OpenAI's athyuttamre announced a major ChatGPT Voice update: voice can now use GPT-5.6 Sol and GPT-6 Astra. Users can select any model and effort level — including GPT-5.6 Sol or GPT-6 Astra on Pro — and voice will invoke the chosen model when it needs to search or reason. Early user feedback in the replies notes it still doesn't seem to follow (or pass down) custom instructions.
