Closed-source models typically possess a large number of capabilities not disclosed to the public (such as internal tool calls and private knowledge base retrieval) that cannot be reflected in standard benchmarks, causing public score comparisons to overestimate the degree to which open-source models are catching up.

UnverifiedThe capabilities of open-source models typically lag behind the latest commercial closed-source models.77% similarUnverifiedIf synthetic data originates from proprietary models or open-source models, there is generally no legal risk, but large-scale collection of outputs from a competitor's closed-source models may violate terms of service or even constitute unfair competition.72% similarUnverified通过LoRA等参数高效微调方法，恶意行为体仅需少量计算资源和数据即可移除开源模型内置的安全对齐，使得在模型层面防止滥用对开源生态几乎完全失效72% similarUnverifiedModel fine-tuning is a value unique to local deployment; fine-tuning open-source models on private datasets cannot be achieved through standard API calls.69% similarUnverifiedThe review pointed out that most models fail when externally validated, primarily due to domain shift and the absence of MLOps practices.67% similar
