How to use XHToken/Spark-X2.5-4B with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="XHToken/Spark-X2.5-4B", trust_remote_code=True)
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate

Thank you for your work, and publishing this great little model!

I worked on a quantization and chat template to improve its performance for agentic coding, and found that there were fixes to be made in the chat template.

Published my work including my fixed and changed chat template at https://huggingface.co/peculiar-ragdoll/Sharp-Spark-X2.5-4B-GGUF so feel free to check it out and see if you want to validate and adopt any of the modifications :) If you feel this reads as self-promo I won't mind if you delete this discussion, no worries!

Kind regards,
Saga
