Google Releases Gemma 4 Open Models Built to Run Fully On-Device Without Cloud or API Keys

Google DeepMind has released Gemma 4, a family of open-weight generative AI models that includes edge-optimized variants capable of running entirely on a phone or laptop with no internet connection, no API keys, and no server costs after download. The launch, made available under the permissive Apache 2.0 license, pushes lightweight local AI beyond simple chatbots into agentic territory, adding multi-step planning, tool calling, and multimodal processing that all execute on the user's own hardware.
