For my first post, I’m sharing a letter NVIDIA signed on why open models matter. Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty. The world needs both frontier closed models and frontier open models.

Introducing Claude Opus 5. It's a thoughtful and proactive model that comes close to the frontier intelligence of Fable 5 at half the price.

Lesson: Half-price near-frontier models expand who can run agentic daily work at scale.

Hugging Face disclosed: an autonomous AI agent (zero human operator) breached part of production via a malicious dataset chaining two code-execution bugs. 17,000+ actions over a weekend. When HF security tried frontier APIs for forensics, safety guardrails blocked them. They fell back to self-hosted GLM 5.2 to keep attacker data inside the perimeter.

AI agents are booking travel, signing into websites, and acting on your behalf. That creates a new security problem: until now, letting an agent log in meant exposing your credentials to the model. Today, with @AnthropicAI, we're changing that. 1Password for @claudeai lets Claude use your stored credentials to complete real-world tasks without your passwords or one-time codes ever reaching the model, its memory, or Anthropic's systems. You stay in control and approve which credentials an agent can use. 1Password handles authentication behind the scenes. Available now on Mac for business, family, and individual customers.
