According to @karpathy, he resurfaced a paragraph from the 2021 GSM8K paper in a Sep 13, 2025 X post, highlighting ongoing attention to LLM reasoning evaluation (source: Andrej Karpathy, X post on Sep 13, 2025). GSM8K is a grade‑school math word‑problem benchmark designed to assess multi‑step reasoning in language models, making it a primary metric for tracking verified reasoning improvements (source: Cobbe et al., GSM8K paper, 2021). Because the post does not announce a new model, dataset, or benchmark score, there is no immediate, verifiable trading catalyst for AI‑linked crypto assets at this time (source: Andrej Karpathy, X post on Sep 13, 2025). Traders should wait for measurable GSM8K score gains or product release notes before positioning, as GSM8K is specifically used to quantify reasoning progress (source: Cobbe et al., GSM8K paper, 2021).
