FM Evaluation Pipeline

[biosynthart]

• CLIP (ViT-B/32) and DINOv2 for embedding rendered simulation frames
• Three ASAL search modes:
  • Supervised target — "find parameters matching these ecological prompts" (e.g., "thriving meadow" → "overgrazing" → "rain recovery")
  • Open-endedness — maximize trajectory novelty in FM embedding space over long rollouts
  • Illumination — discover maximally diverse set of ecosystem configurations
• CMA-ES optimization (gradient-free, handles 600-dim search spaces)
• Physical plausibility constraints (square-cube law, thermal homeostasis limits, trophic sanity)
