How Cimulate Builds Your CommerceGPT
December 1, 2025
Every retailer is unique: your products, your customers, and your goals. That’s why off-the-shelf AI solutions or generic large language models can’t deliver the personalized, contextual commerce experiences your brand deserves. Cimulate takes a different approach: we create your brand’s own CommerceGPT, a large language model purpose-built for your business.
With CommerceGPT, your AI understands your catalog, anticipates your shoppers’ intent, and adapts to your business objectives. Here’s how we build it:
Step 1: Gathering Your Data and Creating Shopping Personas
We begin with your products and customer data. This allows us to create realistic shopper personas. These personas carry the attributes your customers do – they’re modeled off attributes like socio-economic status, location, areas of interest, tendencies to value shop, and a host of other factors.
Step 2: Simulating Real Shopper Behavior
Next, we have these personas shop thousands of times. This is a simulation exercise, and each shopper journey generates synthetic behavioral data, revealing what drives conversions, where shoppers hesitate, and which paths lead to successful purchases.
This process, which we call Distillation via Simulation, extracts commerce-specific intelligence from general-purpose LLMs, transforming it into insights that are highly specific to your business and your customers.
Step 3: Fine-Tuning Your CommerceGPT
We’ve created the basis for your model, and next we fine-tune your model with your real customer and product data, including any knowledge base how-to articles. This ensures your CommerceGPT understands your catalog structure, your brand’s language, and the intent behind every shopper action. It becomes an AI that doesn’t just answer questions. It acts like a virtual merchandiser trained on your brand.
Step 4: Delivering Contextual Commerce
The final model powers every digital interaction, search, recommendations, browsing, or conversational experiences, ensuring results are fast, relevant, and context-aware. Because it’s trained specifically on your business, CommerceGPT adapts in real-time, evolving as your products, customers, and strategies change.
The Result: Smarter Commerce That Converts
With Cimulate, your CommerceGPT is more than a tool; it’s an extension of your brand, designed to deliver higher conversion, deeper engagement, and more meaningful shopper experiences. Smarter search leads to better discovery, more purchases, and stronger long-term customer relationships.
