microsoft/phi-4-onnx · Chat format and special token problems

Hi,

I think there is a problems with the chat format and/or special tokens. When running the model like stated on the model card, so using Microsoft's "phi3-qa.py" script, the generation will sometimes not stop at "<|end|>" and continue with a hallucinating the next prompt. The following example is reproduceable:

$ python phi3-qa.py -m /opt/data/models/Phi-4-onnx/gpu/gpu-int4-rtn-block-32 -e cuda

I'm trying to understand the concept of a "soul" in different philosophical and religious contexts. Can you explain how the idea of a soul is viewed in various traditions, and how these views might influence ethical or moral perspectives?<|end|>

The concept of a "soul" varies significantly across different philosophical and religious traditions, each offering unique perspectives that can influence ethical and moral viewpoints. Here's an overview of how some major traditions view the soul:

1. **Christianity**:
   - **View**: In Christianity, the soul is considered the immortal essence of a human being, created by God. It is distinct from the body and is believed to go to heaven or hell after death based on one's faith and actions.
   - **Ethical Influence**: The belief in an^C  --control+c pressed, aborting generation--

I'm also confused. I used Phi-4 GGUF before and noticed the chat format changed there compared to Phi-3. E.g., it was expecting "<|im_end|>" tokens in the chat format. This one now seems to expect the same tokens like Phi-3. Although in the special_tokens_map.json it is defining "<|im_end|>" as EOS token. How could that be? I thought chat format is inherently anchored into a model by the training.

I would appreciate any help!
