PANews reported on April 8 that at 1:49 am today, Ahmad Al-Dahle, the generative AI leader of Meta Platforms (META.O), published a long article on the social platform, officially responding to the doubts about Llama 4, which was just open-sourced the day before yesterday. Ahmad said that Llama 4 was released as soon as it was developed, so it is inevitable that there will be some differences in the quality of the models in different services. Meta will soon fix these vulnerabilities and improve performance. At the same time, he denied that pre-training was performed on the test set.
