Apple is expected to unveil new artificial intelligence features at its annual Worldwide Developers Conference beginning Monday, marking the final such event under CEO Tim Cook's leadership before he hands over the role to John Ternus in September.

The developers conference, held at Apple's Silicon Valley headquarters and attracting thousands of developers from approximately 60 countries, typically focuses on software announcements rather than hardware launches. Analysts anticipate Apple will provide updates on AI capabilities, including significant developments to its Siri voice assistant.

Industry observers expect Siri to be reimagined as a more conversational AI chatbot with enhanced memory capabilities to recall previous conversations and the ability to handle multiple tasks from single requests. The upgraded assistant could potentially manage conversations and tasks across Apple's ecosystem of iPhones, Macs, and iPads.

Apple has been working to catch up with competitors in artificial intelligence development. The company currently uses Google's Gemini AI model to help power its AI features, as it seeks to deliver on AI promises made nearly two years ago.

Cook announced his retirement in April, concluding a 15-year tenure that saw Apple's market value increase by more than $4 trillion during the iPhone era. Ternus, who has been with Apple for 25 years and spent the past five overseeing engineering for the iPhone, iPad and Mac, will assume the CEO role.

The leadership transition occurs during a period of significant industry upheaval driven by artificial intelligence developments, representing the most substantial technological shift since the original iPhone launch in 2007.
