+# Deployment Guide for Hugging Face Spaces
+
+## Problem Solved
+
+**Issue**: Hugging Face Spaces rejects files larger than 10 MiB without Git LFS.
+
+**Previous setup**: 
+- ❌ Committed 94 MB of vector database files to git
+- ❌ Committed 12 MB of MMLU results JSON
+
+**New setup**:
+- ✅ Build vector database on first app launch
+- ✅ Only commit code files (~50 KB)
+- ✅ Database builds in ~3-5 minutes on first launch
+
+## How It Works
+
+1. **First Launch**: App detects empty database and builds it from HuggingFace datasets
+2. **Subsequent Launches**: App loads existing database from Hugging Face persistent storage
+
+## Files Excluded from Git
+
+Added to `.gitignore`:
+```
+data/benchmark_vector_db/          # ChromaDB vector database (builds automatically)
+data/benchmark_results/mmlu_real_results.json  # Large benchmark file (not needed)
+```
+
+## Deployment Steps
+
+### 1. Clean Git History (Remove Large Files)
+
+```bash
+cd Togmal-demo
+
+# Remove large files from git tracking
+git rm -r --cached data/benchmark_vector_db/
+git rm --cached data/benchmark_results/mmlu_real_results.json
+
+# Commit the removal
+git add .gitignore app.py
+git commit -m "Remove large files - build database on startup instead"
+```
+
+### 2. Clean Git History (Optional - for smaller repo)
+
+If files were already committed to history:
+
+```bash
+# Install git-filter-repo if needed
+brew install git-filter-repo  # macOS
+# or: pip install git-filter-repo
+
+# Remove files from entire history
+git filter-repo --path data/benchmark_vector_db --invert-paths
+git filter-repo --path data/benchmark_results/mmlu_real_results.json --invert-paths
+
+# Force push (be careful!)
+git push origin main --force
+```
+
+### 3. Push to Hugging Face
+
+```bash
+# Push to Hugging Face Spaces
+git remote add hf https://huggingface.co/spaces/JustTheStatsHuman/Togmal-demo
+git push hf main
+```
+
+## First Launch Behavior
+
+When deployed to Hugging Face Spaces:
+
+1. ⏱️ App starts - database is empty
+2. 📥 Downloads benchmark datasets from HuggingFace:
+   - GPQA Diamond (~200 questions)
+   - MMLU-Pro (1000 questions sampled)
+   - MATH (500 questions sampled)
+3. 🧠 Generates embeddings using `all-MiniLM-L6-v2`
+4. 💾 Stores in ChromaDB (persistent across restarts)
+5. ✅ Ready to use!
+
+**Time**: 3-5 minutes on Hugging Face hardware
+
+## Persistent Storage
+
+Hugging Face Spaces provides persistent storage for:
+- `/data` directory (survives app restarts)
+- Our database is stored in `./data/benchmark_vector_db/`
+
+## Why This is Better
+
+| Metric | Before | After |
+|--------|--------|-------|
+| Git repo size | ~100 MB | ~50 KB |
+| Files in git | 94 MB binaries | Code only |
+| First launch | Instant | 3-5 min build |
+| Subsequent | Instant | Instant |
+| Maintainability | Hard to update DB | Rebuild anytime |
+
+## Updating the Database
+
+To rebuild with new data:
+
+```python
+# In app.py, add force rebuild option:
+FORCE_REBUILD = os.getenv("FORCE_REBUILD", "false").lower() == "true"
+
+if db.collection.count() == 0 or FORCE_REBUILD:
+    db.build_database(...)
+```
+
+Then set environment variable in Hugging Face Space settings:
+```
+FORCE_REBUILD=true
+```
+
+## Troubleshooting
+
+### "Database build failed"
+- Check HuggingFace dataset access (may need authentication)
+- Check space has enough memory (upgrade to larger instance)
+
+### "Out of memory during build"
+- Reduce `max_samples_per_dataset` in `app.py`
+- Use smaller embedding model (e.g., `all-MiniLM-L6-v2`)
+
+### "Database not persisting"
+- Ensure database path is `./data/` (Hugging Face persistent dir)
+- Check space hasn't been reset
+
+## Local Development
+
+For local testing:
+
+```bash
+# Install dependencies
+pip install -r requirements.txt
+
+# Run app (builds database on first launch)
+python app.py
+```
+
+Database will be built once, then reused on subsequent runs.

+# Fix for Hugging Face Push Rejection
+
+## The Problem
+
+```
+remote: Your push was rejected because it contains files larger than 10 MiB.
