Tekkenizer

Tekkenizer

The new Tekkenizer class is based on Open AI's tiktoken and supports the new Mistral-Nemo model.

Tekkenizer always makes use of version 3 or higher.

Examples:

from mistral_common.tokens.tokenizers.mistral import MistralTokenizer

tokenizer = MistralTokenizer.v3(is_tekken=True)
tokenizer = MistralTokenizer.from_model("...")

Function calling (just like before)

# Import needed packages:
from mistral_common.protocol.instruct.messages import (
    UserMessage,
)
from mistral_common.protocol.instruct.request import ChatCompletionRequest
from mistral_common.protocol.instruct.tool_calls import (
    Function,
    Tool,
)
from mistral_common.tokens.tokenizers.mistral import MistralTokenizer

# Load Mistral tokenizer

model_name = "..."

tokenizer = MistralTokenizer.from_model(model_name)

# Tokenize a list of messages
tokenized = tokenizer.encode_chat_completion(
    ChatCompletionRequest(
        tools=[
            Tool(
                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"],
                    },
                )
            )
        ],
        messages=[
            UserMessage(content="What's the weather like today in Paris"),
        ],
        model=model_name,
    )
)
tokens, text = tokenized.tokens, tokenized.text

# Count the number of tokens
print(len(tokens))
