+- Previously, in `HuggingFaceClient`, Hugging Face models were loaded with `trust_remote_code=True` by default. This was a security risk as it permitted executing arbitrary code from the model repositories. This will no longer be done. If needed, `trust_remote_code` must be explicitly set in the `args` field in `model_deployments.yaml` for Hugging Face models. (#4054)
+- Previously, responses from models on the Mistral AI API were tokenized locally locally. These responses will no longer be tokenized. (#4084)
