(EXPERIMENTAL) Defines an inference "backend" that uses Chrome's on-device model, and encapsulates logic for detecting when on-device inference is possible.
These methods should not be called directly by the user.
Signature:
export interface ChromeAdapter
Methods
ChromeAdapter.generateContent()
Generates content using on-device inference.
This is comparable to GenerativeModel.generateContent() for generating content using in-cloud inference.
Signature:
generateContent(request: GenerateContentRequest): Promise<Response>;
Parameters
Returns:
Promise<Response>
ChromeAdapter.generateContentStream()
Generates a content stream using on-device inference.
This is comparable to GenerativeModel.generateContentStream() for generating a content stream using in-cloud inference.
Signature:
generateContentStream(request: GenerateContentRequest): Promise<Response>;
Parameters
Returns:
Promise<Response>
ChromeAdapter.isAvailable()
Checks if the on-device model is capable of handling a given request.
Signature:
isAvailable(request: GenerateContentRequest): Promise<boolean>;
Parameters
Returns:
Promise<boolean>
