The Story
On April 2, 2026, Google released Gemma 4. Its gemma4 architecture wasn't supported by any training framework.
On April 9, we shipped the first working fine-tune. Seven days. We built custom Gemma 4 support into our training framework and shipped before anyone else.
Unsloth published their Gemma 4 training guide on July 18 — three months later.
140,000+ people downloaded v1. Zero community issues. v2 is our thank you — 10x the training data.
