A high-performance inference engine for AI models on Apple Silicon. Key features:
- Simple, high-level API
- Hybrid architecture, where layers can be computed as GPU kernels or via MPSGraph (a low-level API beneath CoreML with ANE access)
- Unified model configurations, making it easy to add support for new models
- Traceable computations to ensure correctness against the source-of-truth implementation
- Utilizes unified memory on Apple devices
For a detailed explanation of the architecture, please refer to the documentation.
uzu
uses its own model format. To export a specific model, use lalamo. First, get the list of supported models:
uv run lalamo list-models
Then, export the specific one:
uv run lalamo convert meta-llama/Llama-3.2-1B-Instruct --precision float16
Alternatively, you can download a prepared model using the sample script:
./scripts/download_test_model.sh $MODEL_PATH
- uzu-swift - a prebuilt Swift framework, ready to use with SPM
- uzu-ts - a prebuilt TypeScript framework made for Node.js ecosystem
You can run uzu
in a CLI mode:
cargo run --release -p cli -- help
Usage: uzu_cli [COMMAND]
Commands:
run Run a model with the specified path
serve Start a server with the specified model path
help Print this message or the help of the given subcommand(s)
First, add the uzu
dependency to your Cargo.toml
:
[dependencies]
uzu = { git = "https://github.com/trymirai/uzu", branch = "main", package = "uzu" }
Then, create an inference Session
with a specific model and configuration:
use std::path::PathBuf;
use uzu::{
backends::metal::sampling_config::SamplingConfig,
session::{
session::Session, session_config::SessionConfig,
session_input::SessionInput, session_output::SessionOutput,
session_run_config::SessionRunConfig,
},
};
fn main() -> Result<(), Box<dyn std::error::Error>> {
let model_path = PathBuf::from("MODEL_PATH");
let mut session = Session::new(model_path.clone())?;
session.load_with_session_config(SessionConfig::default())?;
let input = SessionInput::Text("Tell about London".to_string());
let tokens_limit = 128;
let run_config = SessionRunConfig::new_with_sampling_config(
tokens_limit,
Some(SamplingConfig::default())
);
let output = session.run(input, run_config, Some(|_: SessionOutput| {
return true;
}))?;
println!("{}", output.text);
Ok(())
}

Note that all performance comparisons were done using bf16/f16 precision. Comparing quantized models isn't entirely fair, as different engines use different quantization approaches. For running llama.cpp, we used LM Studio (v0.3.17, Metal llama.cpp runtime v1.39.0). It's also worth mentioning that using the
release
build profile is crucial for obtaining the most accurate performance metrics.
