Google Ships Stealth Gemma 4 Update (July 16)

No version bump, no blog post — just updated weights on Hugging Face with three real improvements:

What changed:

• Flash Attention 4 support — 25–70% prefill speedup on H100/H200 GPUs


• Tool calling bug fixes — multi-step function calling now works reliably (truncated JSON, incorrect function selection, dropped arguments — all fixed)


• Vision improvements — better multimodal understanding across all sizes (9B–34B)

Why you should care:
Gemma 4 is Apache 2.0 — fully open, no rate limits, no tracking.

1. FA4 makes real-time chat agents viable on single-GPU setups (prefill ~3s to under 1s for 8K context)
2. Fixed tool calling removes the #1 blocker for production agentic workflows on open-weight models
3. Silent update = your Docker images & CI/CD with baked-in old weights won't auto-update

Action: If you have Gemma 4 cached locally before July 16, re-pull:

huggingface-cli download google/gemma-4-34b-it --force-download
