OpenAI has officially launched GPT-6 Astra, its first AI model classified at the "Critical" cybersecurity capability level under its Preparedness Framework, demonstrating 99.9% performance on ARC-AGI-3 and 100% on ExploitBench. Meanwhile, Google DeepMind unveiled WeatherNext 3, a next-generation meteorological model that ingests live geostationary satellite feeds to deliver global hourly forecasts at up to 5 km resolution.

We’ll talk about:

• OpenAI deploying GPT-6 Astra with strict isolation, checkpoint encryption, and continuous monitoring following "Critical" cyber capability benchmarks.
• A global weather AI model processing real-time satellite imagery to deliver 15-day ensemble predictions and hourly forecast refreshes.
• Nvidia securing control of the platform serving 18M+ open-source AI de ...
