qwen3-4b-hermes-tooluse

Model Card for qwen3-4b-hermes-tooluse

This model is a fine-tuned version of Qwen/Qwen3-4B. It has been trained using TRL.

Quick start

from transformers import pipeline

question = "If you had a time machine, but could only go to the past or the future once and never return, which would you choose and why?"
generator = pipeline("text-generation", model="lewtun/qwen3-4b-hermes-tooluse", device="cuda")
output = generator([{"role": "user", "content": question}], max_new_tokens=128, return_full_text=False)[0]
print(output["generated_text"])

Training procedure

This model was trained with SFT.

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = 'lewtun/qwen3-4b-hermes-tooluse'
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)

For non-causal architectures, replace AutoModelForCausalLM with the appropriate AutoModel class.
