The replacement model is gpt-5.6-cyber. Why it matters: Any code calling gpt-5.4-cyber will fail after October 1, 2026. You have 19 days to complete the migration. What to do: Grep your codebase for 'gpt-5.4-cyber', update all references to 'gpt-5.6-cyber', test the replacement model's output against your use cases, and deploy before October 1. https://radar.trulysovereign.ai/items/2caf39c0-b116-452d-8c4f-e5c6119c3081 2caf39c0-b116-452d-8c4f-e5c6119c3081 Mon, 31 Aug 2026 04:10:47 GMT migrate OpenAI deprecations On August 26, 2026, OpenAI announced that whisper-1, gpt-4o-transcribe, gpt-4o-mini-transcribe, and gpt-4o-transcribe-diarize will be removed from the API on February 26, 2027. Recommended replacements are gpt-live-transcribe or gpt-transcribe. Why it matters: Any application using these four models for audio transcription will break on February 26, 2027 unless migrated to the replacement models. You have six months to test and deploy the migration. What to do: Grep your codebase for 'whisper-1', 'gpt-4o-transcribe', 'gpt-4o-mini-transcribe', and 'gpt-4o-transcribe-diarize'.
