Meta released Llama 4 in April. Llama -- Large Language Model Meta AI -- is Meta's family of LLMs. But Meta AI engineers are concerned the capabilities in the Behemoth LLM aren't a significant enough improvement over what's already available via Llama 4 to warrant a release next month, according to WSJ citing unnamed sources within Meta.

Meta Platforms is delaying the release of its flagship "Behemoth" AI model due to concerns about its capabilities, the Wall Street Journal reported on Thursday, citing people familiar with the matter.
