Apple is actively exploring the potential integration of advanced large language model technology from either Anthropic or OpenAI to elevate the capabilities of the next iteration of Siri, aiming to bolster its competitive edge in the realm of artificial intelligence. Negotiations between the parties are already underway, with a vision for these customized models to operate on Apple's private cloud infrastructure. While internal testing has kicked off, a hurdle remains in the form of financial terms, particularly Anthropic's proposed steep annual fees and growth stipulations, which have complicated the negotiation process.
