summary: Chrome’s on-device AI API received November 2024 updates that rename the package from the assistant-oriented label to a language model label, reducing confusion with Google Assistant. The API also now accepts inputs exceeding 1,024 tokens. The revised example reflects the new naming while retaining capability checks, model session setup, streamed responses, and unavailable-browser handling.

## Updated sample code

```javascript
async askAi(prompt) {
        const {available, defaultTopK } = await ai.languageModel.capabilities();

        if (available !== "no") {
            const systemPrompt = "You are a helpful assistant.";
            const session = await ai.languageModel.create({
                systemPrompt: systemPrompt,
                temperature: 0,
                topK: defaultTopK
            });

            const stream = session.promptStreaming(prompt);
            for await (const chunk of stream) {
                this.outputTarget.textContent = chunk;
            }
            session.destroy();
        } else {
            this.outputTarget.textContent = "Error! On-device AI is not available on your browser."
        }
}
```
