UnverifiedChoosing a model at the 4B parameter level (such as Qwen3.5-4B) is a pragmatic engineering choice: neuron-by-neuron visualization and editing on larger models is unrealistic in compute and memory, while smaller models have semantic behavior that is not rich enough.79% similarUnverifiedThe choice of a 4B-scale base model is intended to strike a balance between accommodating complex classification logic and controlling the computational overhead of fine-tuning inference.75% similarUnverifiedOn-device small models still have a clear gap with cloud-based large models on complex reasoning tasks; Gemma 4 E2B is suitable for lightweight conversation and instruction following, but its capability boundary is obvious in multi-step logical reasoning or long-context understanding.75% similarUnverifiedThe effectiveness of chain-of-thought reasoning exhibits emergent behavior with model scale: it is nearly ineffective on smaller models and only significantly improves reasoning accuracy on sufficiently large models.71% similarUnverifiedAfter keyword hints were introduced, the 1B model went from always answering asking_questions to usually selecting the correct stage, while the 4B model sometimes disagreed with the hints, which the author believes indicates the model is making its own judgment.70% similar
