AstroSage-Llama-3.1-8B is a domain-specialized natural-language AI assistant tailored for research in astronomy, astrophysics, and cosmology. Trained on the complete collection of astronomy-related arXiv papers from 2007-2024 along with millions of synthetically-generated question-answer pairs and other astronomical literature, AstroSage-Llama-3.1-8B demonstrates excellent proficiency on a wide range of questions. This achievement demonstrates the potential of domain specialization in AI, suggesting that focused training can yield capabilities exceeding those of much larger, general-purpose models. Model Details

Base Architecture: Meta-Llama-3.1-8B
Base Model: Meta-Llama-3.1-8B
Parameters: 8 billion
Training Focus: Astronomy, Astrophysics, Cosmology, and Astronomical Instrumentation
License: Llama 3.1 Community License
Development Process:
    Continued Pre-training (CPT) on astronomical literature
    Supervised Fine-tuning (SFT) on QA pairs and instruction sets
    Model merging with Meta-Llama-3.1-8B-Instruct (75% CPT+SFT / 25% Meta-Instruct)

Using the model

import torch from transformers import AutoModelForCausalLM, AutoTokenizer

Load the model and tokenizer

model = AutoModelForCausalLM.from_pretrained("AstroMLab/AstroSage-8b", device_map="auto") tokenizer = AutoTokenizer.from_pretrained("AstroMLab/AstroSage-8b")

Function to generate a response

def generate_response(prompt): inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

outputs = model.generate(
    **inputs,
    max_new_tokens=128,
    do_sample=True,
    pad_token_id=tokenizer.eos_token_id,
)
response = outputs[0][inputs['input_ids'].shape[-1]:]
decoded = tokenizer.decode(response, skip_special_tokens=True)

return decoded

Example usage

prompt = """ You are an expert in general astrophysics. Your task is to answer the following question: What are the main components of a galaxy? """ response = generate_response(prompt) print(response)

Model Improvements and Performance

AstroSage-Llama-3.1-8B shows remarkable performance improvements: Model Score (%) AstroSage-Llama-3.1-8B 80.9 GPT-4o 80.4 LLaMA-3.1-8B 73.7 Gemma-2-9B 71.5 Qwen-2.5-7B 70.4 Yi-1.5-9B 68.4 InternLM-2.5-7B 64.5 Mistral-7B-v0.3 63.9 ChatGLM3-6B 50.4

The model demonstrates:

Outperformance of all 8B parameter models
Comparable performance to GPT-4o (80.4%)
~1000x more cost-effective than proprietary models
7 percentage-point improvement over base Llama-3.1-8b model

Training Data

Continued Pre-training:
    ~250,000 arXiv preprints (2007-2024) from astro-ph and gr-qc
    Astronomy-related Wikipedia articles
    Selected astronomy textbooks
    Total: 3.3 billion tokens, 19.9 GB plaintext

Supervised Fine-tuning:
    8.8 million curated QA pairs
    Filtered Infinity-Instruct-7M dataset
    Paper summaries and metadata
    Total: 2.0 billion tokens, 9.8 GB plaintext

Intended Use

Curiosity-driven question answering
Brainstorming new ideas
Astronomical research assistance
Educational support in astronomy
Literature review and summarization
Scientific explanation of concepts

Limitations

Training data cutoff: January 2024
As with all LLMs, hallucinations are possible
Limited by 8B parameter size for complex reasoning
Paper metadata not perfectly memorized
Performance primarily validated on multiple-choice questions
Primarily trained for use in English

Technical Specifications

Architecture: Based on Meta-Llama 3.1
Training Infrastructure: ORNL OLCF Frontier
Hosting: Hugging Face Hub (AstroMLab/AstroSage-8B)

Ethical Considerations

While this model is designed for scientific use:

Should not be used as sole source for critical research decisions
Output should be verified against primary sources
May reflect biases present in astronomical literature

Use with llama.cpp

Install llama.cpp through brew (works on Mac and Linux)

brew install llama.cpp

Invoke the llama.cpp server or the CLI.

CLI:

llama-cli --hf-repo Triangle104/AstroSage-8B-Q4_K_S-GGUF --hf-file astrosage-8b-q4_k_s.gguf -p "The meaning to life and the universe is"

Server:

llama-server --hf-repo Triangle104/AstroSage-8B-Q4_K_S-GGUF --hf-file astrosage-8b-q4_k_s.gguf -c 2048

Note: You can also use this checkpoint directly through the usage steps listed in the Llama.cpp repo as well.

Step 1: Clone llama.cpp from GitHub.

git clone https://github.com/ggerganov/llama.cpp

Step 2: Move into the llama.cpp folder and build it with LLAMA_CURL=1 flag along with other hardware-specific flags (for ex: LLAMA_CUDA=1 for Nvidia GPUs on Linux).

cd llama.cpp && LLAMA_CURL=1 make

Step 3: Run inference through the main binary.

./llama-cli --hf-repo Triangle104/AstroSage-8B-Q4_K_S-GGUF --hf-file astrosage-8b-q4_k_s.gguf -p "The meaning to life and the universe is"

or

./llama-server --hf-repo Triangle104/AstroSage-8B-Q4_K_S-GGUF --hf-file astrosage-8b-q4_k_s.gguf -c 2048
