**Ragmint** (Retrieval-Augmented Generation Model Inspection & Tuning) is a modular, developer-friendly Python library for **evaluating, optimizing, and tuning RAG (Retrieval-Augmented Generation) pipelines**.

It provides a complete toolkit for **retriever selection**, **embedding model tuning**, **automated RAG evaluation**, and **config-driven prebuilding** of pipelines with support for **Optuna-based Bayesian optimization**, **Auto-RAG tuning**, **chunking**, and **explainability** through Gemini or Claude.

---

## ✨ Features

- ✅ **Automated hyperparameter optimization** (Grid, Random, Bayesian via Optuna).
- 🤖 **Auto-RAG Tuner** — dynamically recommends retriever–embedding pairs based on corpus size and document statistics, **suggests multiple chunk sizes with overlaps**, and can **test configurations to identify the best-performing RAG setup**.
- 🧮 **Validation QA Generator** — automatically creates QA datasets from a corpus for evaluating and tuning RAG pipelines when no labeled data is available.
- 🧠 **Explainability Layer** — interprets RAG performance via Gemini or Claude APIs.
- 🏆 **Leaderboard Tracking** — stores and ranks experiment runs via JSON or external DB.
- 🔍 **Built-in RAG evaluation metrics** — faithfulness, recall, BLEU, ROUGE, latency.
- 📦 **Chunking system** — automatic or configurable `chunk_size` and `overlap` for documents with multiple suggested pairs.  
- ⚙️ **Retrievers** — FAISS, Chroma, scikit-learn.  
- 🧩 **Embeddings** — Hugging Face.
- 💾 **Caching, experiment tracking, and reproducibility** out of the box.
- 🧰 **Clean modular structure** for easy integration in research and production setups.
- 🏗️ **Langchain Prebuilder** — prepares pipelines, applies chunking, embeddings, and vector store creation automatically.
- ⚙️ **Config Adapter (LangchainConfigAdapter)** — normalizes configuration, fills defaults, validates retrievers.

---

## 🚀 Quick Start

### Installation

```bash
git clone https://github.com/andyolivers/ragmint.git
cd ragmint
pip install -e .
python -m ragmint.app
```

> The `-e` flag installs Ragmint in editable (development) mode.  
> Requires **Python ≥ 3.9**.

### Installation via PyPI

```bash
pip install ragmint
```

---

### 2️⃣ Run a RAG Optimization Experiment

```bash
python ragmint/main.py --config configs/default.yaml --search bayesian
```

Example `configs/default.yaml`:
```yaml
retriever: faiss
embedding_model: text-embedding-3-small
chunk_size: 500
overlap: 100
reranker:
  mode: mmr
  lambda_param: 0.5
optimization:
  search_method: bayesian
  n_trials: 20
```

---

### 3️⃣ Manual Pipeline Usage

```python
from ragmint.prebuilder import PreBuilder
from ragmint.tuner import RAGMint

# Prebuild pipeline (chunking, embeddings, vector store)
prebuilder = PreBuilder(
    docs_path="data/docs/",
    config_path="configs/default.yaml"
)
pipeline = prebuilder.build_pipeline()

# Initialize RAGMint with prebuilt components
rag = RAGMint(pipeline=pipeline)

# Run optimization
best, results = rag.optimize(validation_set=None, metric="faithfulness", trials=3)
print("Best configuration:", best)

```
---
# 🧩 Embeddings and Retrievers

**Ragmint** supports a flexible set of embeddings and retrievers, allowing you to adapt easily to various **RAG architectures**.

---
## 🧩 Chunking System

* **Automatically splits documents** into chunks with `chunk_size` and `overlap` parameters.
* **Supports default values** if not provided in configuration.
* **Optimized** for downstream **retrieval and embeddings**.
* **Enables adaptive chunking strategies** in future releases.
---
## 🧮 Validation QA Generator

The **QA Generator** module automatically creates **question–answer (QA) validation datasets** from any corpus of `.txt` documents.  
This dataset can be used to **evaluate and tune RAG pipelines** inside Ragmint when no labeled data is available.

### ✨ Key Capabilities

- 🔁 **Batch processing** — splits large corpora into batches to prevent token overflows and API timeouts.

- 🧠 **Topic-aware question estimation** — dynamically determines how many questions to generate per document based on:
  - Document length (logarithmic scaling)
  - Topic diversity (via `SentenceTransformer` + `KMeans` clustering)

- 🤖 **LLM-powered QA synthesis** — generates factual QA pairs using **Gemini** or **Claude** models.

- 💾 **Automatic JSON export** — saves the generated dataset to `experiments/validation_qa.json` (configurable).

