A paper says only GPT-6-Astra, of 12 LLMs, uncovered altered physical laws in LongChang, at a 16.7 percent rate.

LongChang is an automated framework that builds simulated worlds whose physics differ from ordinary laws and lets models explore without being told what to investigate. Separate agents generate scenes, review tools, and score reports from the altered laws and exploration records, without human intervention. Among 12 evaluated LLMs, the authors report that only GPT-6-Astra reached a 16.7 percent discovery rate; the other 11 scored 0 percent. Records showed uninvestigated anomalies and only partial identification of the changed laws.

Key facts
  • LongChang lets models explore worlds with altered physical laws without hints.
  • Scene generation, tool review, and scoring run without human intervention.
  • Only GPT-6-Astra, of 12 LLMs, recorded a 16.7 percent discovery rate.
  • The other 11 evaluated models scored a 0 percent discovery rate.
  • Records showed uninvestigated anomalies and only partial law identification.
