Good results fine tuning a local LLM like Qwen 3:0.6B to categorize questions

What happened

The teachmecoolstuff.com blog posted a hands-on guide showing that a fine-tuned local 0.6-billion-parameter Qwen 3 model delivers strong results on question categorization.

Context and impact

The post lands inside an intensifying debate over whether frontier models are overkill for most production deployments. For cost-sensitive teams with sensitive data it is a concrete playbook for moving off Claude/GPT to a self-hosted small model without losing quality on a narrow task.
