Instructions to use Vicen-te/qwen3.5-2b-sql with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use Vicen-te/qwen3.5-2b-sql with Transformers:

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

pipe = pipeline("text-generation", model="Vicen-te/qwen3.5-2b-sql")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Vicen-te/qwen3.5-2b-sql")
model = AutoModelForCausalLM.from_pretrained("Vicen-te/qwen3.5-2b-sql", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Qwen3.5-2B · SQL (merged)

Qwen/Qwen3.5-2B with a LoRA SQL adapter merged in. Drop-in replacement for the base — same architecture, same tokenizer, no PEFT runtime dependency.

Usage with transformers

from transformers import AutoModelForCausalLM, AutoTokenizer

tok = AutoTokenizer.from_pretrained("Vicen-te/qwen3.5-2b-sql")
model = AutoModelForCausalLM.from_pretrained("Vicen-te/qwen3.5-2b-sql", dtype="auto", device_map="auto")

Usage with vLLM

vllm serve Vicen-te/qwen3.5-2b-sql --max-model-len 4096 --served-model-name sql-ft

Training

Base model: Qwen/Qwen3.5-2B
Method: LoRA (rank=16, α=32) → merged via peft.merge_and_unload()
Dataset: Vicen-te/sql-create-context-mini — 300 train / 200 eval
Recipe: 3 epochs, bf16, effective batch 16, cosine LR 2e-4

Evaluation

Compared against the base model on a held-out 200-example split. See the project repo for the full report (executable accuracy, exact match, BLEU, latency, 4-bit quantization trade-off).

License
