Gemma 3 27B runs on a MacBook Pro M4 or mid-range gaming PC. It matches GPT-4o-mini quality on most tasks — for free, offline, with complete privacy. No API costs, no data sent to servers, no usage limits.
Google released Gemma 3 in March 2026, continuing its commitment to powerful open-weights AI models. Unlike closed models from OpenAI and Anthropic, Gemma 3 can be downloaded and run entirely on your own hardware — your conversations never leave your device. For developers, researchers, businesses handling sensitive data, and privacy-conscious individuals, this is transformative.
