Simulation Benchmark for LLM Agents in Retail

In the dizzying advance of artificial intelligence, agents based on large language models (LLMs) have demonstrated an impressive ability to solve limited tasks in short horizons. However, when faced with dynamic and long-lasting environments, such as running a supermarket, their performance becomes uncertain. This is where RetailBench comes in, a data-driven simulator that allows these agents to be evaluated in realistic retail operation scenarios. The platform models a store's management as a partially observable decision process, where agents must manage pricing, replenishment, supplier selection, shelf assortment, inventory aging, customer feedback, external events, and cash flow constraints. All this during simulations that can last more than a thousand days. The proposal is not only a test bed, but a mirror that reflects the strengths and weaknesses of today's LLMs when they are required to be strategic coherence in the long term.

The results obtained after evaluating seven contemporary models for 180 days are revealing. Only a small subset manages to complete the simulation horizon, and none come close to the performance of an oracle policy that is insider. The gaps are notable in both ending net worth and cumulative sales. By delving deeper into the behavior of agents, three main causes are identified: incomplete acquisition of evidence, superficial decisions that ignore the historical context and, above all, the absence of a consistent long-term policy. Not only do these findings have implications for academic research, but they offer valuable lessons for companies looking to implement artificial intelligence into their operations. Especially those that require autonomous and sustained decision-making over time, such as supply chain management or inventory optimization.

From a business perspective, RetailBench underscores the need for AI systems that not only respond to immediate stimuli, but also build mental models of the environment and plan for the future. This is where companies like Q2BSTUDIO bring their expertise in developing artificial intelligence for companies, integrating AI agents capable of learning from prolonged simulations and adapting their strategies. Creating these systems requires combining reinforcement learning techniques with language models that understand the business context. It's not just about throwing a prompt, but about designing architectures that allow agents to remember past interactions, assess consequences, and adjust their policies in real time. Q2BSTUDIO, as a technology partner, offers tailor-made software solutions that implement these principles in sectors such as retail, logistics and manufacturing, ensuring that AI is not only reactive, but strategically sound.

The infrastructure that supports these agents is also critical. To handle simulations of thousands of days and process large volumes of data, you need a robust and scalable cloud platform. Q2BSTUDIO provides AWS and Azure cloud services that enable the deployment of simulation environments with high availability and low cost. In addition, integration with business intelligence tools such as Power BI makes it easier to visualize results and make decisions based on real data. The combination of AI agents, cloud computing, and business intelligence creates an ecosystem where companies can experiment with what-if scenarios before implementing real-world changes. Thus, RetailBench is not only an academic benchmark, but a demonstration of how current technology can be applied to solve complex management problems.

Another relevant aspect is security and cybersecurity in autonomous environments. When agents make financial and operational decisions, any vulnerability can translate into economic losses or reputational risks. For this reason, Q2BSTUDIO also offers cybersecurity and pentesting services to ensure that AI systems are robust against attacks and errors. In a world where AI agents are beginning to manage inventory and prices autonomously, trust and security are fundamental pillars. Penetration testing and code audits help identify weaknesses before they are exploited, something that any company adopting this technology should seriously consider.

The gap observed between LLMs and oracle policy in RetailBench also points towards the need to develop custom applications. Every business has unique business rules, cash constraints, and strategic goals. A generic model, no matter how powerful, cannot be adapted to all realities. This is where custom software becomes a competitive advantage. Q2BSTUDIO helps companies design and implement AI systems that fit their specific processes, from supplier management to customer satisfaction analysis. Personalization allows you to incorporate variables that a standard model ignores, such as seasonality, local promotions, or historical consumer behavior. Thus, the agent not only learns from the simulation, but aligns with the vision of the business.

The future of autonomous agents lies in integrating continuous learning and long-term planning. RetailBench shows that we are still far from perfect AI, but it also reveals the way forward. Companies that want to get ahead of the curve must invest in research and development, but also in platforms that allow these solutions to scale. Q2BSTUDIO, with its expertise in business intelligence and Power BI services, offers the tools to measure the impact of these agents in real time. Combining simulations like RetailBench with executive dashboards allows managers to understand not only what decision the agent made, but why they made it. This level of transparency is essential to build trust and to adjust policies where necessary.

In conclusion, RetailBench is not just an academic exercise, but a catalyst for rethinking how we design autonomous systems in real-world environments. The evaluation of long-term LLMs exposes their limitations, but also inspires new solutions. Companies like Q2BSTUDIO are at the forefront, offering artificial intelligence, cloud services and custom software development so that organizations can harness the potential of AI agents without falling into detected errors. The key is not to look for shortcuts, but to build systems that learn, remember, and plan with the same vision as an experienced manager. The road is long, but each simulation brings us one step closer to reliable autonomy.
