Ollama runs on Android just fine via Termux. I use it with 5GB models. They even recently added ollama package, there is no longer need to compile it from source code.

Ollama enables deploying LLMs models locally on laptops and edge severs, Cactus enables deploying on phones. Deploying directly on phones facilitates building AI apps and agents capable of phone use without breaking privacy, supports real-time inference with no latency, we have seen personalised RAG pipelines for users and more.
Apple and Google actively went into local AI models recently with the launch of Apple Foundation Frameworks and Google AI Edge respectively. However, both are platform-specific and only support specific models from the company. To this end, Cactus:
- Is available in Flutter, React-Native & Kotlin Multi-platform for cross-platform developers, since most apps are built with these today.
- Supports any GGUF model you can find on Huggingface; Qwen, Gemma, Llama, DeepSeek, Phi, Mistral, SmolLM, SmolVLM, InternVLM, Jan Nano etc.
- Accommodates from FP32 to as low as 2-bit quantized models, for better efficiency and less device strain.
- Have MCP tool-calls to make them performant, truly helpful (set reminder, gallery search, reply messages) and more.
- Fallback to big cloud models for complex, constrained or large-context tasks, ensuring robustness and high availability.
It's completely open source. Would love to have more people try it out and tell us how to make it great!
We are a dev toolkit to run LLMs cross-platform locally in any app you like.
