The transformer architecture serves as the foundation for modern large language models, multimodal systems, and computer vision models, making its core mechanics and trade-offs essential knowledge for engineering teams.
The article highlights how earlier sequence modelling methods, like RNNs and LSTMs, struggled with gradient degradation and strictly sequential token processing that could not leverage GPU parallelism. While early seq2seq models introduced attention to solve fixed-vector representation bottlenecks, they still relied on recurrent steps. The transformer eliminated recurrent loops entirely in favour of parallel attention, unlocking modern large-scale pre-training at the cost of quadratic compute scaling over context length.

A research team led by Sepp Hochreiter introduces xLSTM, an extension of the original Long Short-Term Memory architecture designed for large-scale language modelling. The approach addresses historical scaling limits of LSTMs and demonstrates competitive performance against state-of-the-art Transformers and State Space Models.

Albert Gu and Tri Dao introduce Mamba, a sequence modeling architecture based on selective structured state space models (SSMs). It achieves linear scaling with sequence length, eliminates attention and MLP blocks, and delivers five times higher inference throughput than Transformers.

Byte-pair encoding (BPE), originally introduced in 1994 by Philip Gage for data compression, serves in a modified form as the foundation for modern large language model tokenizers. Rather than aiming for maximum compression, the LLM adaptation builds a fixed token vocabulary by iteratively merging frequent n-grams.

AI research company Subquadratic has introduced SubQ, a model designed for multi-million token reasoning. By using a proprietary algorithm called Subquadratic Sparse Attention (SSA), the company aims to significantly cut compute and memory demands compared to traditional Transformer-based architectures on large contexts.
