Run open-weight AI on your own machine.

Brazier is a free, open-source desktop client and local API for running open weight AI models. Chat with LLMs, run computer use to operate your browser and desktop, run sandboxed agents, generate images and video, and build with a local OpenAI-compatible API — no cloud, no telemetry, all on your hardware.

Everything in one desktop app

Chat & LLMs

Run local language models with llama.cpp, MLX-LM, and MLX-VLM backends. Persistent branching conversations, search, attachments, cancellation, and import/export.

Agents

A broker-sandboxed agent core with its own tools, policy approvals, and OS sandboxing (Seatbelt on macOS, Bubblewrap on Linux). Pi provides the orchestration loop; optional Oh My Pi adds a fuller coding harness.

Image & video

Generate media with stable-diffusion.cpp, and let LLMs call media generation as tools in multi-round conversations.

Day-one model support

Build engine forks straight from a repository URL — llama.cpp, MLX, whisper.cpp, stable-diffusion.cpp, and PersonaPlex. When a new model lands in an upstream fork, you don't have to wait for a Brazier release.

Local API

An OpenAI-compatible API with Models, Chat Completions, and Responses, plus transcription, generation, and agent endpoints.

Your hardware, your data

Managed runtimes, system runtime discovery, and activation. Hardware-sized model recommendations and Hugging Face search. No telemetry, ever.
