Summary

MerchantBench is a benchmark that assesses AI agents by having them manage a simulated online store for a year, revealing challenges with sustained performance and continuous action.

Most agent benchmarks end after one task, but running a store doesn't, and that's where these agents come apart. MerchantBench hands an agent a small online store and lets it run for a simulated year, sourcing products, setting prices, managing cash. It also scores something most evals skip: whether the agent is still acting at all. The best agent finished a simulated year of shopkeeping with about a quarter of what humans earned, mostly by going quiet, so track how often yours still acts. So log your agent's actions per window and watch that curve. A decent final score can hide an agent that stopped working months ago. – arxiv. org/abs/2607.28956 Title: "MerchantBench: Benchmarking LLM Agents for Long-Term Coherence in E-Commerce Operations"

StoreBench introduces a live-commerce RL environment where autonomous agents run an online apparel store with 29 merchant tools, testing long-horizon planning under uncertainty. No frontier LLM matches a scripted smart-triage baseline (best, DeepSeek-V4-Pro, passes 49% vs 97%), while GRPO post-training on Qwen3.5-27B substantially improves held-out performance.
