Unverified50% confidenceFactExact time
The training data, architecture details and evaluation methods of closed-source models are usually not disclosed, which makes academic research difficult to reproduce and verify, and also makes bias and safety issues difficult to audit externally.

UnverifiedPrivately held benchmark test data is not publicly available, meaning models cannot have seen the evaluation set during training, which more accurately reflects generalization ability and avoids leaderboard contamination.79% similarUnverifiedTraditional general-purpose models perform limitedly on cybersecurity tasks because security-domain corpora account for a low share of their training data, and they lack targeted evaluation benchmarks (such as CTF and vulnerability reproduction datasets).78% similarUnverifiedThe popular 'uncensoring fine-tuning' in the community typically only removes safety restriction layers and has no effect on the implicit biases caused by training data.75% similarUnverifiedBecause the sources of training data for open-source models are often difficult to fully trace and clean up, if courts rule that all training on unauthorized copyrighted content constitutes infringement, they will face greater compliance difficulties than commercial giants.73% similarUnverifiedEvaluation benchmarks face data contamination issues, where training data may already include test questions causing inflated scores; in the GPT-4 technical report, OpenAI publicly discussed this issue for the first time.73% similar
