Paper-Summarizer-Nemotron-12B

A fine-tuned Nemotron-12B model specialized for generating structured summaries of scientific research papers in standardized JSON format with superior throughput.

Model Description

This model is part of Project AELLA, developed in collaboration with LAION and Wynd Labs to democratize access to scientific knowledge by creating structured summaries of research papers at scale.

Base Model: NVIDIA Nemotron 12B (Hybrid Mamba-Transformer) Training Data: 110,000 curated research papers Performance: Achieves 71.3% accuracy on QA evaluation Throughput: 2.25× faster than Qwen3-14B variant

This generates comprehensive structured summaries in a JSON format. The papers are either classified as SCIENTIFIC_TEXT, PARTIAL_SCIENTIFIC_TEXT, or NON_SCIENTIFIC_TEXT. The fields extracted are key research elements such as methodology, results, claims, and limitations.

The model supports papers up to 131K tokens and is optimized for large-scale batch processing with high throughput (0.97 requests/sec).

Usage

Serving the Model

Note: This model requires a custom chat template for proper reasoning token handling.

Making Requests

python

import requests

# System prompt (required)
system_prompt = """[Insert the full system prompt from the prompt.txt file -
see the full prompt in the model repository]"""

# User prompt: the paper text to summarize
paper_text = """
Title: Your Paper Title
Authors: Author 1, Author 2
Abstract: ...
[Full paper content]
"""

# API request
response = requests.post(
    "http://localhost:8000/v1/chat/completions",
    json={
        "model": "inference-net/Paper-Summarizer-Nemotron-12B",
        "messages": [
            {"role": "system", "content": system_prompt},
            {"role": "user", "content": paper_text}
        ],
        "temperature": 0.2
    },
    timeout=600
)

result = response.json()
# Note: Response may include reasoning tokens wrapped in <think></think>
# These are automatically stripped by the chat template
summary = result["choices"][0]["message"]["content"]
print(summary)

System Prompt

The model requires the same system prompt as the Qwen3-14B variant. The prompt instructs the model to:

Classify the text as SCIENTIFIC_TEXT, PARTIAL_SCIENTIFIC_TEXT, or NON_SCIENTIFIC_TEXT
Extract structured information including:
- Title, authors, publication year
- Research context and hypotheses
- Methodological details
- Key results with quantitative data
- Claims with supporting evidence
- Limitations and ethical considerations

The full system prompt is available in the model repository's prompt.txt file.

Output Format

The model outputs a single valid JSON object with this structure:

json

{
  "article_classification": "SCIENTIFIC_TEXT",
  "reason": null,
  "summary": {
    "title": "",
    "authors": "",
    "publication_year": null,
    "field_subfield": "",
    "executive_summary": "",
    "research_context": "",
    "methodological_details": "",
    "key_results": "",
    "claims": [...],
    "contradictions_and_limitations": "",
    ...
  }
}

Performance

LLM-as-a-Judge Evaluation

Score: 4.095/5.0
Comparison: Slightly behind Qwen3-14B (4.207) but still high quality

QA Dataset Evaluation

Accuracy: 71.3%
Comparison: Strong performance, suitable for batch processing

Throughput (8×H200 node)

Requests/sec: 0.97 (2.25× faster than Qwen3-14B)
Input Tokens/sec: 16,943.69
Output Tokens/sec: 4,880.76
Single Request Tokens/sec: 76.17

Cost Efficiency

Processing 100M papers: ~$45,000 (vs $100,000 for Qwen3-14B, $5M+ for GPT-5)
Ideal for: Large-scale batch processing where throughput matters

Training Details

Training Set: 100,000 papers (same as Qwen3-14B)
Validation Set: 10,000 papers
Average Paper Length: 81,334 characters
Architecture: Hybrid Mamba-Transformer for high throughput
Training Approach: Post-training on summaries generated by frontier models

When to Use This Model

Choose Nemotron-12B if:

Processing large batches (100K+ papers)
Throughput and cost are primary concerns
Accuracy in the 70-75% range is acceptable
Running on GPU infrastructure with parallel processing

Choose Qwen3-14B if:

Need highest possible accuracy (73.9% vs 71.3%)
Processing smaller batches or single papers
Quality is more important than speed

Limitations

May generate subtle factual errors (hallucinations) for fine-grained details
Context limit (131K tokens) may truncate extremely long documents
Unified schema may not capture all domain-specific nuances
Summaries are research aids, not replacements for primary sources in high-stakes scenarios
Slightly lower accuracy than Qwen3-14B variant
