[BUG] gpt-5-chat-latest unusable due to forced encrypted_reasoning in Responses API #9225
Description
Problem (one or two sentences)
Roo Code v3.31.2 always forces “encrypted reasoning” mode when using the OpenAI Responses API. Models like gpt-5-chat-latest do not support this feature, so any request immediately fails with an error.
https://github.com/RooCodeInc/Roo-Code/releases/tag/v3.31.2
[Migrate conversation continuity to plugin-side encrypted reasoning items using Responses API for improved reliability (thanks @hannesrudolph!)]
Context (who is affected and when)
Anyone using Roo Code with the OpenAI (native) provider and selecting gpt-5-chat-latest is affected. The issue appears as soon as they send any request, even in a simple project, making the model completely unusable in normal day-to-day coding.
