Researchers have developed a Graph Memory Transformer (GMT) that replaces the standard Feed-Forward Network (FFN) sublayer in decoder-only transformers with an explicit learned memory graph. This new architecture maintains causal self-attention but uses a memory cell to route token representations over a bank of centroids connected by a directed transition matrix. While the GMT model, with 82.2M parameters, trains stably and offers inspectable components, it currently underperforms a dense GPT-style baseline in validation loss and perplexity, though it shows comparable zero-shot benchmark behavior.
