How to use osunlp/QUEST-35B-MT with Transformers:

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

pipe = pipeline("text-generation", model="osunlp/QUEST-35B-MT")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForImageTextToText

processor = AutoProcessor.from_pretrained("osunlp/QUEST-35B-MT")
model = AutoModelForImageTextToText.from_pretrained("osunlp/QUEST-35B-MT")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.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(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

QUEST-35B-MT

This is the mid-training only checkpoint of QUEST-35B-A3B (Qwen3_5MoeForConditionalGeneration). It has not been fine-tuned with SFT or RL and therefore does not have the instruction-following or tool-use capabilities required to complete deep research tasks.

It is released as an intermediate artifact for research purposes (e.g., initializing further fine-tuning experiments or studying the effect of mid-training). If you need a usable deep research agent, please use QUEST-35B-MT+SFT or QUEST-35B-RL instead.

Training stage

Stage	Applied
Mid-training (MT)	✓
Supervised fine-tuning (SFT)	✗
Reinforcement learning (RL)	✗

Benchmark results

Not reported — this model lacks task-completion capability without SFT.

Quick start

from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "osunlp/QUEST-35B-MT"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id, device_map="auto", torch_dtype="auto",
)
