Compared with the reference rows
| Entry | Precision | Recall | F0.5 | Cost / 1k |
|---|---|---|---|---|
| GPTree | 19.4% | 27.2% | 20.6 | $0.12 |
| Think-Reason-Learn Ensemble | 40.6% | 30.1% | 37.9 | $0.87 |
| Tier-1 VCs | 23.0% | 5.2% | 10.7 | n/a |
| Y Combinator | 14.0% | 6.9% | 8.6 | n/a |
| Random Classifier | 9.0% | 9.0% | 9.0 | $0 |
Human rows are normalized to the dataset's 9% success rate, so every entry is compared on the same base rate. Costs use list prices on 2026-09-24.
How it was scored
An LLM reads each founder profile at scoring time and returns a prediction. GPTree used about 2,930 input and 2,499 output tokens per founder on Typesafe System One (jev-1.13.0), measured from the API usage fields. Cost is tokens times the provider's list price on 2026-09-24 ($0.042 input and $0 output per million tokens), so it recomputes when prices change. Build costs such as question or policy generation are excluded.
