Coding
Mistral Large, the top performer in coding tasks, is the premier choice for users who prioritize superior coding capabilities in their model selection. This advanced model consistently demonstrates exceptional proficiency in various coding applications, making it an invaluable tool for developers, programmers, and tech enthusiasts.
Here’s an example of this model writing a function to compute square roots using the Babylonian method. This demonstrates its advanced problem-solving and coding skills in a real-world application.
Prompt:
You are an expert Python programmer, and here is your task: Write a function for computing square roots using the babylonian method. Your code should pass these tests:
assert math.isclose(babylonian_squareroot(10),
3.162277660168379, rel_tol=0.001)
assert math.isclose(babylonian_squareroot(2),
1.414213562373095, rel_tol=0.001)
assert math.isclose(babylonian_squareroot(9),
3.0, rel_tol=0.001)
Output:
def babylonian_squareroot(number):
if(number == 0):
return 0;
g = number/2.0;
g2 = g + 1;
while(g != g2):
n = number/ g;
g2 = g;
g = (g + n)/2;
return g;"
Text Generation
The Mistral models enable interaction with a system that has been meticulously fine-tuned to follow instructions and respond to natural language prompts. A prompt, which serves as the input for the Mistral model, can take various forms such as a question, an instruction, or a few examples illustrating the desired task. Based on the provided prompt, the Mistral model generates a text output as a response.
The chat completion API processes a list of chat messages as input and produces a response in the form of a new chat message, with the role of “assistant.”
Chat messages
System Messages: These optional messages set the behavior and context for an AI assistant, such as modifying its personality or providing specific instructions. They can include task instructions, personality traits, contextual information, creativity constraints, and other guidelines to help the AI understand and respond to user inputs. For detailed setup, see the API reference.
User Messages: These messages are sent from the human’s perspective during a conversation with an AI assistant. They typically contain a request, question, or comment that the AI should respond to, allowing the human to initiate and guide the interaction.
Assistant Messages: Sent by the AI assistant back to the user, these messages usually respond to previous user prompts by following the given instructions. They can also appear at the beginning of a conversation to greet the user.
Tool Messages: These messages appear in the context of function calling. They are used at the final response formulation step when the AI needs to format the tool call’s output for the user. For more information, refer to the function calling guide.
Large Reasoning Capabilities
Mistral Large stands out as the optimal choice for handling complex tasks that demand extensive reasoning capabilities or high specialization. This includes applications such as Synthetic Text Generation, Code Generation, Retrieval-Augmented Generation (RAG), or intelligent agents.
Mistral Large outshines our other four models in commonsense and reasoning benchmarks, making it the premier option for tasks requiring sophisticated reasoning.

Mistral models power a wide range of large language model (LLM) applications at scale. Here’s a brief overview of the types of use cases and their corresponding Mistral models:
Simple Tasks: Ideal for bulk operations like classification, customer support, or text generation. These tasks are powered by Mistral Nemo.
Intermediate Tasks: Suitable for tasks requiring moderate reasoning such as data extraction, summarizing documents, writing emails, job descriptions, or product descriptions. These tasks leverage the capabilities of Mistral Small.
Complex Tasks: Designed for tasks that require extensive reasoning capabilities or are highly specialized, including synthetic text generation, code generation, RAG (retrieval-augmented generation), or creating agents. These tasks are powered by Mistral Large.
Upgrading to Recent Mistral Models
For those considering an upgrade, Mistral’s legacy models can be replaced by more recent, high-quality models. Here are some general comments to assist in the decision-making process:
Mistral Nemo outperforms Mistral 7B and is more cost-effective.
Mistral Small outperforms Mixtral 8x7B and offers better cost efficiency.
Mistral Large surpasses Mixtral 8x22B in performance while maintaining the same price ratio.
By understanding these distinctions and selecting the right model for your specific use case, you can optimize both performance and cost efficiency for your AI applications.
For those new to Large Language Models (LLMs), it is generally advisable to begin with Mistral Large. This model allows users to evaluate both its cost and performance, making it easier to decide whether a downgrade to Mistral Small or Mistral Nemo is necessary. For individuals already utilizing another large language model and seeking to replace a particularly powerful one, Mistral Large often emerges as the optimal choice.
