The Built-in AI APIs are a set of browser APIs that implement a task driven APIs, including summarization which overlaps with the ones in the web-ai-toolkit.

While the goal would be that all browsers support the Built-in AI APIs, we know that it will take time until it's available across all browsers and platforms, so I was wondering if you've considered using the Built-in APIs for task where the API exists (Summarization), then relying on downloading a model when it doesn't.
