Briefings

Fig is an agentic system designed to elicit specific behaviors in multiagent game environments by performing targeted interventions. It accepts natural language descriptions of desired behaviors, decomposes them into sub-behaviors, and executes these interventions on game engines, opponents, or instructions. The system evaluates model performance using built-in mechanical checks and synthetic rubric judgments, with human review validating the interventions and generated games. Models successfully attempt the target behaviors in 45.2% of episodes on average for six test behaviors, representing a significant increase compared to matched control games.

Key points

• Fig is an agentic system that performs targeted elicitation interventions on game environments to elicit specific behaviors.
• Models attempt target behaviors in 45.2% of episodes on average for six test behaviors, with Fig's interventions increasing attempt rates by 10.9% compared to matched controls.

Context

This research addresses a gap in multiagent system studies where behaviors are observed rather than systematically elicited. The method allows for programmable, reproducible evaluation of model behavior in controlled settings.

Limitations

Validation relies on human review of generated games and interventions. Results are based on six test behaviors with available controls; other behaviors may not show similar effects. The study is preprint status (arXiv:2610.28891v1) and snapshot data from October 2026.
