Report #103332

[counterintuitive] A bigger model will eventually stop making tokenization-induced character errors.

Treat exact character/string tasks as requiring tool use or a character-aware architecture; do not rely on scale or prompt engineering.

Journey Context:
Scaling enthusiasts assume parameter count overcomes all micro-errors. StringLLM experiments and BPE analyses show that because subword tokenizers merge arbitrary character sequences, the model's input never exposes character boundaries or lengths. Fine-tuning can improve specific tasks but does not give the architecture native character access; the only robust fixes are explicit character-level tooling or tokenization redesign. Scale improves pattern completion within token units, not across them.
