TextWorld
https://github.com/microsoft/TextWorld
Microsoft Research's TextWorld — a sandbox for training and evaluating RL agents on text-based games. Procedurally generates interactive-fiction games of tunable difficulty (map size, quest length, ingredients) with full ground-truth knowledge graphs. Used as the basis for the FirstTextWorld and TextWorld Challenge competitions.

When to use
Optimised for: not applicable - eval dataset, not a system
Anti-fit: not applicable - eval dataset, not a system
Pros & cons
Pros
Procedural generation gives unlimited variants; ground-truth KGs enable rigorous memory-architecture evaluation; lightweight (text-only).
Cons
Pure text limits transfer to embodied agents; quest structures simpler than human-authored IF; less popular post-LLM-era (LLMs nearly solve handcrafted IF zero-shot).
Claims & capabilities
Microsoft Research; ICML 2018; ground-truth KG for every generated game enables ablation studies on memory architectures

- LoCoMo T3
Conversations spanning up to 35 sessions / 300 turns / ~9K tokens, built from LLM-agent personas grounded on temporal event graphs and verified by human annotators. Tests QA (single-hop, multi-hop, temporal, commonsense, adversarial), event-graph summarisation, multimodal dialogue.
- GAIA T3
Benchmark for general AI assistants made of real-world questions that require reasoning, multimodality, web browsing and tool use, with a public leaderboard on Hugging Face. Traction: ~917 likes on the Hugging Face dataset
- LongBench T3
Tsinghua THUDM. 21 datasets across 6 categories (single-doc QA, multi-doc QA, summarisation, few-shot ICL, synthetic, code completion) in English + Chinese. ~6.7K words English / 13.4K chars Chinese average. v2 at ACL 2025 with harder, longer instances.
- LongMemEval T3
5 core memory abilities — info extraction, multi-session reasoning, temporal reasoning, knowledge updates, abstention — via 500 curated questions in synthetic chat histories. Two scales: LongMemEval-S (115K tokens), LongMemEval-M (up to 1.5M).
- RULER T3
NVIDIA. Extends NIAH with multi-needle retrieval, multi-hop entity tracing, aggregation, QA — configurable for arbitrary length / difficulty. Evaluated 17 long-context models on 13 tasks.
- InfiniteBench (∞Bench) T3
Tsinghua / OpenBMB. First benchmark with average input >100K tokens. 12 tasks across English + Chinese: long novel QA, code debugging, math in long context, summarisation, retrieval. Realistic documents (novels, code) rather than synthetic filler.
