+### Don't use ChatML syntax or special tokens with the chat completion endpoint
 
-Some customers try to use the [legacy ChatML syntax](../how-to/chat-markup-language.md) with the chat completion endpoints and newer models. ChatML was a preview capability that only worked with the legacy completions endpoint with the `gpt-35-turbo` version 0301 model. This model is [slated for retirement](../concepts/model-retirements.md). If you attempt to use ChatML syntax with newer models and the chat completion endpoint, it can result in errors and unexpected model response behavior. We don't recommend this use.

 | Error |Cause | Solution |

-| 400 - "Failed to generate output due to special tokens in the input." | Your prompt contains legacy ChatML tokens not recognized or supported by the model/endpoint. | Ensure that your prompt/messages array doesn't contain any legacy ChatML tokens. If you're upgrading from a legacy model, exclude all special tokens before you submit an API request to the model.|
