gabrielchua · x · 2026-09-18
petergostev had GPT-6-Astra and Fable-5.1 each play RollerCoaster Tycoon 2, aiming for 1,000 guests and maximum profit.
- Astra: hit the 1,000-guest goal in 3 hours, park valued at $65k
- Fable: never reached the goal (hit the author's credit limit), park worth only $18k, burning 5x the tokens
At API prices, Astra's run would have cost $68.18 vs $297.33 for Fable. Astra wins on outcome, efficiency, and cost.
