The Post-Transformer Era: Are State Space Models Like Mamba Really the Future?
The Post-Transformer Era: Are State Space Models Like Mamba Really the Future? TL;DR The machine learning community is buzzing about State Space Models (SSMs) and Mamba as potential successors to the dominant Transformer architecture. While the Reddit discussion generated significant engagement (82 upvotes, 28 comments), this research topic remains largely in academic and experimental phases. Mistral AI’s Codestral Mamba—an SSM-based code generation model—has already been deprecated since June 2025, raising questions about whether SSMs are truly ready to replace attention mechanisms or if they’re just another promising research direction that hasn’t quite delivered on its hype. ...
