A Chinese whistleblower from Meta’s AI team on Llama 4:

After repeated training, the performance of the internal model still fails to reach open-source SOTA levels, and is even far behind them. Company leadership suggested mixing various benchmark test sets into the post-training process, aiming to produce a result that “looks okay” across multiple metrics. If the set deadline at the end of April isn’t met, they may stop further investment.

After Llama 4 was released yesterday, there were already many poor real-world performance results shared on X (Twitter) and Reddit. As someone who’s currently also active in academia, I find this practice unacceptable.

Therefore, I’ve submitted my resignation request and have explicitly asked that my name not be included in Llama 4’s Technical Report. I’ve also heard that Meta’s VP of AI resigned for the same reason.
