Show HN: I benchmarked Gemma 4 E2B – the 2B model beat the 12B on multi-turn

After last month's Gemma 4 E4B benchmark, the obvious follow-up: can the 2B variant deliver real generational improvement at constant parameter count? It can. Multi-turn doubled. RAG grounding jumped 17 points. The E2B scored 80.4% overall — 0.4 points behind a model with twice its parameters.
