According to Anthropic (@AnthropicAI), following the release of Claude Sonnet 4.5, the company has open-sourced a new automated audit tool designed to test AI models for behaviors such as sycophancy and deception. This move aims to improve transparency and safety in large language models by enabling broader community participation in alignment testing, which is crucial for enterprise adoption and regulatory compliance in the fast-evolving AI industry (source: AnthropicAI on Twitter, Oct 6, 2025). The open-source tool is expected to accelerate responsible AI development and foster trust among business users seeking reliable and ethical AI solutions.
