  "textContent": "nbo2:\n\n> Does the realtime model support temperature parameter?\n\nThere is no temperature control parameter or temperature echo return in the realtime session object. It was taken out of the non-beta version of realtime. There is no indication of what the model is being run at - or if there is complete oversight of the need to constrain temperature on voice models to avoid the very symptoms reported here.\n\nChat Completions has the model `gpt-audio-1.5`, where you can experiment with lowered temperature and see consistency when going even lower than the default 0.8 of 0.6-1.0 range you previously had, but where as low as “`0`” can be problematic and can have the AI start generating silence. No 2.0 version there.",
