⚙️ Configuration

Tabby server will look for a configuration file at ~/.tabby/config.toml for advanced features.

Repository context for code completion

To enable repository level context for code completion, you can add the following to your configuration file:

# Index two repositories' source code as additional context for code completion.

[[repositories]]
git_url = "https://github.com/TabbyML/tabby.git"

[[repositories]]
git_url = "git@github.com:OpenNMT/CTranslate2.git"

Once this is set, you can run tabby scheduler to index the source code repository.

:::tip By default, tabby scheduler runs in a daemon and processes its pipeline every 5 hours. To run the pipeline immediately, use tabby scheduler --now. :::

~/.tabby % ls dataset
data.jsonl

In a code completion request, additional context from the source code repository will be attached to the prompt for better completion quality. For example:

// Path: crates/tabby/src/serve/engine.rs
// fn create_llama_engine(model_dir: &ModelDir) -> Box<dyn TextGeneration> {
//     let options = llama_cpp_bindings::LlamaEngineOptionsBuilder::default()
//         .model_path(model_dir.ggml_q8_0_file())
//         .tokenizer_path(model_dir.tokenizer_file())
//         .build()
//         .unwrap();
//
//     Box::new(llama_cpp_bindings::LlamaEngine::create(options))
// }
//
// Path: crates/tabby/src/serve/engine.rs
// create_local_engine(args, &model_dir, &metadata)
//
// Path: crates/tabby/src/serve/health.rs
// args.device.to_string()
//
// Path: crates/tabby/src/serve/mod.rs
// download_model(&args.model, &args.device)
    } else {
        create_llama_engine(model_dir)
    }
}

fn create_ctranslate2_engine(
    args: &crate::serve::ServeArgs,
    model_dir: &ModelDir,
    metadata: &Metadata,
) -> Box<dyn TextGeneration> {
    let device = format!("{}", args.device);
    let options = CTranslate2EngineOptionsBuilder::default()
        .model_path(model_dir.ctranslate2_dir())
        .tokenizer_path(model_dir.tokenizer_file())
        .device(device)
        .model_type(metadata.auto_model.clone())
        .device_indices(args.device_indices.clone())
        .build()
        .⮹

Usage Collection

Tabby collects usage stats by default. This data will only be used by the Tabby team to improve its services.

What data is collected?

We collect non-sensitive data that helps us understand how Tabby is used. For now we collects serve command you used to start the server. As of the date 10/07/2023, the following information has been collected:

struct HealthState {
    model: String,
    chat_model: Option<String>,
    device: String,
    arch: String,
    cpu_info: String,
    cpu_count: usize,
    cuda_devices: Vec<String>,
    version: Version,
}

For an up-to-date list of the fields we have collected, please refer to health.rs.

How to disable it

To disable usage collection, set the TABBY_DISABLE_USAGE_COLLECTION environment variable by export TABBY_DISABLE_USAGE_COLLECTION=1.
