Apple delivered its strongest June quarter on record, reporting $109.4 billion in revenue and beating analysts' estimates of $108.65 billion in its final earnings report before CEO Tim Cook steps down.

In an interview, Cook addressed Apple's approach to open-source artificial intelligence, U.S.-China relations, rising memory chip costs, and his legacy after 15 years at the helm. Cook said he has "nothing negative" to say about open-source AI models, adding "they are useful." His comments come amid a debate over whether powerful AI systems should remain proprietary or be broadly available. That debate intensified after Chinese AI company Moonshot launched Kimi K3, a model rivaling systems from Anthropic and OpenAI. Apple is preparing to launch its AI-powered Siri this fall using Google's Gemini.

I'm very optimistic at this point about where the relationship is." Apple Intelligence has been approved in China after a delay of nearly two years.
