Google releases FunctionGemma, a specialized version of the Gemma 3 270M model tuned for function calling to run locally on edge devices. Fine-tuning on the Mobile Actions dataset boosts accuracy from a 58% baseline to 85%, enabling reliable execution on hardware like the NVIDIA Jetson Nano. The model uses Gemma's 256k vocabulary to efficiently tokenize JSON inputs while routing complex tasks to larger models like Gemma 3 27B.written, reviewed, cited
- The model supports deployment using LiteRT-LM, vLLM, MLX, Llama.cpp, Ollama, Vertex AI or LM Studio.
- Developers can access the Mobile Actions guide with a Colab notebook and dataset to train their own specialized agent.
- The model runs 100% locally in a browser for physics simulation puzzles powered by FunctionGemma and Transformers.js.
