Fix: The Previous Model used in this conversation is Unavailable. We’ve switched you to the latest default model in ChatGPT

Fix The previous model used in this conversation is unavailable.

If you’re a regular user of OpenAI’s ChatGPT, you may have come across a situation where the model in your ongoing chat conversation changes abruptly.

One moment you’re deep into a discussion with ChatGPT-4, and the next, you get a message that reads: The previous model used in this conversation is unavailable. We’ve switched you to the latest default model. Quite jarring, right?

This sudden switch can disrupt the continuity and quality of your conversation. ChatGPT-4, with its enhanced capabilities, might be giving you incredibly nuanced and insightful responses.

But once you’re switched to ChatGPT-3.5, you could see a noticeable decline in the complexity and depth of the AI’s responses. This can be frustrating, especially if you’re in the middle of an important chat.

Causes of the Problem of Previous Model Used Unavailable

So why does this model switch happen? There could be a few reasons:

  1. Incompatibility between models: Each model has its own set of features and capabilities. ChatGPT-4 and ChatGPT-3.5 aren’t just different in terms of their functionality, they’re also built differently. This can sometimes lead to incompatibility issues during a conversation.
  2. Server difficulties: The server hosting the models can encounter technical issues, which may force a switch to a different model.
