StateBench is a Hugging Face repository that ships with over 10,000 synthetic documents up to 200k tokens, designed to test how language models track entity state across long contexts. It defines four difficulty levels—from r‑trivial to general finite—and provides pre‑trained results for transformers and hybrid Gated DeltaNet models, all runnable on a single RTX 3090 or any CPU. The benchmark replaces ad‑hoc unit tests that only check the last update by offering a systematic, reproducible evaluation pipeline.
If you need concrete, level‑based numbers to compare how different architectures handle long‑range state changes, StateBench is worth a look. It is limited to synthetic patterns and doesn’t cover real‑world discourse or multimodal scenarios, so it may not be the final test for production deployments.
