🚀 HermesLLM

Production-Ready LLM System with Advanced RAG, Training, and Deployment

FeaturesInstallationQuick StartStructureDocumentation


📖 About

HermesLLM is a production-grade LLM platform that enables end-to-end machine learning workflows from data collection to model deployment. The system ingests knowledge from multiple sources (GitHub, Medium, LinkedIn, YouTube), processes it through advanced pipelines, generates training datasets using AI, fine-tunes models with state-of-the-art techniques (LoRA, DPO), and deploys them to AWS SageMaker with comprehensive monitoring.

🎯 Key Capabilities

  • Multi-Source Data Collection: Automated ingestion from LinkedIn, Medium, GitHub, YouTube, and custom sources
  • Intelligent Processing: Advanced text cleaning, chunking (recursive, token-aware, hybrid), and embedding generation
  • Production RAG System: Query expansion, self-query extraction, reranking, and hybrid retrieval
  • AI-Powered Datasets: Automated generation of instruction and preference datasets using OpenAI
  • Advanced Training: LoRA, QLoRA, DPO, ORPO fine-tuning with 4-bit quantization and Unsloth optimization
  • AWS SageMaker Integration: Complete training, deployment, auto-scaling, and endpoint management
  • FastAPI Service: Production-ready REST API with async endpoints
  • Comprehensive Monitoring: Experiment tracking (Comet ML), LLM monitoring (Opik), and custom metrics
  • ZenML Orchestration: Reproducible ML pipelines with artifact tracking and lineage
  • Infrastructure as Code: AWS role management, endpoint deployment, auto-scaling policies
  • Testing Framework: Comprehensive pytest suite with 100+ tests, fixtures, and mocks
  • Data Management: Export/import tools, backup/restore, format migration (JSON/CSV/Parquet)

    user_id="user123",
    full_name="John Doe",
    links=[
        "https://medium.com/@user/article",
        "https://github.com/user/repo",
        "https://www.youtube.com/watch?v=VIDEO_ID"
    ]
)

print(f"Collected: {stats['success']}/{stats['total']}")

2. Process and Embed Documents

# Process all documents
hermes process --chunk-size 500

# Process with filters
hermes process --author-id user123 --limit 100

Python API:

from hermes.pipelines.processing import processing_pipeline

# Run processing pipeline
stats = processing_pipeline(
    author_id="user123",
    chunk_size=500,
    embedding_model="sentence-transformers/all-MiniLM-L6-v2"
)

print(f"Processed {stats['total']} documents")
print(f"Stored {stats['stored']} vectors")

3. Generate Training Datasets

Using Python:

from hermes.datasets import InstructDatasetGenerator
from hermes.core.documents import CleanedDocument

# Load your documents
documents = CleanedDocument.bulk_find(limit=50)

# Generate instruction dataset
generator = InstructDatasetGenerator(
    model="gpt-4",
    num_samples=100
)

dataset = generator.generate_dataset(documents)

# Save to Hugging Face
dataset.push_to_hub("username/my-instruction-dataset")

Using ZenML Pipeline:

from hermes.zenml_pipelines.dataset_generation import dataset_generation_pipeline

# Generate datasets
dataset_generation_pipeline(
    dataset_name="my-instruction-dataset",
