Covers Qwen3's model family (dense and MoE variants from 0.6B to 235B parameters), its 3-stage training pipeline on 36 trillion tokens, and benchmark performance. The implementation uses Hugging Face Transformers pipelines for both Qwen3-4B-Instruct and Qwen3-4B-Thinking models, with a Gradio web interface that lets users switch between modes and view collapsible reasoning traces. Part 1 of a 4-part series that will later add vision, safety, and RAG capabilities. ## Full article daily.dev links to this article rather than hosting it.
