The controversy surrounding the AI language model Reflection 70B continues to spark debate. Sahil Chaudhary, co-developer of the model, has now published a post-mortem report. In it, he admits mistakes in the rushed release and explains discrepancies between the originally claimed and actual performance data. According to Chaudhary, a programming error led to inflated results in some benchmarks. He also provided resources for the AI community to test the model themselves. Despite efforts to provide transparency, many experts remain skeptical and doubt the credibility of the explanations.
