Each fashions can be found on varied platforms reminiscent of Hugging Face, Mistral AI’s platform, and main cloud service suppliers like Google Cloud Platform, Azure AI Studio, Amazon Bedrock, and IBM watsonx.ai (Mistral AI | Frontier AI in your arms).
The Agentic Paradigm and Operate Calling
Each Mistral Giant 2 and Mistral NeMo embrace an agentic-centric design, which represents a paradigm shift in how we work together with AI fashions. This method focuses on constructing fashions able to interacting with their setting, making selections, and taking actions to attain particular objectives.
A key characteristic enabling this paradigm is the native assist for perform calling. This permits the fashions to dynamically work together with exterior instruments and companies, successfully increasing their capabilities past easy textual content technology.
Let’s take a look at an instance of how perform calling would possibly work with Mistral Giant 2:
from mistral_common.protocol.instruct.tool_calls import Operate, Software from mistral_inference.transformer import Transformer from mistral_inference.generate import generate from mistral_common.tokens.tokenizers.mistral import MistralTokenizer from mistral_common.protocol.instruct.messages import UserMessage from mistral_common.protocol.instruct.request import ChatCompletionRequest # Initialize tokenizer and mannequin mistral_models_path = "path/to/mistral/models" # Guarantee this path is appropriate tokenizer = MistralTokenizer.from_file(f"{mistral_models_path}/tokenizer.model.v3") mannequin = Transformer.from_folder(mistral_models_path) # Outline a perform for getting climate info weather_function = Operate( title="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 user's location.", }, }, "required": ["location", "format"], }, ) # Create a chat completion request with the perform completion_request = ChatCompletionRequest( instruments=[Tool(function=weather_function)], messages=[ UserMessage(content="What's the weather like today in Paris?"), ], ) # Encode the request tokens = tokenizer.encode_chat_completion(completion_request).tokens # Generate a response out_tokens, _ = generate([tokens], mannequin, max_tokens=256, temperature=0.7, eos_id=tokenizer.instruct_tokenizer.tokenizer.eos_id) end result = tokenizer.decode(out_tokens[0]) print(end result)
On this instance, we outline a perform for getting climate info and embody it in our chat completion request. The mannequin can then use this perform to retrieve real-time climate knowledge, demonstrating the way it can work together with exterior programs to supply extra correct and up-to-date info.
Tekken: A Extra Environment friendly Tokenizer
Mistral NeMo introduces a brand new tokenizer known as Tekken, which is predicated on Tiktoken and skilled on over 100 languages. This new tokenizer affords vital enhancements in textual content compression effectivity in comparison with earlier tokenizers like SentencePiece.
Key options of Tekken embody:
