October 7, 2021, while wondering whether [AK](https://hf.co/akhaliq) was a bot or a human, I saw one of his [tweets](https://twitter.com/_akhaliq/status/1445931206030282756).

Intrigued by the results announced, I decided to read about this S3 model, which would be renamed less than a month later to [S4](https://twitter.com/_albertgu/status/1456031299194470407) ([link](https://github.com/lbourdois/blog/blob/master/assets/efficiently_modeling_long_sequences_s3.pdf) of the version from when it was still called S3 for those interested).  
This brilliant article impressed me. At the time, I was convinced that State Space Models (SSM) were going to be a revolution, replacing transformers in the coming months. Two years later, I'm forced to admit that I was completely wrong, given the tsunami of LLMs making the news in NLP.  
Nevertheless, on Monday December 4, 2023, the announcement of Mamba by [Albert Gu](https://twitter.com/_albertgu/status/1731727672286294400) and [Tri Dao](https://twitter.com/tri_dao/status/1731728602230890895) revived their interest. This phenomenon was accentuated 4 days later with the announcement of [StripedHyena](https://twitter.com/togethercompute/status/1733213267185762411) by Together AI.  
A good opportunity for me to write a few words about the developments in SSM over the last two years.

I plan to write three articles first, where the aim is to illustrate the basics of SSM with S4 before doing a literature review of the evolution of SSM since that first paper:  
- [Introduction to SSM and S4](https://huggingface.co/blog/lbourdois/get-on-the-ssm-train)
- [SSM's history in 2022](https://huggingface.co/blog/lbourdois/ssm-2022)
- [SSM's history in 2023](WIP) (WIP)
