Run Gemma 4 Locally in 2026: 31B Dense Setup Guide with Ollama
Gemma 4 31B Dense runs locally on a single RTX 4090 or Mac M3 Max using Ollama — no API key, no data leaving your machine. Install Ollama, run ollama pull gemma4:31b, and you have a model that scores 87.1% on MMLU, beating GPT-4o’s 86.5%, running entirely on your hardware. What Is Gemma 4 31B Dense and Why Run It Locally? Gemma 4 31B Dense is a 31-billion-parameter language model released by Google DeepMind on April 2, 2026, under the Apache 2.0 license. Unlike mixture-of-experts architectures that distribute parameters across sparse expert layers, the 31B Dense model activates all 31 billion parameters on every token — giving it more reliable reasoning depth than larger MoE models with similar active parameter counts. In benchmark testing, Gemma 4 31B scores 87.1% on MMLU (beating GPT-4o’s 86.5%), 89.2% on AIME 2026, and 84.3% on GPQA Diamond — outperforming Llama 4 Scout’s 109B MoE model on the harder science benchmarks. Running it locally means zero API costs, complete data privacy, no rate limits, and the ability to integrate with any tool via the OpenAI-compatible REST endpoint that Ollama exposes on localhost:11434. For developers, researchers, or privacy-conscious users, this is the highest-performing open model available for on-device inference as of mid-2026. ...
