GPT-5 Compatibility for BYOK Users

Version: 1.19.30, Date: February 5, 2026

GPT-5 compatibility is now correct for BYOK users. OpenAI’s GPT-5 models were returning errors due to two API parameter incompatibilities. Both have been resolved, so all GPT-5 variants now work for prompt generation and analysis when you use your own API key. The rest of this post is grouped by app area.

Across the App

• Fixed: GPT-5 models (gpt-5, gpt-5-mini, gpt-5-turbo) were returning errors in Builders and Analyzers due to an unsupported token limit parameter and a temperature setting these models do not accept. Both have been corrected. All GPT-5 variants now work correctly for prompt generation and analysis when using BYOK (Bring Your Own Key).
