During an uncharacteristically long video stream yesterday, OpenAI announced GPT-5, alongside a series of interface and usability improvements to its chatbot. Here’s everything new with ChatGPT.
One model to rule them all
After many years of confusion with similarly-named models imbued with overlapping abilities, OpenAI finally streamlined the user experience and trimmed down its model offerings to:
GPT-5
GPT-5 Thinking
GPT-5 Pro (limited to the US$200/mo plan)
OpenAI says that ChatGPT will intelligently decide how much time it should spend calculating the answer to the user’s prompt, but the user can manually select GPT-5 Thinking if they want to ensure a longer reasoning process.
And for the first time, free users will have access to the same model as Plus users, but with lower usage limits. Once those limits are reached, they’ll be switched to a ‘mini’ version of the model. The same applies to Plus users, though their limits will be more generous. In both cases, however, the exact thresholds remain unclear.
OpenAI also decided to deprecate all its other models. As a result, past conversations with older models “will automatically switch it to the closest GPT-5 equivalent. Chats with 4o, 4.1, 4.5, 4.1-mini, o4-mini, or o4-mini-high will open in GPT-5, chats with o3 will open in GPT-5-Thinking, and chats with o3-Pro will open in GPT-5-Pro (available only on Pro and Team).”
As for the Voice Mode, OpenAI says ChatGPT will keep on being powered by GPT-4o for now.
