PACT tests negotiation under partial information: persuasion, commitment, deception, anchoring, threats, and adaptation across repeated rounds. info, game logs, charts: GPT-5.5, Opus 4.7, DeepSeek V4 Pro, Gemini 3.1 Pro, Kimi K2.6 are the top 5. Note that opponent mixes vary by model and charts like Average Profit by Round do not control for them. submitted by /u/zero0_one1 [link] [comments]
