For text classification, traditional TF-IDF + logistic regression works well for low-resource scenarios, BART-based models offer better accuracy but require training, while scikit-LLM with Groq-hosted LLM enables high-precision zero-shot classification with minimal code changes for production deployment.

入选理由:TF-IDF + 逻辑回归在小数据集上准确率约78%,推理速度快,适合资源受限场景。
