GPT 5.5 Tops Private Citation Benchmark on Kaggle — AbstractToTitle Task Recovers Exact Paper Titles

r/singularity·medium signal

GPT 5.5 achieved top performance on a private Kaggle citation benchmark (AbstractToTitle) that tests whether a model can recover the exact title of a published scientific paper given only its abstract — not generating plausible titles, but matching real ones. The r/singularity post hit 58 upvotes and 11 comments with benchmark screenshots. This task requires memorization of the training corpus at a granular level, suggesting GPT 5.5's knowledge base is significantly deeper than predecessors for academic content.
