# Admin Panel - AI Provider Configuration

## Overview

Admins can configure AI providers **directly through the admin panel** without touching code or `.env` files. The system supports three AI providers with automatic failover.

---

## 🎯 Quick Start for Admins

### Step 1: Access Admin Panel

Navigate to the admin configurations page in your workflow system.

### Step 2: Configure AI Provider

Look for the **AI Configuration** section with these settings:

| Setting | Description | Example Value |
|---------|-------------|---------------|
| **AI Provider** | Choose your AI provider | `claude`, `openai`, or `gemini` |
| **Claude API Key** | API key from Anthropic | `sk-ant-xxxxxxxxxxxxx` |
| **OpenAI API Key** | API key from OpenAI | `sk-proj-xxxxxxxxxxxxx` |
| **Gemini API Key** | API key from Google | `AIzaxxxxxxxxxxxxxxx` |
| **Enable AI Features** | Turn AI on/off | `true` or `false` |

### Step 3: Get Your API Key

Choose ONE provider and get an API key:

#### Option A: Claude (Recommended)
1. Go to https://console.anthropic.com
2. Create account / Sign in
3. Generate API key
4. Copy key (starts with `sk-ant-`)

#### Option B: OpenAI
1. Go to https://platform.openai.com
2. Create account / Sign in  
3. Navigate to API keys
4. Create new key
5. Copy key (starts with `sk-proj-` or `sk-`)

#### Option C: Gemini (Free Tier Available!)
1. Go to https://ai.google.dev
2. Sign in with Google account
3. Get API key
4. Copy key

### Step 4: Configure in Admin Panel

**Example: Setting up Claude**

1. Set **AI Provider** = `claude`
2. Set **Claude API Key** = `sk-ant-api03-xxxxxxxxxxxxx`
3. Leave other API keys empty (optional)
4. Set **Enable AI Features** = `true`
5. Click **Save Configuration**

✅ **Done!** The system will automatically initialize Claude.

## 🔄 How It Works

### Automatic Initialization

When you save the configuration:

```
Admin saves config
  ↓
System clears cache
  ↓
AI Service reads new config from database
  ↓
Initializes selected provider (Claude/OpenAI/Gemini)
  ↓
✅ AI features active
```

**You'll see in server logs:**
```
info: [Admin] AI configuration 'AI_PROVIDER' updated
info: [AI Service] Reinitializing AI provider from updated configuration...
info: [AI Service] Preferred provider from config: claude
info: [AI Service] ✅ Claude provider initialized
info: [AI Service] ✅ Active provider: Claude (Anthropic)
info: [Admin] AI service reinitialized with Claude (Anthropic)
```

### Automatic Failover

If your primary provider fails, the system automatically tries alternatives:

```sql
-- Example: Admin configured Claude, but API key is invalid
UPDATE admin_configurations 
SET config_value = 'claude' 
WHERE config_key = 'AI_PROVIDER';

UPDATE admin_configurations 
SET config_value = 'sk-ant-INVALID' 
WHERE config_key = 'CLAUDE_API_KEY';
```

**System Response:**
```
warn: [AI Service] Claude API key not configured.
warn: [AI Service] Preferred provider unavailable. Trying fallbacks...
info: [AI Service] ✅ OpenAI provider initialized
info: [AI Service] ✅ Using fallback provider: OpenAI (GPT-4)
```

✅ **AI features still work!** (if OpenAI key is configured)

## 📋 Configuration Guide by Provider

### Claude (Anthropic) - Best for Production

**Pros:**
- ✅ High-quality, professional output
- ✅ Excellent instruction following
- ✅ Good for formal business documents
- ✅ Reliable and consistent

**Cons:**
- ⚠️ Paid service (no free tier)
- ⚠️ Requires account setup

**Configuration:**
```
AI_PROVIDER = claude
CLAUDE_API_KEY = sk-ant-api03-xxxxxxxxxxxxx
```

**Cost:** ~$0.004 per conclusion generation

---

### OpenAI (GPT-4) - Industry Standard

**Pros:**
- ✅ Fast response times
- ✅ Well-documented
- ✅ Widely used and trusted
- ✅ Good performance

**Cons:**
- ⚠️ Paid service
- ⚠️ Higher cost than alternatives

**Configuration:**
```
AI_PROVIDER = openai
OPENAI_API_KEY = sk-proj-xxxxxxxxxxxxx
```

**Cost:** ~$0.005 per conclusion generation

---

### Gemini (Google) - Cost-Effective

**Pros:**
- ✅ **Free tier available!**
- ✅ Good performance
- ✅ Easy Google integration
- ✅ Generous rate limits

**Cons:**
- ⚠️ Slightly lower quality than Claude/GPT-4
- ⚠️ Rate limits on free tier

**Configuration:**
```
AI_PROVIDER = gemini
GEMINI_API_KEY = AIzaxxxxxxxxxxxxxxx
```

**Cost:** **FREE** (up to rate limits), then $0.0001 per generation

---

## 🔐 Security Best Practices

### 1. API Key Storage
- ✅ **Stored in database** (encrypted in production)
- ✅ **Marked as sensitive** (hidden in UI by default)
- ✅ **Never exposed** to frontend
- ✅ **Admin access only**

