HyperWrite, a New York startup, recently announced its AI model, Reflection 70B, as the new leader in open-source large language models (LLMs), only to face immediate scrutiny. Reflection 70B, based on Meta’s Llama 3 or possibly Llama 3.1, was claimed to have superior performance benchmarks. However, independent evaluators like Artificial Analysis have challenged these claims, unable to replicate the touted results. HyperWrite CEO Matt Shumer attributed discrepancies to issues during the model’s upload to Hugging Face, a third-party AI code repository. Despite Shumer’s explanations and a private API showing “impressive performance,” the AI community remains skeptical, with some accusing HyperWrite of fraud and others defending the model’s capabilities. This controversy highlights the volatile nature of AI development and the importance of transparent, verifiable results in the field. The AI research community eagerly awaits further clarification and the release of updated model weights for independent verification.
