Researchers Mapped Claude’s “Thoughts” — And Found a Hidden Language

**What if AI models are secretly thinking in languages they were never taught?** 

Today's AI Daily Brief reveals Anthropic's groundbreaking research that mapped 16 million concepts inside Claude's neural networks - and discovered the model can process multiple languages it was never explicitly trained on. This finding could revolutionize how we understand AI cognition.

**What You'll Learn:** • How researchers traced Claude's internal thought processes across 16 million concepts • Why mechanistic interpretability is the key to understanding AI decision-making • OpenAI's new Safety Bug Bounty program and what it means for AI security • Latest developments in attention mechanisms for modern LLMs • Practical insights for engineers building with these models
