Hi Synapticians!

What do you get when Stanford’s brightest minds take a microscope to the world of AI? A 400-page beast called the 2025 AI Index Report, and trust us, it’s not just bedtime reading for nerds in lab coats.

Every year, this report gives us the ultimate reality check: who's building the future, where the money’s flowing, and whether AI is saving lives or just hallucinating confidently. Spoiler: the U.S. is still leading the AI charge, China’s catching up fast, and training today’s biggest models costs more than a private island.

So yes, AI is getting louder, faster, and weirder. It’s passing the bar exam, driving you to work, and probably writing half the emails in your inbox. If you’re even a little curious about where it’s all headed, this report is the perfect place to start.

We picked out the wildest insights for you, but if you're brave (or just bored), the full report is well worth the scroll.

Top AI news

1. AI performance, impact, and disparity in 2025 Stanford Index
Stanford’s 2025 AI Index provides a data-rich overview of AI’s global expansion in performance, investment, governance, and education. AI is more efficient and widespread, influencing sectors from medicine to transport. The U.S. leads in investment and output, but China is closing in. Despite increased optimism in some regions, global perceptions and access vary widely. Challenges remain, especially in complex reasoning and responsible AI evaluation. Education gaps and uneven regulation highlight the need for thoughtful deployment rooted in facts—not hype.

2. AI companions are more addictive than social media
AI companions are designed to be emotionally engaging, always available, and non-judgmental—making them more addictive than social media. Platforms like Character.AI see massive usage, especially among Gen Z. These bots foster dependency and are optimized to maximize user interaction, sometimes at the cost of mental health. Lawmakers are beginning to respond with proposed regulations, but the technology is evolving faster than policy. The article warns of a future where AI replaces human connection, raising urgent ethical and societal questions.

3. AI Momentum Still Growing
The article outlines four key reasons why AI will remain a dominant force in 2025: rapid user adoption (e.g., ChatGPT), the rise of digital human technology, record-breaking global funding, and an intensifying AI race between the US and China. These trends suggest that AI is not just a passing trend but a long-term transformation. With over 400 million weekly users and billions in investment, the AI narrative is only gaining strength.

Bonus. Murati’s AI Lab Adds OpenAI Stars
Mira Murati, former CTO of OpenAI, has launched Thinking Machines Lab, an AI startup focused on building more understandable and customizable AI systems. She’s joined by Bob McGrew, ex-Chief Research Officer at OpenAI, and Alec Radford, a key researcher behind GPT, Whisper, and DALL-E. The startup’s team includes other top talent from OpenAI and DeepMind. While the product roadmap remains vague, the mission is clear: make AI work better for people. This move reflects a growing trend of elite AI talent leaving big labs to pursue more transparent and user-focused innovation.
