GPT-5 on VCBench
GPT-5 scores F0.5 16.2 on VCBench, the venture capital benchmark from the University of Oxford and Vela Research, with 59.1% precision and 4.2% recall on the 4,500-founder private test set. That is rank 27 of 32, 1.5× the F0.5 of tier-1 VCs and 1.9× Y Combinator, at $11.23 per 1,000 founders scored.

Compared with the reference rows
| Entry | Precision | Recall | F0.5 | Cost / 1k |
|---|---|---|---|---|
| GPT-5 | 59.1% | 4.2% | 16.2 | $11.23 |
| 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. GPT-5 used about 284 input and 1,087 output tokens per founder on gpt-5, estimated from the prompt and the saved responses; reasoning models are assumed to think about 1,000 tokens per founder. Cost is tokens times the provider's list price on 2026-09-24 ($1.25 input and $10 output per million tokens), so it recomputes when prices change. Build costs such as question or policy generation are excluded.
Frequently asked questions
- What does GPT-5 score on VCBench?
- GPT-5 scores F0.5 16.2 on VCBench, with 59.1% precision and 4.2% recall, rank 27 of 32 as of 2026-10-07.
- Does GPT-5 beat human investors at predicting founder success?
- Yes. Its F0.5 is 1.5 times that of tier-1 VCs (10.7) and 1.9 times Y Combinator (8.6), after both are normalized to the dataset's 9% base rate.
- How much does GPT-5 cost per 1,000 founders?
