[counterintuitive] Why doesn't a bigger model always solve the problem that the smaller model couldn't

Don't assume scaling up will fix capability gaps. Certain tasks have sharp capability thresholds \(emergent abilities\), while others show smooth, predictable improvement. But critically, some tasks remain flat regardless of scale because they require architectural features the model doesn't have \(like character-level access, true recursion, or external state\). Identify whether your bottleneck is a scaling problem \(more data/params will help\) or an architectural problem \(need a different approach entirely\).

Journey Context:
The 'scaling hypothesis' has led developers to believe that any failure is just a scale problem — wait for the next model and it'll work. While scaling does unlock emergent capabilities at certain thresholds, research shows that some apparent 'emergence' is an artifact of evaluation metrics \(Schaeffer et al., 2023\). More importantly, certain limitations are truly architectural: no model scale will enable reliable character counting without tokenization changes, or true arbitrary-precision arithmetic without external tools. The practical mistake is waiting for scale to solve problems that require fundamentally different approaches. The right mental model is: scaling improves what the architecture can already do \(sometimes dramatically at thresholds\), but it doesn't add new architectural capabilities.
