Overview

MistralAI Model Profiles is an auto-generated data module that defines capability profiles (token limits, modality support, tool calling) for Mistral AI models.

Description

The _profiles.py file in the langchain-mistralai partner package contains a dictionary named _PROFILES that maps Mistral AI model identifiers to their capability metadata. Each profile entry includes maximum input/output token counts, supported input/output modalities (text, image, audio, video), reasoning output capability, and tool calling support. This data is auto-generated by the langchain-profiles CLI tool from the models.dev project and should not be manually edited. The profiles are consumed by ChatMistralAI to automatically set model profile metadata for token counting and capability detection.

Usage

This module is used internally by ChatMistralAI during initialization to populate the model's profile with appropriate token limits and capabilities. It is not typically imported directly by end users.

Usage Examples

Accessing a Model Profile

from langchain_mistralai.data._profiles import _PROFILES

profile = _PROFILES.get("mistral-large-latest")
print(profile["max_input_tokens"])   # 262144
print(profile["tool_calling"])       # True
print(profile["image_inputs"])       # True
