1. **[RULER: What's the Real Context Size of Your Long-Context Language Models?](https://md.research.elamur.ai/free/en/papers/hsieh-2024-ruler-s-real-context-size/)** *(2024 · 386 citations)* Long-context language models are usually checked with the needle-in-a-haystack (NIAH) test. That test only shows whether a model can find one planted fact, so it says little about deeper use of long inputs. The NVIDIA authors built RULER, a fully synthetic benchmark whose input length and difficulty can be set…
2. **[Do Long-Range Language Models Actually Use Long-Range Context?](https://md.research.elamur.ai/free/en/papers/sun-2021-do-long-range-language-models/)** *(2021 · 100 citations)* Long-range Transformer language models can now read thousands of tokens of preceding text, and they reach lower perplexity on benchmarks such as PG-19.
