Qwen3.5-0.8B-Function-Calling-xLAM

A LoRA fine-tune of Qwen/Qwen3.5-0.8B.

Base model	Qwen/Qwen3.5-0.8B
Architecture	Qwen3_5ForCausalLM
Parameters	752M
Method	LoRA supervised fine-tuning via Unsloth + TRL
License	apache-2.0 (inherited from the base model)

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "ermiaazarkhalili/Qwen3.5-0.8B-Function-Calling-xLAM"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id, dtype='auto', device_map='auto')

messages = [{"role": "user", "content": "Explain gradient checkpointing in two sentences."}]
inputs = tokenizer.apply_chat_template(
    messages, add_generation_prompt=True, return_tensors='pt'
).to(model.device)

outputs = model.generate(inputs, max_new_tokens=256)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Training configuration

Setting	Value
LoRA rank (r)	16
LoRA alpha	32
Learning rate	0.0001
Epochs	1
Effective batch size	8 (2 x 4 grad accum)
Base precision	4-bit (QLoRA)

Limitations

• No benchmark evaluation has been run on this checkpoint. The only reported numbers are training-loss observations.
• Inherits the biases, knowledge cutoff and failure modes of the base model.
• Fine-tuned on a single instruction-following dataset; behaviour outside that distribution is untested.
• LoRA adapters were merged into the base weights, so the merged model cannot be detached from this fine-tune.

Reproducing

Trained by notebooks/xlam_function_calling_qwen3.5-0.8b.ipynb, executed non-interactively with papermill on a SLURM H100 partition (Unsloth + TRL, LoRA).
