ChatGPT Desktop: Work/Codex voice UI is missing in API key authentication mode while Chat voice remains available

Summary

When ChatGPT Desktop is authenticated using an OpenAI API key (via codex login --with-api-key), Chat voice remains available, but the Work and Codex views do not display any voice input button.

Environment

• macOS
• ChatGPT Desktop 1.2026.184
• Apple Silicon
• Authenticated using API key

Expected

Voice should either be available consistently across Chat, Work and Codex, or the UI should indicate that API-key authentication does not support Work/Codex voice.

Actual

• Chat: Voice button visible
• Work: No voice button
• Codex: No voice button

Diagnostics

• voiceAvailable = 1 in RemoteFeatureFlags.
• No local preference disabling voice found.
• com.openai.codex contains only UI/update preferences.
• Logs contain backend responses including 403 /celsius/ws/user and 500 /wham/tasks/list.
• Chat voice continues to work normally.
• ChatGPT Desktop and Codex CLI appear to share authentication state after codex login --with-api-key.

Question: Is this expected behavior for API-key authentication, or a bug/regression?
