Researchers have developed a new framework called Temporal Critique Fine-Tuning (TCFT) to address a common failure in large language models (LLMs) where they exhibit temporal leakage, using knowledge that became available after a specified cutoff date. TCFT trains models to identify, explain, and judge the temporal admissibility of their responses. Experiments conducted on Qwen2.5-7B-Instruct and Qwen2.5-14B-Instruct models demonstrated that TCFT significantly reduces temporal leakage compared to standard prompting and supervised fine-tuning methods.
