AI models get convenient amnesia about source material as they grow, MIT boffins find - The Register

Larger LMs show declining source attribution fidelity as scale increases The effect was measured across model sizes using controlled probe tasks on synthetic and real-world data Findings suggest trade-offs between capability scaling and traceability of knowledge origins
Emphasizes novelty and implication while minimizing methodological constraints, lack of causal mechanism, and absence of real-world validation beyond synthetic probes.
Rigorous academic discovery uncovering an emergent, counterintuitive property of AI systems with governance relevance.
Larger AI models forget where their knowledge comes from — a phenomenon called 'convenient amnesia'.
No discussion of mitigation strategies or whether the effect is reversible via alignment techniques; No comparison to human memory decay or cognitive science analogues; No mention of dataset curation practices that may amplify or suppress the effect
Combines academic authority (MIT), accessible metaphor ('amnesia'), and implied urgency ('as they grow') to elevate a controlled experimental observation into a structural concern. The claim feels larger than warranted because it implies inevitability and consequence without demonstrating downstream impact — the tension lies between precise probe results and expansive governance framing.
Larger language models exhibit reduced ability to recall or attribute source material used during training.
The Register reports MIT researchers 'found' that 'AI models get convenient amnesia about source material as they grow' — citing experimental evaluation across model sizes.
