A few months after its initial release, the Chrome on-device AI has some breaking changes on the API.
1) Package
# Previous
window.ai
# New
ai.assistant
2) Checking availability of the API.
const {available, defaultTopK } = await ai.assistant.capabilities();
if (available !== "no") {
// available
}
3) New create API
const session = await ai.assistant.create({
temperature: 0,
topK: defaultTopK
});
4) Sending System Prompt is now possible.
const systemPrompt = "You are a helpful assistant.";
const session = await ai.assistant.create({
temperature: 0,
topK: defaultTopK,
systemPrompt: systemPrompt
});
The streaming API and streaming output remain unchanged.
