Anthropic gets heat for being the only major AI lab not supporting open models

Anthropic is the only major AI lab not supporting open-weight AI as companies like OpenAI, Google, Microsoft, and SpaceX signed a letter advocating for open models. The tech industry is criticizing Anthropic for its silence, with figures like David Sacks and Bill Gurley suggesting the company prioritizes economic strategy over open-source principles. Anthropic favors gated access to its models through initiatives like Project Glasswing.
