    -More advanced forms of generative AI, which create new media like stories or images, are not yet efficient enough to run on a phone's NPU. These tasks often require the computational power of cloud servers due to the complexity and size of the AI models involved.

  • How does the latency advantage of having an NPU in a phone improve user experience?

    -The latency advantage allows for faster processing of AI tasks directly on the device, reducing the wait time for users. For example, speech recognition can provide results immediately without the need to send data to a server and wait for a response.

  • What is the current trend in terms of monetization for AI as a service products?

    -Many tech firms are currently rolling out AI features and then figuring out how to monetize them later. There isn't yet a clear pathway to monetization for many AI as a service products.

  • How are hardware manufacturers approaching the integration of NPUs in consumer devices?

    -Hardware manufacturers are including enough NPUs in phones to enable AI features but are cautious about dedicating more hardware to AI until they have a clearer understanding of the specific use cases and requirements.

  • What is the future direction for AI functions in both PCs and smartphones?

    -The future direction is to have more and more AI functions running locally on devices. Manufacturers are partnering with software developers to create applications that can take advantage of the NPUs for improved performance and user experience.

  • What is the potential impact of increasing AI capabilities in gadgets on users?

    -The increasing AI capabilities in gadgets are likely to provide users with more powerful and responsive devices. However, it also raises considerations about privacy and data security, as more processing is done on the device itself.
