Removal of Manual AI Model Selector Has Caused Significant Damage to Paid Projects

I am posting this as formal feedback and notice regarding a critical change Base44 has recently made.

Until recently, Base44 allowed users to either:

Use a default AI model selection, or
Manually choose a specific coding model (Claude Pro, Gemini 3 Pro, GPT-5, etc.)

Many of us have paid thousands of dollars for access to this platform and intentionally built entire websites using one specific model, because different models produce different coding styles, structures, and assumptions.

Base44 has now removed the manual AI model selector and replaced it with an “intelligent” automatic selector. This change has had severe consequences.

The problem

The automatic selector is generating code that is incompatible with existing codebases built using specific models.
Previously working websites are now broken or non-functional.
In my case, I spent an entire day attempting to repair damage caused solely by this forced change, and my site is now completely non-functional.
The system continues to introduce new breaking changes every time code is generated.

This is not an edge case — this is a predictable and fundamental issue when mixing AI coding models mid-project without user control.

The bigger issue

This feature was a core capability relied upon when purchasing access.
Removing it mid-subscription materially changes the service that was paid for.
Refunds are being refused despite the platform actively breaking existing customer projects.

What needs to happen

At minimum, Base44 must:

Restore the manual AI model selector, or
Allow projects to be locked to a specific model, or
Provide refunds for users whose projects have been damaged by this change.

Final note

This post serves as formal notice that continuing to force an automatic AI selector — while refusing refunds — exposes Base44 to potential legal claims related to service alteration, damages, and misrepresentation.

I strongly urge Base44 to address this immediately. Restoring the manual AI model selector would resolve this issue for many users and prevent further damage.
