mistral_common.tokens.tokenizers.mistral import MistralTokenizer
from mistral_common.tokens.instruct.normalize import ChatCompletionRequest

from transformers import AutoTokenizer

tokenizer_v3 = MistralTokenizer.v3()

mistral_query = ChatCompletionRequest(
    messages=[
        UserMessage(content="How many experts ?"),
        AssistantMessage(content="8"),
        UserMessage(content="How big ?"),
        AssistantMessage(content="22B"),
        UserMessage(content="Noice 🎉 !"),
    ],
    model="test",
)
hf_messages = mistral_query.model_dump()['messages']

tokenized_mistral = tokenizer_v3.encode_chat_completion(mistral_query).tokens

tokenizer_hf = AutoTokenizer.from_pretrained('mistralai/Mixtral-8x22B-Instruct-v0.1')
tokenized_hf = tokenizer_hf.apply_chat_template(hf_messages, tokenize=True)

assert tokenized_hf == tokenized_mistral

Function calling and special tokens

This tokenizer includes more special tokens, related to function calling :

• [TOOL_CALLS]
• [AVAILABLE_TOOLS]
• [/AVAILABLE_TOOLS]
• [TOOL_RESULTS]
• [/TOOL_RESULTS]

If you want to use this model with function calling, please be sure to apply it similarly to what is done in our SentencePieceTokenizerV3.
