Solaris, Carolina Principles, and Apple's AI handoff: 5 AI moves in 24 hours

In brief

Five developments

1. John Ternus takes over as Apple's CEO

• John Ternus became Apple's chief executive officer on September 1, succeeding Tim Cook, who moved to executive chairman; Arthur Levinson became lead independent director. 1
• Ternus joined Apple's product-design team in 2001, became a hardware-engineering vice president in 2013, and has led the hardware organization since 2021. 1
• Apple's succession announcement gives Ternus a hardware-led profile and no new AI product timetable, leaving AI execution and software coordination as the first questions for his tenure. 1

2. The U.S. takes a light-touch AI position to the G20

• U.S. tech adviser Michael Kratsios is set to press G20 members to avoid new AI rules and new AI regulatory bodies, according to prepared remarks reported by Reuters. 2
• The proposed Carolina Principles would reserve new regulation for novel concerns while encouraging foundational research and commercial opportunities; the meeting began in North Carolina on September 1. 2
• Sam Altman, Jensen Huang, Demis Hassabis, Elon Musk, and other technology leaders are scheduled to address the meeting, turning the position into a direct test of whether other governments accept the U.S. framework. 2

3. Runway previews an operating layer that generates interfaces

• Runway introduced Solaris, its first "Interface World Model," which generates an interactive interface frame by frame as a user clicks, drags, or types. 3
• Runway says Solaris targets real-time interaction, session-long coherence, and visual quality at 720p; the company is taking early-access requests while it works with partners toward a public launch. 3
• In Runway's study of 250 participants across 30 interaction examples, Solaris was preferred over a coded Claude Opus 5 result in 61% versus 24% of instruction-following comparisons and 71% versus 21% of natural-behavior comparisons. 3

4. OpenAI says ChatGPT Ads reached a USD 1 billion run rate

• OpenAI said ChatGPT Ads reached a USD 1 billion annualized revenue run rate in fewer than 200 days, with tens of thousands of advertisers using the platform. 4
• The company said ads are available in more than 40 countries, with self-service buying expanding to India, Europe, the Middle East, and North Africa on August 31. 4
• OpenAI says ads are labeled and kept separate from answers, advertisers do not receive private conversations, and users can control personalization; the rollout makes advertising a larger part of ChatGPT's free-tier economics. 4

5. LightNav-0 joins perception and control in one navigation model

• A 20-author arXiv technical report introduced LightNav-0, a compact vision-language model that represents navigation goals with a shared token interface and converts them into embodiment-specific trajectories. 5
• The training corpus spans more than 2,000 scenes and 4,000 hours of embodied-navigation data; the authors report state-of-the-art monocular success rates across all 10 public navigation simulations. 5
• The report also claims zero-shot transfer across robot embodiments and real-world scenes, making embodiment transfer the result to test beyond the paper's simulation scores. 5

The read-through

Watch next

• Apple's first AI and software decisions under Ternus, alongside Cook's work with policymakers as executive chairman. 1
• Whether G20 participants endorse the Carolina Principles, and how the proposal interacts with existing national AI rules. 2
• Solaris's public-access date, latency, text reliability, and grounding controls for longer sessions. 3
• OpenAI's advertising controls, market rollout, and whether the stated run rate holds as self-service access expands. 4
• Reproducible LightNav-0 checkpoints, code, and real-world evaluation details beyond the technical report's claims. 5
