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

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 is reportedly pushing back the launch of its “Behemoth” AI model amid concerns about whether enough improvements have been made compared to previous iterations.
