Anthropic criticized for refusing open models — only major AI lab without them

Anthropic has come under fire for being the only major AI laboratory that refuses to release open models. While competitors such as Google DeepMind, Meta, and Mistral actively support and release open-weight or open-source models, Anthropic maintains a closed approach. Critics argue that this hinders transparency and collaborative progress in AI safety and development. The debate highlights the growing divide in the AI community over open versus closed models.
