Pinned Qwen3 1.7B Q8_0 GGUF: artifact metadata, SHA256 verification, and streaming downloader.

Example

import { ensurePinnedModel, getPinnedModel } from '@exodus/qwen3-model-js'

const { filename } = getPinnedModel()
await ensurePinnedModel(`./models/${filename}`, {
  onProgress: ({ fraction }) => console.log(`${(fraction * 100).toFixed(1)}%`),
})

Exports

• getPinnedModel() — returns the frozen artifact record (repo, filename, sha256, sizeBytes, downloadUrl, license).
• verifyPinnedModelFile(path) — streams the file and throws on size or SHA256 mismatch.
• ensurePinnedModel(path, opts?) — verifies if present, otherwise downloads to a temp file, verifies, and atomically renames into place. Returns { downloaded }. Opts: onProgress, signal, timeoutMs (default 30 min, 0 disables).
• ModelMissingError — thrown when the file isn't on disk.
• ModelHashMismatchError — thrown on size or SHA256 mismatch; carries path, expected, actual.