+remote: Offending files:
+remote:   - data/benchmark_results/mmlu_real_results.json (12 MB)
+remote:   - data/benchmark_vector_db/chroma.sqlite3 (58 MB)
+remote:   - data/benchmark_vector_db/.../data_level0.bin (large)
+```
+
+**Total size of offending files:** ~94 MB
+
+## Why It Worked Locally with Gradio but Not on Hugging Face
+
+### Gradio Locally ✅
+- Reads from your local file system
+- No file size limits
+- Database already built and ready
+
+### Hugging Face Spaces ❌
+- **10 MiB file size limit** without Git LFS
+- Checks entire git history (not just current commit)
+- Rejects push if any commit ever had large files
+
+## What the App Actually Needs
+
+Looking at `app.py`, the demo only needs:
+
+1. **Code files** (~50 KB):
+   - `app.py` - Gradio interface
+   - `benchmark_vector_db.py` - Vector DB logic
+   - `requirements.txt` - Dependencies
+
+2. **Small data files** (< 1 MB):
+   - `data/benchmark_results/collection_statistics.json` (540 B)
+   - `data/benchmark_results/raw_benchmark_results.json` (548 KB)
+   - `data/benchmark_results/real_benchmark_data.json` (108 B)
+
+3. **NOT NEEDED in git**:
+   - ❌ `data/benchmark_vector_db/` (81 MB) - Built on first launch
+   - ❌ `data/benchmark_results/mmlu_real_results.json` (12 MB) - Not used by app
+
+## The Solution: Build Database on Startup
+
+### What I Changed
+
+#### 1. **Updated `app.py`** 
+Added auto-build logic:
+
+```python
+# Build database if not exists (first launch on Hugging Face)
+if db.collection.count() == 0:
+    logger.info("Database is empty - building from scratch...")
+    logger.info("This will take 3-5 minutes on first launch.")
+    db.build_database(
+        load_gpqa=True,
+        load_mmlu_pro=True,
+        load_math=True,
+        max_samples_per_dataset=1000
+    )
+    logger.info("✓ Database build complete!")
+```
+
+#### 2. **Created `.gitignore`**
+Excludes large files:
+
+```
+data/benchmark_vector_db/
+data/benchmark_results/mmlu_real_results.json
+```
+
+#### 3. **Removed files from git tracking**
+```bash
+git rm -r --cached data/benchmark_vector_db/
+git rm --cached data/benchmark_results/mmlu_real_results.json
+```
+
+**BUT** - Files are still in git history! That's why push still fails.
+
+## How to Fix
+
+You have **2 options**:
+
+### Option 1: Fresh Start (Recommended - Simplest)
+
+Creates a brand new repository with no history:
+
+```bash
+cd Togmal-demo
+
+# Run the fresh repo script
+./fresh_repo.sh
+
+# Add Hugging Face remote
+git remote add origin https://huggingface.co/spaces/JustTheStatsHuman/Togmal-demo
+
+# Force push (safe since it's a fresh repo)
+git push origin main --force
+```
+
+**Pros:**
+- ✅ Simplest solution
+- ✅ Cleanest repository
+- ✅ No dependencies needed
+
+**Cons:**
+- ❌ Loses git history (probably fine for a demo)
+
+### Option 2: Clean History (Preserves History)
+
+Removes large files from all commits:
+
+```bash
+# Install git-filter-repo
+brew install git-filter-repo  # macOS
+# or: pip install git-filter-repo
+
+# Run the cleaning script
+./clean_git_history.sh
+
+# Re-add remote (filter-repo removes it)
+git remote add origin https://huggingface.co/spaces/JustTheStatsHuman/Togmal-demo
+
+# Force push
+git push origin main --force
+```
+
+**Pros:**
+- ✅ Keeps commit history
+- ✅ More "proper" solution
+
+**Cons:**
+- ❌ Requires additional tool
+- ❌ More complex
+
+## What Happens on First Launch
+
+When deployed to Hugging Face Spaces:
+
+1. **App starts** (database is empty)
+2. **Auto-build begins** (~3-5 minutes):
+   - Downloads GPQA Diamond from HuggingFace
+   - Downloads MMLU-Pro samples
+   - Downloads MATH samples
+   - Generates embeddings with `all-MiniLM-L6-v2`
+   - Stores in ChromaDB
+3. **Database persists** in Hugging Face persistent storage (`/data`)
+4. **Subsequent launches** are instant (database already exists)
+
+## Size Comparison
+
+| What | Before | After |
+|------|--------|-------|
+| Git repo size | ~100 MB | ~1 MB |
+| Files in git | Code + 94 MB binaries | Code only |
+| First launch time | Instant | 3-5 min |
+| Subsequent launches | Instant | Instant |
+| Deployment | ❌ Fails | ✅ Works |
+
+## Why This is Actually Better
+
+1. **Smaller repo** - Faster clones, cleaner history
+2. **Always up-to-date** - Can rebuild with latest data anytime
+3. **More flexible** - Easy to add new datasets
+4. **Follows best practices** - Don't commit generated files
+5. **Works on HF** - No LFS needed
+
+## Testing Locally Before Push
+
+```bash
+cd Togmal-demo
+
+# Ensure large files are ignored
+cat .gitignore
+
+# Remove local vector DB to test auto-build
+rm -rf data/benchmark_vector_db/
+
+# Run app (should build database)
+python app.py
+```
+
+You should see:
+```
+INFO:__main__:Database is empty - building from scratch...
+INFO:__main__:This will take 3-5 minutes on first launch.
+INFO:benchmark_vector_db:Loading GPQA Diamond dataset...
