Open weights on the image, video and TTS side
OpenAI's gpt-image-1.x, sora-2, tts-1 and gpt-4o-mini-tts are closed checkpoints that run only inside OpenAI. Whisper is OpenAI's one open-source exception. deAPI runs open-weight models end-to-end (Flux family, Z-Image Turbo, open-source Whisper, open voice models) — the weights live publicly upstream, so the model itself is auditable and not locked inside a single vendor silo.
