Claude Plays Pokemon (Anthropic)
https://www.twitch.tv/claudeplayspokemon
Anthropic's public Twitch livestream of Claude (3.7 Sonnet → Claude 4 Opus) playing Pokemon Red. Agent uses screenshot vision + Game Boy controller actions + a scratchpad memory file the model can edit. Demonstrates long-horizon agentic capability publicly; ran continuously from Feb 2025; viewed by hundreds of thousands cumulatively; key data point for Anthropic's marketing around Claude as a long-horizon agent.

When to use
Optimised for: benchmarking long-horizon agentic capability via game play
Anti-fit: not applicable - eval dataset, not a system
Pros & cons
Pros
Public, observable, real-time evidence of long-horizon LLM-agent capability; high mindshare; live discussion of failure modes (loops, forgetting, hallucinating items).
Cons
Closed agent harness (Anthropic-internal); not reproducible by third parties; benchmark protocol informal — no standardized scoring.
Claims & capabilities
Anthropic-run Twitch stream Feb 2025 onwards; Claude 3.7 Sonnet reached Mt. Moon / 2 badges over ~80hr; later runs with Claude 4 Opus reached deeper progress; one of the most-watched public LLM-agent demos of 2025

- 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).
