Duke study says better memory, not a bigger model, lifted ARC-AGI-3 scores by 18 points

Duke researchers found that memory, not a bigger model, may be the real bottleneck.
They logged every interaction, then let models search those logs with code. On ARC-AGI-3’s 25 public games, this approach improved performance by 18 percentage points over the same base agents.
The takeaway is simple: better external memory can matter more than scaling the core model.
