Instruct field missing from generate UI for cloned Qwen3-TTS profiles

Author: jewelersforchildrenCreated Sep 15, 2026Updated Sep 15, 2026

The instruct parameter (natural-language delivery control) works correctly via the API for Qwen3-TTS cloned profiles — I confirmed this by calling POST /generate directly with "engine": "qwen" and an instruct string, and it worked exactly as expected.

However, the generate box in the app only shows the instruct textarea/slider when a Qwen CustomVoice profile is selected. It does not appear for cloned profiles using the Qwen3-TTS engine, even though the backend fully supports it for that engine too.

Steps to reproduce:

  1. Create a cloned voice profile using the Qwen3-TTS engine
  2. Select that profile in the generate box
  3. Notice there's no instruct/delivery-instructions field available

Expected: the instruct field should appear for any profile using the "qwen" engine (both CustomVoice and cloned Qwen3-TTS), not just CustomVoice.

Workaround: calling POST /generate directly with "engine": "qwen" and an instruct field works fine — this looks like a UI gating issue rather than a backend limitation.
