AgentMercury: Your Agent Can Synthesize Verifiable Environments for Business Scenarios at scale

Builds executable, multi-service business environments from scenarios rather than tasks, with deterministic verifiers; then trains agents and world authors on them.

What it is

Synthesizes executable business worlds from high-level scenarios, then uses them to train agents and learn environment authoring itself. Instead of building environments around benchmark tasks, it builds persistent, verifiable business worlds from scenarios; tasks emerge later from the world, and construction traces supervise world authoring.

Key results

  • Qwen3.5-4B: 12.3 -> 15.7 on EnterpriseOps-GYM after RL training
  • Qwen3.5-4B: 45.9 -> 56.0 on AIME26 after training on AgentMercury
  • World authoring success: 3.3% -> 83.3% on held-out scenarios after fine-tuning

Scenario-grounded, verifiable worlds can provide transferable learning signals beyond benchmark-specific environment design.
