(Reuters) -Apple ( AAPL ) is weighing using artificial intelligence technology from Anthropic or OpenAI to power a new version of Siri, instead of its own in-house models, Bloomberg News reported on Monday.

The iPhone maker has had discussions with both companies about using their large language models for Siri, asking them to train versions of their LLMs that could run on Apple's ( AAPL ) cloud infrastructure for testing, the report said, citing people familiar with the discussions.

Apple ( AAPL ) and OpenAI did not immediately respond to Reuters requests for comment. Anthropic declined to comment.

The company had in March said AI improvements to its voice assistant Siri will be delayed until 2026, without giving a reason for the setback.
