Meta, however, could push back the release of Llama 4 again, the report said, citing two people familiar with the matter. Big technology firms have been investing aggressively in AI infrastructure following the success of OpenAI’s ChatGPT, which altered the tech landscape and drove investment into machine learning. The report said one of the reasons for the delay is during development, Llama 4 did not meet Meta’s expectations on technical benchmarks, particularly in reasoning and math tasks.