### 2. Key Rotation
- Rotate API keys every 3-6 months
- Update in admin panel
- System automatically reinitializes

### 3. Access Control
- Only **Super Admins** can update AI configurations
- Regular users cannot view API keys
- All changes are logged in audit trail

---

## 🧪 Testing AI Configuration

### Method 1: Check Status via API

```bash
curl -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  http://localhost:5000/api/v1/ai/status
```

**Response:**
```json
{
  "success": true,
  "data": {
    "available": true,
    "provider": "Claude (Anthropic)",
    "status": "active"
  }
}
```

### Method 2: Check Server Logs

Look for initialization logs when server starts:

```
info: [AI Service] Preferred provider from config: claude
info: [AI Service] ✅ Claude provider initialized
info: [AI Service] ✅ Active provider: Claude (Anthropic)
```

### Method 3: Test in Application

1. Create a workflow request
2. Complete all approvals
3. As initiator, click "Finalize & Close Request"
4. Click "Generate with AI"
5. Should see AI-generated conclusion

---

## 🔄 Switching Providers

### Example: Switching from Claude to Gemini

**Current Configuration:**
```
AI_PROVIDER = claude
CLAUDE_API_KEY = sk-ant-xxxxxxxxxxxxx
```

**Steps to Switch:**

1. **Get Gemini API key** from https://ai.google.dev
2. **Open Admin Panel** → AI Configuration
3. **Update settings:**
   - Set **AI Provider** = `gemini`
   - Set **Gemini API Key** = `AIzaxxxxxxxxxxxxxxx`
4. **Click Save**

**Result:**
```
info: [Admin] AI configuration 'AI_PROVIDER' updated
info: [AI Service] Reinitializing...
info: [AI Service] Preferred provider from config: gemini
info: [AI Service] ✅ Gemini provider initialized
info: [AI Service] ✅ Active provider: Gemini (Google)
```

✅ **Done!** System now uses Gemini. **No server restart needed!**

---

## 💡 Pro Tips

### 1. Multi-Provider Setup (Recommended)

Configure ALL three providers for maximum reliability:

```
AI_PROVIDER = claude
CLAUDE_API_KEY = sk-ant-xxxxxxxxxxxxx
OPENAI_API_KEY = sk-proj-xxxxxxxxxxxxx
GEMINI_API_KEY = AIzaxxxxxxxxxxxxxxx
AI_ENABLED = true
```

**Benefits:**
- If Claude is down → automatically uses OpenAI
- If OpenAI is down → automatically uses Gemini
- **Zero downtime** for AI features!

### 2. Cost Optimization

**Development/Testing:**
- Use `gemini` (free tier)
- Switch to paid provider only for production

**Production:**
- Use `claude` for best quality
- Or use `openai` for fastest responses

### 3. Monitor Usage

Check which provider is being used:

```sql
SELECT 
  ai_model_used,
  COUNT(*) as usage_count,
  AVG(ai_confidence_score) as avg_confidence
FROM conclusion_remarks
WHERE created_at > NOW() - INTERVAL '30 days'
GROUP BY ai_model_used;
```

---

## ⚠️ Troubleshooting

### Issue: "AI Service not configured"

**Check:**
1. Is `AI_ENABLED` set to `true`?
2. Is at least one API key configured?
3. Is the API key valid?

**Fix:**
- Open Admin Panel
- Verify AI Provider setting
- Re-enter API key
- Click Save

### Issue: "Failed to generate conclusion"

**Check:**
1. API key still valid (not expired/revoked)?
2. Provider service available (check status.anthropic.com, etc.)?
3. Sufficient API quota/credits?

**Fix:**
- Test API key manually (use provider's playground)
- Check account balance/quota
- Try switching to different provider

### Issue: Provider keeps failing

**Fallback Strategy:**
1. Configure multiple providers
2. System will auto-switch
3. Check logs to see which one succeeded
