2 AI tools and 2 AI agents in the Intelloro directory are built on or use GPT-4.1. GPT-4.1 can also be chosen in 4 products that let you pick the model you run. See the full list on this page — each links to its detailed profile.

Where can I use GPT-4.1?

4 products in the Intelloro directory list GPT-4.1 among the models you can choose (bring-your-own-model and multi-model products). They are shown separately from adopters, because offering a model is not the same as being built on it.

How is GPT-4.1 adoption tracked?

Adoption is derived from the models each product names on its own website. A tool or agent is counted when it lists GPT-4.1 as a base model (built on) or a model it uses. Bring-your-own-model aggregators are excluded so they do not inflate the count.

Where does the GPT-4.1 adoption data come from?

From each product's own website: a product is listed here when its own pages say it is built on or uses GPT-4.1. It updates as products change their pages and as the directory grows.
