## Introduction: Hippo — A One-Stop Local LLM Inference and RAG Solution for Consumer Hardware

Hippo is a Python toolkit that integrates local LLM inference and document retrieval. It supports pipeline parallelism to split models across multiple devices, has built-in BM25 + semantic hybrid search, requires no additional vector databases, can be installed via `pip install hippo-llm`, and enables running 30B models on consumer hardware.

## Background: Pain Points of Traditional Local LLM and RAG Deployment

Running LLMs locally and implementing RAG traditionally requires deploying multiple independent services (e.g., Ollama for inference, ChromaDB/Pinecone for vector storage). This fragmentation increases deployment complexity and maintenance costs.

## Core Capability: Pipeline Parallel Inference

Hippo uses a lightweight pipeline parallelism approach:
- Pure TCP communication, no MPI environment required
- Cross-platform support (mixed Mac/PC networking)
- Automatic sharding (calculates layer splitting strategy based on VRAM)
Test data: Two Mac Mini M2 (16GB each) running Qwen3-30B-A3B-Q3 achieve 78 tokens/sec, while a single machine only reaches 24 tokens/sec—speedup is close to linear scaling.

## Built-in Hybrid Search: No More External Vector Databases

Hippo's `VectorStore` is implemented based on SQLite and supports:
- Dense retrieval (Nomic Embed semantic similarity)
- Sparse retrieval (BM25 keyword matching with optimized Chinese word segmentation)
- Hybrid fusion (RRF algorithm to merge results)
Runs completely offline with millisecond-level query latency and no additional service processes needed.

## Practical Use Cases

1. **Personal Knowledge Base Q&A**: Import papers/notes, use natural language queries to locate content, generate answers with local models—data never leaves your device;
2. **Internal Document Assistant for Small/Medium Teams**: Deploy on intranets to provide intelligent Q&A for industries like finance/healthcare that can't use cloud models;
3. **Model Capability Exploration**: Experience 30B models on consumer hardware to evaluate the value of fine-tuning/production deployment.

## Highlights of Technical Architecture

- **OpenAI-compatible API**: Exposes the `/v1/chat/completions` endpoint for seamless integration with LangChain and LlamaIndex;
- **Loop Detection**: Semantic loop detection based on Jaccard similarity, complementing traditional repetition penalties;
- **Chinese Optimization**: Built-in Chinese BM25 tokenizer and stopword list—no external libraries needed for Chinese retrieval.

## Performance Benchmark Data

| Configuration | Model | Speed |
|------|------|------|
| Mac Mini M2 (16GB) | Qwen3-4B-Q4 | 41 tok/s |
| RTX 5060 Ti (16GB) | Qwen3-14B-Q4 | 41 tok/s |
| 2× Mac Mini (16GB each) | Qwen3-30B-A3B-Q3 |78 tok/s |
| Mac Mini M2 (16GB) | Qwen3-30B-A3B-Q3 |24 tok/s |
The multi-machine collaboration mode provides an alternative for users with limited budgets to access large model capabilities.

## Project Status and Roadmap

Current version is v0.3, supporting ANN indexing (suitable for collections of over 10,000 documents); the roadmap will include features like multi-sharding (over 2 devices), automatic layer balancing, and cross-shard speculative decoding.
The project is open-source under the MIT license, depends on Python 3.10+ and a local Ollama service to obtain model weights, and is a practical solution to simplify local LLM deployment.
