I grabbed gemma4.app on launch day and built this in 48 hours

Gemma 4 dropped on April 3rd. I noticed gemma4.app wasn't registered yet and grabbed it immediately. 48 hours later here's what's live: - Live playground using the 26B MoE via OpenRouter (no signup) - Mobile deployment guide — Android and iOS have different official paths and I couldn't find a clear comparison anywhere - Local setup for Ollama, llama.cpp, LM Studio, MLX - Hardware/VRAM planning guide - Troubleshooting for OOM and GGUF runtime issues Still building: local config generator (pick VRAM → get Ollama command), prompt comparison tool, app directory. Happy to answer questions about any of the deployment paths. What are you most interested in running Gemma 4 for? https://gemma4.app
