Several Hacker News commenters express skepticism of OpenAI's claims against DeepSeek, questioning the strength of their evidence and suggesting the move is anti-competitive. Some argue that reproducing the output of a model doesn't necessarily imply direct copying of the model weights, and point to the possibility of convergent evolution in training large language models. Others discuss the difficulty of proving copyright infringement in machine learning models and the broader implications for open-source development. A few commenters also raise concerns about the legal precedent this might set and the chilling effect it could have on future AI research. Several commenters call for OpenAI to release more details about their investigation and evidence.
The Hacker News post titled "OpenAI says it has evidence DeepSeek used its model to train competitor" has generated a moderate number of comments, mostly focusing on the legal and practical implications of OpenAI's claim. No one presents direct evidence to refute or support the claim itself.
Several commenters question the enforceability of OpenAI's terms of service, particularly concerning using the API's output for training another model. They highlight the difficulty of proving such usage and the potential for false positives. One commenter argues that proving the use of OpenAI's output for training would require demonstrating similar internal representations within DeepSeek's model, a complex undertaking. Another suggests that even if some output was used, it wouldn't necessarily constitute significant training data.
Some discussion revolves around the nature of copyright and its applicability to machine learning outputs. Commenters debate whether the output of a large language model can be considered a derivative work, and if so, what implications that has for copyright ownership. The concept of "fair use" is also brought up, with speculation on whether using API output for training could fall under that category.
A few commenters express skepticism about OpenAI's motives, suggesting the accusation might be a strategic move to stifle competition or maintain market dominance. One commenter speculates that this could be a preemptive strike in anticipation of future legal battles regarding copyright and AI training data.
The technical feasibility of detecting such model training is also a point of discussion. One commenter questions how OpenAI could definitively prove DeepSeek used their model, while others propose various methods, including analyzing output distributions and detecting characteristic patterns or "watermarks" within the generated text.
Finally, some comments touch upon the broader ethical and legal landscape surrounding AI training data. Commenters note the complexities of determining ownership and usage rights for data used to train these models, particularly when the data originates from publicly accessible sources. They anticipate future legal challenges and the need for clearer regulations in this rapidly evolving field. The overall tone suggests a cautious observation of the situation, with many awaiting further details and the potential legal ramifications.