+...
+INFO:__main__:✓ Database build complete!
+```
+
+## Deployment Checklist
+
+- [x] Created `.gitignore` for large files
+- [x] Updated `app.py` with auto-build logic
+- [x] Removed large files from git tracking
+- [ ] **Next: Choose Option 1 or 2 above**
+- [ ] **Then: Push to Hugging Face**
+
+## If It Still Fails
+
+Check file sizes being pushed:
+
+```bash
+# See what files git tracks
+git ls-files | xargs ls -lh
+
+# Check for files > 10 MB
+git ls-files | xargs ls -l | awk '$5 > 10485760'
+```
+

+
+## 🎯 How It Works
+
+### 1️⃣ **First Launch** (~3-5 minutes)
+
+```python
+# app.py automatically detects empty database
+if db.collection.count() == 0:
+    # Downloads datasets from HuggingFace
+    db.build_database(
+        load_gpqa=True,        # 200 expert questions
+        load_mmlu_pro=True,    # 1000 multitask questions  
+        load_math=True,        # 500 competition math
+        max_samples_per_dataset=1000
+    )
+```
+
+**What happens:**
+1. 📥 Downloads GPQA Diamond dataset from HuggingFace
+2. 📥 Downloads MMLU-Pro samples
+3. 📥 Downloads MATH competition problems
+4. 🧠 Generates embeddings using `all-MiniLM-L6-v2`
+5. 💾 Stores in ChromaDB persistent storage
+6. ✅ Ready to use!
+
+### 2️⃣ **Subsequent Launches** (instant)
+
+Database persists in Hugging Face's `/data` directory → loads instantly
+
+---
+
+## 🔍 Why This is Better
+
+| Aspect | Old Way | New Way |
+|--------|---------|---------|
+| **Git Repo Size** | 100 MB | 1 MB |
+| **Deployment** | ❌ Fails | ✅ Works |
+| **First Launch** | Instant | 3-5 min build |
+| **Updates** | Manual rebuild | Auto-rebuild |
+| **Best Practice** | ❌ Commits binaries | ✅ Generates on demand |
+| **Flexibility** | Hard to change | Easy to update datasets |
+
+---
+
+## 📝 Files Created
+
+### `.gitignore`
+Excludes large files from git:
+```gitignore
+data/benchmark_vector_db/
+data/benchmark_results/mmlu_real_results.json
+```
+
+### Updated `app.py`
+Auto-builds database on first launch:
+```python
+# Build database if not exists (first launch on Hugging Face)
+if db.collection.count() == 0:
+    logger.info("Database is empty - building from scratch...")
+    db.build_database(...)
+```
+
+### Helper Scripts
+- `fresh_repo.sh` - Creates fresh git repo (recommended)
+- `clean_git_history.sh` - Cleans history while preserving commits (advanced)
+- `deploy_helper.sh` - Interactive guide
+
+---
+
+## 🎬 Complete Deployment Flow
+
+```bash
+# 1. Navigate to demo folder
+cd /Users/hetalksinmaths/togmal/Togmal-demo
+
+# 2. Create fresh repository (removes large files from history)
+./fresh_repo.sh
+
+# 3. Add Hugging Face remote
+git remote add origin https://huggingface.co/spaces/JustTheStatsHuman/Togmal-demo
+
+# 4. Push to Hugging Face
+git push origin main --force
+
+# 5. Watch it deploy
+# Visit: https://huggingface.co/spaces/JustTheStatsHuman/Togmal-demo
+```
+
+---
+
+## 🐛 Troubleshooting
+
+### "Push still rejected"
+
+Check if large files are still tracked:
+```bash
+# See all files git tracks
+git ls-files | xargs ls -lh
+
+# Find files > 10 MB
+git ls-files | xargs ls -l | awk '$5 > 10485760 {print $9, "(" $5/1048576 " MB)"}'
+```
+
+### "Database build failed on Hugging Face"
+
+Check logs on Hugging Face Space → "Logs" tab
+
+Common issues:
+- **Out of memory**: Reduce `max_samples_per_dataset` in `app.py`
+- **Dataset access denied**: Some datasets require authentication
+- **Timeout**: Increase timeout in Space settings
+
+### "App crashes after database builds"
+
+The database might be too large for the free tier. Solutions:
+1. Reduce samples: `max_samples_per_dataset=500`
+2. Use smaller embedding model
+3. Upgrade to Hugging Face Pro Space
+
+---
+
+## 💡 For Your VC Pitch
+
+**Technical Story to Tell:**

+Benchmark Vector Database for Difficulty-Based Prompt Analysis
+===============================================================
+
+Uses vector similarity search to assess prompt difficulty by finding
+the nearest benchmark questions and computing weighted difficulty scores.
+
+This replaces static clustering with real-time, explainable similarity matching.
+
+Key Innovation:
+- Embed all benchmark questions (GPQA, MMLU-Pro, MATH, etc.) with success rates
+- For any incoming prompt, find K nearest questions via cosine similarity
+- Return weighted difficulty score based on similar questions' success rates
