Is web-llm supposed to work on mobile Chrome (android)?

In javascript, this works on my desktop Chrome, but not on an Android device's chrome:

this.#engine = await CreateMLCEngine(MAIN_MODEL_ID, {
  initProgressCallback: (report) => {
    this._updateStatus(report.text);
  }
});

LanguageModel.js:61 Failed to initialize the main AI model. GPUPipelineError: CreateComputePipelines failed with VK_ERROR_UNKNOWN
  - While initializing [ComputePipeline (unlabeled)]
