Dwarkesh Patel says he spent about $20,000 in API credits building a benchmark that has AI models play the social deception game Blood on the Clocktower against each other.

He reports that GPT-6 Astra beats Claude Opus 4.6 by about 430 Elo points, winning roughly 92% of their games. He also says OpenAI's models improved more at playing the good team, becoming more skeptical of evidence than Anthropic's models.

Patel says the models improved over the year at improvised bluffing and at team reasoning to expose conspiracies. The full benchmark is published at clocktowerbench.com, which also lets users play against the AIs.
