# DistillAgent-PaperQA-3B
|
| 20 |
+
|
| 21 |
+
DistillAgent-PaperQA-3B is a compact agentic QA model distilled from tool-using trajectories for question answering over scientific papers (QASPER).
|
| 22 |
+
|
| 23 |
+
It is fine-tuned from `Qwen/Qwen2.5-3B-Instruct` using LoRA/rsLoRA with constrained Thought/Action/Observation/Final Answer trajectories.
|
| 24 |
+
|
| 25 |
+
## Highlights
|
| 26 |
+
|
| 27 |
+
- Small model with practical agentic behavior on research-paper QA.
|
| 28 |
+
- Outperforms base model in our QASPER 200-sample evaluation.
|
| 29 |
+
|
| 30 |
+
## Model Details
|
| 31 |
+
|
| 32 |
+
- Base model: `Qwen/Qwen2.5-3B-Instruct`
|
| 33 |
+
- Training: LoRA / rsLoRA SFT
|
| 34 |
+
- Domain: scientific paper QA (QASPER)
|
| 35 |
+
- Inference style: constrained ReAct + section lookup
|
| 36 |
+
|
| 37 |
+
## Evaluation Summary (QASPER, 200 samples)
|
| 38 |
+
|
| 39 |
+
| Model | EM | Mean F1 | Mean hops | Mean latency |
|
| 40 |
+
|---|---:|---:|---:|---:|
|
| 41 |
+
| DistillAgent-PaperQA-3B (SFT) | 14.5% | 0.2425 | 2.36 | 37.28s |
|
| 42 |
+
| Base Qwen2.5-3B-Instruct | 9.0% | 0.1650 | 3.00 | 20.04s |
|
| 43 |
+
|
| 44 |
+
Notes:
|
| 45 |
+
- Hops and latency depend on runtime harness and hardware.
|
| 46 |
+
- Main quality outcome: SFT > base on EM and F1.
|
| 47 |
+
|
| 48 |
+
## Intended Use
|
| 49 |
+
|
| 50 |
+
- QA over scientific/technical papers with section-level lookup or retrieval.
|
| 51 |
+
- Research and educational workflows for compact agentic model distillation.
|
| 52 |
+
|
| 53 |
+
## Limitations
|
| 54 |
+
|
| 55 |
+
- Sensitive to runtime prompt/harness format.
|
| 56 |
+
- Multi-hop behavior can increase latency.
|
| 57 |
+
- Should not be used as sole source for high-stakes scientific or medical decisions.

## Usage (Transformers)
|
| 60 |
+
|
| 61 |
+
```python
|
| 62 |
+
from transformers import AutoTokenizer, AutoModelForCausalLM
|
| 63 |
+
import torch
|
| 64 |
+
|
| 65 |
+
repo_id = "QuantumCuddle/DistillAgent-PaperQA-3B"
|
| 66 |
+
|
| 67 |
+
tokenizer = AutoTokenizer.from_pretrained(repo_id)
|
| 68 |
+
model = AutoModelForCausalLM.from_pretrained(
|
| 69 |
+
repo_id,
|
| 70 |
+
torch_dtype=torch.float16,
|
| 71 |
+
device_map="auto",
|
| 72 |
+
)
|
| 73 |
+
|
| 74 |
+
prompt = "QUESTION: What baseline method is used?\nAVAILABLE PAPER SECTIONS:\n1. Abstract\n2. Methods\n..."
|
| 75 |
+
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
|
| 76 |
+
out = model.generate(**inputs, max_new_tokens=256, temperature=0.0)
|
| 77 |
+
print(tokenizer.decode(out[0], skip_special_tokens=True))
|
| 78 |
