YouTube age verification, cancer drugs & more (August 12, 2025)

Good morning!

AI is waking up as it is predicting your reactions to movies before you press play, guessing your age before you start a Youtube video, and more. Plus, new AI startups emerge with momentum.

Let’s dive👇

🧠 Big AI Breakthroughs

🌌 Nvidia’s “Cosmos” World Models for Physical AI

Nvidia just dropped its new Cosmos suite, AI models that can understand, simulate, and control real-world physics for robotics, autonomous machines, and industrial automation. Paired with updated infrastructure, this is a push to make AI think in the physical domain, not just the digital one.

📊 Datumo Takes on Scale AI in LLM Evaluation

Seoul-based Datumo raised $15.5M to expand its LLM benchmarking platform, which grades models on everything from reasoning to cultural nuance. By targeting transparent, standardized AI evaluation, Datumo is challenging industry giants like Scale AI in the AI testing arms race.

💻 ChatGPT-5 Free in Cursor…Until Tomorrow, August 13th

Developers using Cursor, the AI-powered coding environment, can leverage free credits to test out ChatGPT-5. Normally a premium-tier feature, GPT-5 is temporarily unlocked for all users, letting them try its advanced reasoning, refactoring, and code-completion capabilities. Users are reporting wild discoveries.

🎯 AI in the Wild

🎥 YouTube’s AI Is Guessing Your Age

YouTube is testing AI that estimates viewer age using only their face in videos. It’s aimed at protecting minors from mature content but raises obvious privacy alarms, especially if it’s deployed beyond content moderation.

🏅 OpenAI’s Reasoner Wins at Programming Olympiad

OpenAI’s reasoning model placed 6th overall and 1st among AIs at the International Olympiad in Informatics, scoring in the 98th percentile without being fine-tuned for coding. That’s double last year’s performance and another sign human competition dominance is fading.

🧪 Korean AI Designs Cancer Drugs from Scratch

KAIST’s new diffusion model BInD designs precise cancer drug candidates without prior molecular data. It optimizes safety, stability, and manufacturability in a single step, potentially accelerating the arrival of AI-created precision medicine.

🛠 Tools of the Day

• Hera – Generate animated CTAs, charts, and ads from text prompts in seconds
• Kombai – AI agent for rapid frontend development
• Airbook AI – Cursor for analytics, aggregate all your data in one place

💡 Prompt of the Day

⚡ Quick Hits

• GitHub CEO resigns to launch a startup, GitHub moves under Microsoft CoreAI

• Meta builds a model that predicts how your brain will respond to a movie

• Alibaba’s Qwen3 LLM hits 1M token context length

• Anthropic adds chat memory to Claude for Max, Team, and Enterprise tiers

📌 TLDR

Nvidia’s Cosmos models bring AI to physical control, Datumo challenges Scale AI on model evaluations, YouTube tests age-guessing AI, OpenAI dominates a coding Olympiad, and KAIST designs cancer drugs without prior data.

See you tomorrow,
