The hidden truth about AI chatbot costs

We ve been testing Fabio AI Chatbot on several real websites using ChatGPT 5.4:

• a main website Fabio-Plugins.com

• a WooCommerce demo store with 1,000 products : https://fabio-plugins.com/demo_shop

• a cooking blog with 570 pages : https://fabio-plugins.com/demo_h...

• BBPress forums : https://fabio-plugins.com/support/

Glad to announce that v3.5.7 of Fabio AI Chatbot with two meaningful upgrades focused on performance and user experience.

New model flexibility
You can now switch to ChatGPT 5.5 for more advanced reasoning and improved outputs while keeping 5.4 as the default for stability and cost efficiency. Choose what fits your use case best.

Today we share tests from our users the kind of questions people actually ask when they want to challenge an AI chatbot.

Here s one particularly interesting example.

A tester asked the exact kind of question a real visitor would:

Dear Product Hunt users,

Following a specific request from a user, we ve just shipped version 3.5.6 of Fabio AI Chatbot, and this update is a big step forward if you're running a directory website.

I ve been experimenting with a simple way to make BBpress forum content easier to use for visitors.

The setup is pretty straightforward and only takes a few steps:

I wanted to share a quick benchmark we ran while building Fabio AI Chatbot, testing how different LLMs behave in a real product search scenario.

Instead of synthetic benchmarks, this was done on an actual WooCommerce store (~1000 products), using the exact same prompt across models.

To better understand how different AI models behave inside Fabio AI Chatbot, we ran a simple test on our kitchen troubleshooting demo site : https://fabio-plugins.com/demo_h... with the 3 latest ChatGPT models from @OpenAI.

The user question

The visitor typed a short and imperfect request :

Fabio AI Chatbot 3.5.2 is live!

We ve just released version 3.5.2 of Fabio AI Chatbot, with two important improvements for WordPress site owners.

Choose your ChatGPT model
You can now select between the three latest ChatGPT models directly in the plugin:
GPT 5.4 best overall reasoning and response quality
GPT 5.4 Mini balanced speed and cost
GPT 5.4 Nano ultra-fast and lightweight

Hey Product Hunt

We recently ran a simple test inside Fabio AI Chatbot (our WooCommerce plugin connected to stores with a 1000 products catalogs).

We asked different AI models the exact same product query:
