3. [LongBench](https://aibenchmarkindex.com/global/online/longbench.md), Memory, Online: Evaluates bilingual long-context understanding across single- and multi-document question answering, summarization, few-shot learning, and code.
4. [LongBench v2](https://aibenchmarkindex.com/global/online/longbench-v2.md), Memory, Online: Tests deep reasoning over realistic contexts from 8,000 to two million words using difficult multiple-choice questions.
