- •Anyone focused on embeddings workflows
Best for: Codestral Mamba
Mistral AI's 7B Mamba-architecture coding model released July 2024. Unlike transformer-based models, Codestral Mamba uses a state space model (SSM) backbone for linear-time inference — meaning latency doesn't grow with context length. Tested up to 256k tokens in-context. Performs on par with SOTA transformer models on code benchmarks at release. Open weights on Hugging Face under Apache 2.0. Available on La Plateforme as codestral-mamba-2407. Co-designed with Mamba authors Albert Gu and Tri Dao.
Ideal use cases:
- •Teams or individuals who need mamba (ssm) architecture: linear-time inference — response latency stays flat as context length grows
- •Teams or individuals who need 256k-token in-context retrieval tested — handles full codebases in a single context window
- •Teams or individuals who need 7,285,403,648 parameters — instructed model optimized for code generation and reasoning
