A modular two-agent simulation framework enables controlled comparison of conversational e-commerce responders, showing rolling-window memory outperforms intent extraction and targeted fixes reduce failures by 62%.
Introduces ShopTrajQA long-context benchmark and an RLVR-trained tool-augmented agent that bypasses LLM context limits by external file storage and code-based retrieval for shopping trajectories.
SimPersona induces a discrete buyer-type space from clickstreams via VQ-VAE, maps types to LLM persona tokens, fine-tunes agents on traces, and samples from merchant distributions to achieve 78% conversion-rate alignment on 42 held-out storefronts.
Grounding an LLM in verbalized transaction histories via Person–Environment prompting, continued pre-training, SFT, and GRPO yields stronger retail decision simulation than frontier models, with partial cross-domain transfer.
