🏷️ gliclass-rs: GLiClass inferences in Rust

💬 Introduction

gliclass-rs is an inference engine for GLiClass language models.

These models are efficient for zero-shot topic classification or derivatives like sentiment analysis. They can also be used for efficient re-ranking.

"GLiClass" stands for "Generalist and Lightweight Model for Sequence Classification", after an original work from Knowledgator, which was itself inspired by GLiNER.

gliclass-rs is built in pure Rust, as an 🧩 orp pipeline.

🎓 Examples

[dependencies]
"gliclass-rs" = "0.9.x"

use gliclass::{GLiClass, params::Parameters, input::text::TextInput};

let gliclass = GLiClass::new("tokenizer.json", "model.onnx", Parameters::default())?;
        
let input = TextInput::from_str(
    &[
        "Rust is a systems programming language focused on safety, speed, and concurrency.",
        "Traveling is the perfect way to explore new cultures through their food.",
        "Traveling for science allows researchers to collaborate with experts worldwide.",
    ],
    &["computing", "science", "programming", "travel", "food", "politics"]
);    

let classes = gliclass.inference(input)?;

for i in 0..classes.len() {
    println!("Text {i}: {}", classes.best_label(i, None).unwrap());        
}

Please refer the the source code in examples for complete examples.

🧬 Models

Currently gliclass-rs has been tested with the following models:

It should work out-of-the-box with other equivalent models, please report your own experiments.

⚠️ Take care of setting the prompt_first parameter according the selected model's expectations (the appropriate value is indicated in the config.json that goes with the model).