### ⚙️ Usage

You can run the generator directly from the command line:

```bash
python -m ragmint.qa_generator --density 0.005
```

### 💡 Example: Using in Python

```python
from ragmint.qa_generator import generate_validation_qa

generate_validation_qa(
    docs_path="data/docs",                          # Folder with .txt documents
    output_path="experiments/validation_qa.json",   # Output JSON file
    llm_model="gemini-2.5-flash-lite",              # or "claude-3-opus-20240229"
    batch_size=5,                                   # Number of docs per LLM call
    sleep_between_batches=2,                        # Wait time between calls (seconds)
    min_q=3,                                        # Minimum questions per doc
    max_q=25                                        # Maximum questions per doc
)
```
✅ The generator supports both Gemini and Claude models.  
Set your API key in a `.env` file or via environment variables:
```
export GOOGLE_API_KEY="your_gemini_key"
export ANTHROPIC_API_KEY="your_claude_key"
```

---
## 🧩 Langchain Config Adapter

* **Ensures consistent configuration** across pipeline components.
* **Normalizes retriever and embedding names** (e.g., `faiss`, `sentence-transformers/...`).
* **Adds default chunk parameters** when missing.
* **Validates retriever backends** and **raises clear errors** for unsupported options.

---
## 🧩 Langchain Prebuilder

**Automates pipeline preparation:**
1. Reads documents
2. Applies chunking
3. Creates embeddings
4. Initializes retriever / vector store
5. Returns ready-to-use pipeline** for RAGMint or custom usage.

---

## 🔤 Available Embeddings (Hugging Face)

You can select from the following models:

* `sentence-transformers/all-MiniLM-L6-v2` — **lightweight**, general-purpose
* `sentence-transformers/all-mpnet-base-v2` — **higher accuracy**, slower
* `BAAI/bge-base-en-v1.5` — **multilingual**, dense embeddings
* `intfloat/multilingual-e5-base` — ideal for **multilingual corpora**



### Configuration Example

Use the following format in your config file to specify the embedding model:

```yaml
embedding_model: sentence-transformers/all-MiniLM-L6-v2
```
---

## 🔍 Available Retrievers

**Ragmint** integrates multiple **retrieval backends** to suit different needs:

| Retriever | Description |
| :--- | :--- |
| **FAISS** | Fast vector similarity search; efficient for dense embeddings |
| **Chroma** | Persistent vector DB; works well for incremental updates |
| **scikit-learn (NearestNeighbors)** | Lightweight, zero-dependency local retriever |


### Configuration Example

To specify the retriever in your configuration file, use the following format:

```yaml
retriever: faiss
```

---

## 🧪 Dataset Options

Ragmint can automatically load evaluation datasets for your RAG pipeline:

| Mode | Example | Description |
|------|----------|-------------|
| 🧱 **Default** | `validation_set=None` | Uses built-in `experiments/validation_qa.json` |
| 📁 **Custom File** | `validation_set="data/my_eval.json"` | Load your own QA dataset (JSON or CSV) |
| 🌐 **Hugging Face Dataset** | `validation_set="squad"` | Automatically downloads benchmark datasets (requires `pip install datasets`) |

### Example

```python
from ragmint.tuner import RAGMint

ragmint = RAGMint(
    docs_path="data/docs/",
    retrievers=["faiss", "chroma"],
    embeddings=["text-embedding-3-small"],
    rerankers=["mmr"],
)

# Use built-in default
ragmint.optimize(validation_set=None)

# Use Hugging Face benchmark
ragmint.optimize(validation_set="squad")

# Use your own dataset
ragmint.optimize(validation_set="data/custom_qa.json")
```

---

## 🧠 Auto-RAG Tuner

The **AutoRAGTuner** automatically analyzes your corpus and recommends retriever–embedding combinations based on corpus statistics (size and average document length). It also **suggests multiple chunk sizes with overlaps** to improve retrieval performance.

Beyond recommendations, it can **run full end-to-end testing** of the suggested configurations and **identify the best-performing RAG setup** for your dataset.


```python
from ragmint.autotuner import AutoRAGTuner

# Initialize with your documents
tuner = AutoRAGTuner(docs_path="data/docs/")

# Recommend configurations and suggest chunk sizes
recommendation = tuner.recommend(num_chunk_pairs=5)
print("Initial recommendation:", recommendation)

# Run full auto-tuning on validation set
best_config, results = tuner.auto_tune(validation_set="data/validation.json", trials=5)
print("Best configuration after testing:", best_config)
print("All trial results:", results)
```
---

---

## 🏆 Leaderboard Tracking

Track and visualize your best experiments across runs.

```python
from ragmint.leaderboard import Leaderboard

# Initialize local leaderboard
leaderboard = Leaderboard(storage_path="leaderboard.jsonl")

# Retrieve top 5 runs
print("\n🏅 Top 5 Experiments:")
for result in leaderboard.top_results(limit=5):
    print(f"{result['run_id']} | Score: {result['best_score']:.2f} | Model: {result['model']}")
```

---

## 🧠 Explainability with Gemini / Claude

Compare RAG configurations and receive **natural language insights** on why one performs better.

```python
from ragmint.autotuner import AutoRAGTuner
from ragmint.explainer import explain_results

tuner = AutoRAGTuner(docs_path="data/docs/")
best, results = tuner.auto_tune(
    validation_set='data/docs/validation_qa.json',
    metric="faithfulness",
    trials=5,
    search_type='bayesian'
)

analysis = explain_results(best, results, corpus_stats=tuner.corpus_stats)
print(analysis)
```

> Set your API keys in a `.env` file or via environment variables:
> ```
> export GEMINI_API_KEY="your_gemini_key"
> export ANTHROPIC_API_KEY="your_claude_key"
> ```
