Also covered by: @Santiago #7 ▶️ Google just casually disrupted the open-source AI narrative… Fireship Google’s Gemma 4 is a 31 billion-parameter, Apache 2.0-licensed open-source LLM that runs locally in 20 GB on an RTX 4090 by using TurboQuant and per-layer embeddings for compression. Gemma 4 big model (31 B parameters) downloads in 20 GB and delivers ~10 tokens/sec on a single RTX 4090, while its Edge variant can run on a phone or Raspberry Pi. TurboQuant compresses model weights by converting Cartesian data to polar coordinates and applying the Johnson–Lindenstrauss transform to quantize values to single sign bits while preserving distances. Models named E2B and E4B use “effective parameters” via per-layer embeddings, giving each transformer layer its own token embedding to introduce information exactly when needed.
