Ayush Pande writes that the Gemma 4 E2B model offers impressive performance for running local LLMs on Raspberry Pi hardware. While many small models fail at complex reasoning or produce hallucinations, this specific variant achieves a balance of capability and efficiency through its per-layer embedding design. This technique reduces effective computation to approximately 2.3 billion parameters despite having more total parameters, allowing it to run smoothly on modern single-board computers for tasks like summarization and image identification.
- E4B is smarter but runs at ~2.5–3 t/s
- Supports multimodal audio and visual inputs
- Raspberry Pi 5 achieves roughly 6 tokens per second
