AI Model Selector Comes to Prompt Designer

April 9, 2026

The Prompt Designer now supports AI model selection, bringing it in line with the Prompt Builder and Analyzers. You can choose the model that powers your prompt generation, with credits tracked and enforced correctly for each provider, no surprises.

New Features

• Multi-Provider Model Selection in Prompt Designer — You can now choose which AI model generates your prompt output directly from the Designer interface. Supported providers include OpenAI, Anthropic, Google, and xAI. Each model charges the appropriate credits for what it uses, so your quota always reflects actual cost.
• BYOK Support in Prompt Designer — Bring Your Own Key is now fully supported in the Designer, consistent with how it works across the rest of the platform.

Improvements

• Consistent Model Selection Experience — The AI Model Selector in the Prompt Designer now matches the established pattern already in place for the Prompt Builder and Analyzers, giving you a uniform experience regardless of which tool you’re working in.
• Model Validation Before Generation — If a model selection is invalid or missing, you’ll see a clear, friendly error before generation runs — no silent failures or unexpected results.
