 ### Model resolution
 
 vLLM loads HuggingFace-compatible models by inspecting the `architectures` field in `config.json` of the model repository
@@ -41,37 +43,6 @@ Nevertheless, our model resolution may fail for the following reasons:
 - Unofficial repositories refer to a model using alternative names which are not recorded in vLLM.
 - The same architecture name is used for multiple models, creating ambiguity as to which model should be loaded.
 
-In those cases, vLLM may throw an error like:
-
-```text

-This error means that vLLM failed to import the model file. Usually, it is related to missing dependencies or outdated
-binaries in the vLLM build. Please read the logs carefully to determine the real cause of the error.

 To fix this, explicitly specify the model architecture by passing `config.json` overrides to the `hf_overrides` option.
 For example:
