Libraries

How to use latkes/rankalign-v7-qwen3.5-9b-ifeval-s1-ep2 with Transformers:

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

pipe = pipeline("text-generation", model="latkes/rankalign-v7-qwen3.5-9b-ifeval-s1-ep2")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForMultimodalLM

tokenizer = AutoTokenizer.from_pretrained("latkes/rankalign-v7-qwen3.5-9b-ifeval-s1-ep2")
model = AutoModelForMultimodalLM.from_pretrained("latkes/rankalign-v7-qwen3.5-9b-ifeval-s1-ep2")
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]:]))

RankAlign v7 — Qwen3.5-9B — ifeval — setting s1 (SFT label-only), epoch 2

Merged (base + LoRA) Qwen3.5-9B fine-tuned on ifeval-concat with RankAlign setting s1 (SFT label-only baseline: no preference/ranking loss). Final checkpoint of a 3-epoch run (ep2). delta = 0.84 (delta-bins scheme, 10 bins).

Base model: Qwen/Qwen3.5-9B
LoRA: r=16, alpha=32, dropout=0.1, targets q/k/v/o/gate/up/down_proj (see adapter/)
Trained with scripts/run_qwen35_cell.sh ifeval s1 (no-upload-hf, no-wandb)
Eval (held-out ifeval test prompts, n=20, NO_BASE): gen_roc Raw 52.0 / TC(self) 73.1; val_roc 57.5; val_acc 44.7
