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. GPT-6 Astra used about 284 input and 93 output tokens per founder on gpt-6-astra, measured from the API usage fields. Cost is tokens times the provider's list price on 2026-09-24 ($10 input and $50 output per million tokens), so it recomputes when prices change. Build costs such as question or policy generation are excluded.
