May 20 (Reuters) - Apple ( AAPL ) is preparing to allow third-party developers to write

software using its artificial intelligence models, in a push to boost the creation of new

applications, Bloomberg News reported on Tuesday, citing people with knowledge of the matter.

The tech major is working on a software development kit and related frameworks that would

allow outsiders to build AI features based on the large language models that the iPhone maker

uses for Apple Intelligence, the report said.

Apple Intelligence - the company's own set of AI features, including capabilities such as

rewriting emails, summarizing notifications and editing photos - was rolled out last year.

The company expects to unveil the plan at its Worldwide Developers Conference on June 9,

Bloomberg said. Apple ( AAPL ) did not immediately respond to a Reuters request for comment.

Opening up its AI models would let developers integrate the underlying AI technology into

specific features or across their full apps, Bloomberg reported.

Apple ( AAPL ) will begin with opening up its smaller models that run on its devices, rather than the

more advanced cloud-based AI models that require servers, the report added.

The move could help Apple ( AAPL ), viewed by some analysts as a laggard in AI, compete against

rivals, such as Samsung Electronics ( SSNLF ), that have spruced up their devices with

features powered by the likes of Google.

It could also boost the appeal of Apple Intelligence among developers and users, after a

roll-out marked by delays.

Developers have so far been able to integrate Apple's ( AAPL ) AI tech into their applications, but

have not been able to use Apple's ( AAPL ) AI models to develop and power their own AI features.
