Quick Start

Quick Start

Backyard AI is a platform to create, share, and engage with AI-powered Characters.

Our desktop application (opens in a new tab) is powered by large language models (LLMs) that run directly on your Mac/PC hardware. This local processing ensures complete privacy and prevents any form of 3rd party interference; no one can access your data, filter your conversations, or change the behavior of your AI. We also offer a zero-logging Cloud service (opens in a new tab) and secure mobile tethering (opens in a new tab) capabilities for those who want to access Backyard AI on-the-go.

You can build your own bespoke Character, or select one from our community-driven marketplace (opens in a new tab) for a diverse range of role-playing experiences.

Get the app


Backyard AI is available as a desktop application for MacOS Apple Silicon, MacOS Intel, and Windows. You can download the client at https://backyard.ai (opens in a new tab).

Select a model

Our team recommends the following models to start:

  • Kunoichi 7B: Good for lower-end devices, and excels at a wide range of tasks. This model is a great starting point for most users.
  • Mythomax-Kimiko 13B: A mid-sized, highly capable model. Recommended for users with at least 16gb of RAM.
  • Psyonic-Cetacean 20B: A larger model that is great for complex role-plays. This model is recommended for users with more powerful computers.

Note that both of these models, and most others available on Backyard AI, are unfiltered. Please use your discretion when evaluating text generated by these models.

Pick a character

For your first experience, we recommend downloading a Character from the Character Hub (opens in a new tab). You can access the Hub from within the app, or in the browser (opens in a new tab).
