How Fabio AI Chatbot compares AI models on a real WooCommerce product search test
We tested multiple AI models available in Fabio AI Chatbot on the same shopping query to see which ones feel most helpful, selective, and convincing for online shoppers.
We ran this test on a 1,000-product demo WooCommerce store organized into 4 categories. We deliberately chose a broad, realistic shopping question — the kind of request a real visitor might type when they know what they want, but not exactly which product to pick.
8 AI models
We compared 8 different AI models, all available by default in the standard settings of Fabio AI Chatbot.
Real WooCommerce catalog
All answers were generated against the same store data, so differences mainly come from the model behavior, response style, and recommendation logic.

At a glance
Main takeaway by model family
Each family showed a distinct shopping style: broader exploration, stricter filtering, or more premium one-product recommendations.
Most polished overall
Strong user experience, balanced recommendations, and a reassuring tone for shoppers comparing several close matches.
Strong product matching
The Mistral models consistently found the exact matching product, which is a very good signal for e-commerce product search.
Different sales styles
One model felt more premium and focused, while the other supported broader browsing and product discovery.
ChatGPT models
What did ChatGPT models answer?
From a user’s point of view, the 3 ChatGPT models feel different in how they handle a limited product match.
ChatGPT 5.4 gives the most polished user experience overall. It is slower, but it reads like a confident assistant: it presents the available options clearly and ends with a strong recommendation for the exact 10-hour match, while still offering nearby alternatives. For a shopper, Nano feels more strict, Mini feels more expansive, and 5.4 feels the most complete and reassuring.
Best overall user experience
The most polished answer of the three, with clear product framing, nearby alternatives, and a strong final recommendation.

Broader shopping helper
ChatGPT 5.4 Mini feels more like a broad shopping helper, listing several nearby alternatives quickly, but with less filtering precision, so the user may feel it is a bit less selective.

Fast and disciplined
ChatGPT 5.4 Nano is fast and fairly disciplined: it clearly identifies the closest valid options and explains why some cheaper products do not fully meet the 10-hour requirement.

Mistral models
What did Mistral models answer?
These tests were especially promising for store owners looking for accurate product matching in a shopping assistant.
These 3 Mistral tests are promising for e-commerce: all models found the exact matching product instead of suggesting weak alternatives, which is what store owners want from an AI shopping assistant. For entrepreneurs evaluating AI for online stores, the takeaway is simple: even smaller Mistral models can already handle product search well, but the perceived quality also depends on the final interface and formatting.
Cleanest overall experience
Mistral Large 3 delivered the cleanest overall experience with both speed and clarity.

Correct but less polished
Mistral Medium 3.1 gave the right answer but with a less polished rendering.

Fastest and already effective
Mistral Small 3.2 was the fastest and already very effective.

Gemini models
What did Gemini models answer?
Gemini showed two distinct recommendation styles, depending on whether the goal is focused selling or broader catalog exploration.
Focused premium recommendation
From an e-commerce store owner’s perspective, Gemini 3.1 Pro feels more like a focused sales assistant, recommending a single product in a more polished and conversational way, but with a noticeably slower response time.

Better for product discovery
Gemini 3 Flash feels more suited to broad product discovery: it highlights one main match, then suggests other relevant options, which can help keep shoppers engaged with the catalog.

Which Gemini style fits your store?
In practice, the choice depends on the role you want your chatbot to play. Gemini 3 Flash is better for showcasing multiple products and supporting browsing, while Gemini 3.1 Pro is better for a more premium, one-product recommendation style.
