Our latest article explores how Mistral Codestral Mamba outperform even the most prominent models like Llama 7B. From exceptional benchmarks to model deployment, we’ve got all covered. Let’s get started!

What is Mistral Codestral Mamba?

Mistral Codestral Mamba is Mistral AI's latest model for code generation and language models. Named as a tribute to Cleopatra, it is a Mamba2 language model specialised in code generation. Codestral Mamba is built on the Mamba architecture, which offers several key advantages over conventional Transformer models.

Architecture Comparison of Mamba AI Model: Mamba2 vs. Transformer

Mamba2 and Transformer models represent two distinct approaches to sequence modelling in deep learning. While Transformers have become the standard for many large language models (LLMs), Mamba2 introduces a novel architecture based on state space models (SSMs) that addresses some of the limitations inherent in Transformer models.

Codestral Mamba AI Model has been specifically trained to excel in code generation and reasoning tasks. With 7,285,403,648 parameters, it's a substantial model that has been fine-tuned to understand and generate code across various programming languages. The model's design philosophy focuses on being a powerful local code assistant. It can handle in-context retrieval for sequences up to 256K tokens making it capable of understanding and working with extensive code contexts. 

Performance Benchmarks of Mistral Codestral Mamba

To understand the capabilities of Mistral Codestral Mamba 7B, it's essential to examine its performance across various benchmarks.

Benchmark Observations of Mistral Codestral Mamba

We have observed several key insights on the benchmarks of Codestral Mamba 7B: 

• Despite being a 7B parameter model, Codestral Mamba often outperforms or matches larger models, including some 22B and 34B variants.
• The model depicts exceptional performance across various programming languages and tasks, from basic coding problems to more complex database queries.
• The high scores achieved with fewer parameters highlight the effectiveness of the Mamba architecture in code-related tasks.
• While excelling in certain areas, Codestral Mamba maintains a balanced performance profile across different benchmarks, suggesting its utility as a general-purpose code assistant.
• Given that this is likely an early version of the model, there's potential for even better performance with further refinements and training.

How to Deploy Mistral Codestral Mamba?

Deploying Codestral Mamba 7B is designed to be flexible, catering to various use cases and infrastructure setups. The Mistral code AI model has provided several options for integrating the Codestral Mamaba model into your development environment:

Mistral Inference SDK

You can deploy Codestral Mamba 7B through the mistral-inference SDK. This software development kit is optimised to work with Mamba models and leverages the reference implementation from the official Mamba GitHub repository. 

TensorRT-LLM

If you want to deploy on NVIDIA GPUs with maximum performance, Codestral Mamba 7B is compatible with TensorRT-LLM. This toolkit optimises the model for inference on NVIDIA hardware that offers significant speed improvements.

Local Inference

While not immediately available, support for Codestral Mamba in llama.cpp is anticipated. This will allow for efficient local inference, particularly useful for developers who need to run the model on their machines or in environments with limited cloud access.

Raw Weights

For researchers and developers who want to implement custom deployment solutions, the raw weights of Codestral Mamba 7B are available for download from HuggingFace. 

La Plateforme

Mistral code AI has made Codestral Mamba 7B available on their “Le Plateforme” under the identifier codestral-mamba-2407 for easy testing. This allows you to quickly try the model without setting up your infrastructure.

Things to Consider for Mistral Codestral Mamba Deployment

While the latest Mistral code model shows exceptional performance, it's crucial to consider some important points to maximise its potential. 

• • Hardware Requirements: While Mamba models are generally more efficient than Transformers, Codestral Mamba still requires significant computational resources. You can start with NVIDIA RTX A6000 but we recommend NVIDIA L40, NVIDIA A100 for inference and NVIDIA H100 PCIe and NVIDIA H100 SXM for finetuning. Check out NVIDIA H100 80GB SXM5 performance benchmarks on Hyperstack to make an informed decision.
  • Batching: You may implement efficient batching strategies to maximise throughput, especially when dealing with multiple simultaneous requests.
  • Fine-tuning: You must consider fine-tuning the model on your specific codebase or domain for even better performance.
  • Monitoring: Set up proper monitoring and logging to track the model's performance and usage in your environment.

Case of Open Source for Mistral Codestral Mamba 

The decision of Mistral Codestral Mamba to release under the Apache 2.0 license is a huge win for the open-source community. The Apache 2.0 license offers several key benefits:

• Freedom to Use and Modify: Developers and researchers can freely use, modify and distribute Codestral Mamba without restrictive conditions. This approach encourages experimentation and adaptation of the model for various use cases.
• Patent Protection: The license includes a patent grant that provides users with protection against patent claims from contributors to the software. This is crucial in AI where patent concerns can sometimes hinder open collaboration.
• Commercial Use: Codestral 22B is available under a commercial license for self-deployment. This means businesses can integrate Codestral Mamba into their products or services without fear of licensing conflicts.
