GPT-5 Model Compatibility for BYOK Users
February 5, 2026
A targeted fix to ensure OpenAI’s GPT-5 models work correctly when using your own API key.
Bug Fixes
- Fixed GPT-5 models failing in Builders and Analyzers. GPT-5 models (gpt-5, gpt-5-mini, gpt-5-turbo) were returning errors due to two API parameter incompatibilities — an unsupported token limit parameter and a temperature setting these models don’t accept. Both have been resolved, so all GPT-5 variants now work correctly for prompt generation and analysis when using BYOK (Bring Your Own Key).
