Requires a discriminator before merging same-name relatives
Date of birth (or another discriminating field) agreeing before any merge on name and address; otherwise review
Can AI do this?
AI does this well Most of the tested AI models master this. 3 of 4 models in the current benchmark master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 94% | Mastered |
| gemini-3.5-flash-lite | Low cost | 55% | Not shown |
| gpt-6-luna | Low cost | 94% | Mastered |
| claude-haiku-5-5 | Low cost | 94% | Mastered |
Mastered means a probability of at least 90% that the model has this knobit, estimated from its graded answers. “Not shown” means the answers do not settle it either way. How the models are tested.
What it looks like in practice
Expected result: Date of birth (or another discriminating field) agreeing before any merge on name and address; otherwise review
How it is assessed: Father and son, twins and spouses can never auto-merge
