Function: resolveModelFile()

function resolveModelFile(uriOrPath: string, optionsOrDirectory?: 
  | string
  | ResolveModelFileOptions): Promise<string>

Defined in: utils/resolveModelFile.ts:153

Resolves a local model file path from a URI or file path, and downloads the necessary files first if needed.

If a URL or a URI is given, it'll be resolved to the corresponding file path. If the file path exists, it will be returned, otherwise it will be downloaded and then be returned.

If a file path is given, and the path exists, it will be returned, otherwise an error will be thrown.

Files are resolved from and downloaded to the directory option, which defaults to node-llama-cpp's default global models directory (~/.node-llama-cpp/models).

Set the cli option to false to hide the download progress from the console.

Parameters

Parameter	Type
uriOrPath	string
optionsOrDirectory?	| string | ResolveModelFileOptions

Returns

Promise<string>

The resolved model file path

Examples

import {fileURLToPath} from "url";
import path from "path";
import {getLlama, resolveModelFile} from "node-llama-cpp";

const __dirname = path.dirname(fileURLToPath(import.meta.url));

// resolve a model from Hugging Face to the models directory
const modelPath = await resolveModelFile(
    "hf:user/model/model-file.gguf",
    path.join(__dirname, "models")
);

const llama = await getLlama();
const model = await llama.loadModel({modelPath});

import {fileURLToPath} from "url";
import path from "path";
import {getLlama, resolveModelFile} from "node-llama-cpp";

const __dirname = path.dirname(fileURLToPath(import.meta.url));

// resolve a model from a URL to the models directory
const modelPath = await resolveModelFile(
    "https://example.com/model.gguf",
    path.join(__dirname, "models")
);

const llama = await getLlama();
const model = await llama.loadModel({modelPath});

import {fileURLToPath} from "url";
import path from "path";
import {getLlama, resolveModelFile} from "node-llama-cpp";

const __dirname = path.dirname(fileURLToPath(import.meta.url));

// resolve a local model that is in the models directory
const modelPath = await resolveModelFile(
    "model.gguf",
    path.join(__dirname, "models")
);

const llama = await getLlama();
const model = await llama.loadModel({modelPath});
