Researchers have introduced the Global State Model (GSM), a novel causal encoder-decoder architecture designed to enhance language model efficiency. GSM separates historical information acquisition from deep computation by using an encoder to aggregate long-range information into a shared state, which decoder layers then process without repeated historical access. This approach makes decoder attention and cache costs independent of history length, while dependency-aware pruning reduces prefill computation. Experiments indicate that GSM achieves performance comparable to DeepSeek-V4.1-Flash baselines, with potential improvements at certain scales, while also boosting training and inference throughput and lowering cache overhead.
