Meta has delayed the release of its larger generative AI model, Llama 4 Behemoth, from its original April launch to an unspecified date in the fall. The model’s multiple delays, reported by The Wall Street Journal, come as critics inside and outside of Meta question whether large generative AI models have reached a performance plateau.

The company’s struggle to improve the capabilities of latest AI model mirrors issues at some top AI companies.

This fresh delay adds to concerns that Meta could fall behind other major AI providers like OpenAI and Google.
