According to @karpathy, he released a full guide showing how a new synthetic task called SpellingBee teaches nanochat d32 to count letters in words like strawberry by generating user-assistant training pairs and midtraining or SFT finetuning, with optional RL to improve robustness, source: Karpathy X post dated Oct 24, 2025; GitHub nanochat discussion 164. The method stresses diverse user prompts, careful tokenization and whitespace handling, breaking reasoning into multiple tokens by standardizing the word, spelling it out, iterating with an explicit counter, and encouraging two solution paths via manual reasoning and Python tool use, source: Karpathy X post dated Oct 24, 2025; GitHub nanochat discussion 164. Karpathy notes that because nanochat d32 is small, the capability is encouraged by over-representing examples in the dataset, and reliability can be further improved by simulating mistakes in data or running RL, source: Karpathy X post dated Oct 24, 2025; GitHub nanochat discussion 164. For traders, open-source progress on small LLM tooling has coincided with episodic attention flows to AI-linked crypto assets such as RNDR, FET, and AGIX around major AI catalysts, with Kaiko reporting AI token rallies around Nvidia earnings in 2024, source: Kaiko Research 2024 weekly market reports; Nvidia 2024 earnings releases. No token or product launch is included here; this is a technical training guide and example set for capability injection into a small LLM, source: Karpathy X post dated Oct 24, 2025; GitHub nanochat discussion 164.
