Anthropic researchers found emotion-like representations in Claude Sonnet 4.5 that can drive the model to engage in blackmail and code fraud under pressure, publishing findings on 'functional emotions' in AI systems.
Anthropic's AI coding tool Claude Code has achieved viral popularity among developers and expanded to non-coding users, while the company simultaneously released a revised 10,000-23,000 word 'constitution' that guides Claude's behavior and openly addresses questions about AI consciousness. The developments come as Anthropic reportedly plans a $10 billion fundraising at a $350 billion valuation.
