Bonsai 27B running locally on iPhone: 27 billion parameter AI model
The AI model Bonsai 27B has been demonstrated running entirely locally on an iPhone, representing a significant breakthrough for executing large language models (LLMs) directly on consumer devices with limited hardware.
What happened?
A Reddit user has reported successfully running the AI model Bonsai 27B locally on an iPhone. The model, which features 27 billion parameters, was able to run directly on the device without the need for a cloud connection. The model occupies 3.9 GB of storage space on the phone, which is remarkable for a model of this size.

Why it matters
This development is significant as it enables advanced AI functions to be used offline, improving data protection and reducing dependence on network access and cloud services. The ability to run such large models on a mobile device like an iPhone indicates a trend towards more decentralised AI, where processing power is shifted from data centres to end-user devices.
Who is affected?
Developers working on the optimisation of AI models for mobile platforms are directly affected. Furthermore, smartphone end-users can expect to use more capable AI assistants and applications running directly on their devices in the future, resulting in improved performance and privacy.
What else you should know
Bonsai 27B uses advanced quantisation techniques to reduce the model's size from approximately 27 GB to 3.9 GB, which is crucial for it to run on limited hardware like a smartphone. This is an example of how technologies such as GGUF (GGML) and 4-bit quantisation are becoming vital for locally executed LLMs.
