AIGP: An LLM-Based Framework for Long-Term Value Alignment in E-Commerce Pricing

2026-06-25 · Source: Artificial Intelligence · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Data Science & Analytics · Depth: Expert, quick

Summary

The AIGP framework addresses limitations in traditional e-commerce dynamic pricing, such as poor interpretability, underutilization of unstructured data, and misalignment with long-term objectives like cumulative Gross Merchandise Value (GMV) and Return on Investment (ROI). AIGP utilizes a Large Language Model (LLM) prompted with domain knowledge, structured data, and textual context to generate interpretable, knowledge-aware pricing decisions. For efficient deployment, supervised fine-tuning is used for knowledge distillation. A core component is the Long-Term Value Estimator (LTVE), trained via offline reinforcement learning, which acts as a reward model to score pricing actions and select preference pairs for Direct Preference Optimization (DPO). This aligns the pricing policy with long-term business goals. Offline evaluations and large-scale online A/B tests on Tao Factory showed significant improvements over 14 days: +13.21% in GMV, +7.59% in ROI, and +8.20% in milestone achievement rate, alongside transparent pricing rationales.

Key takeaway

For AI/ML Directors overseeing e-commerce pricing strategies, AIGP offers a compelling approach to overcome traditional model limitations. You should consider integrating LLM-based frameworks with offline reinforcement learning, specifically Direct Preference Optimization, to enhance pricing interpretability and ensure alignment with long-term business objectives like GMV and ROI. This method, demonstrated by +13.21% GMV gains on Tao Factory, provides transparent rationales, crucial for strategic decision-making and achieving sustained growth.

Key insights

AIGP uses LLMs and offline RL to align e-commerce pricing with long-term value, improving GMV and ROI.

Principles

• LLMs enhance pricing interpretability.
• Offline RL aligns pricing with long-term goals.
• Knowledge distillation improves LLM deployment.

Method

AIGP prompts an LLM with data for pricing, then uses an LTVE (trained via offline RL) as a DPO reward model to optimize for long-term business objectives.

In practice

• Apply LLMs for contextual pricing.
• Use DPO with RL for long-term alignment.
• Fine-tune LLMs for efficient deployment.

Topics
