## 💰 Cost Breakdown

OpenAI is **very affordable** for survey work:

### Typical Costs with GPT-4o-mini (Recommended):

| Task | Approximate Cost |
|------|------------------|
| Generate 10-question survey | $0.01 - $0.02 |
| Translate to 5 languages | $0.03 - $0.05 |
| Analyze 50 responses | $0.05 - $0.10 |
| **Complete workflow** | **$0.09 - $0.17** |

### With $10 credit, you can:
- Generate ~500 surveys
- Translate ~200 surveys to 5 languages each
- Analyze ~100 datasets with 50 responses each
- Run ~60-100 complete workflows (generate + translate + analyze)

### Cost Control Tips:

1. **Use GPT-4o-mini** (default) - Much cheaper than GPT-4
   ```bash
   LLM_MODEL=gpt-4o-mini  # Already the default
   ```

2. **Set usage limits:**
   - Go to https://platform.openai.com/account/limits
   - Set monthly limit (e.g., $10/month)
   - Get email alerts at 50%, 75%, 90%

## 🔄 Switching from HuggingFace

Already using HuggingFace? Here's how to switch:

### On HuggingFace Spaces:

1. **Add OpenAI credentials** (see Step 3 above)
2. **Restart Space**
3. **That's it!** No code changes needed

The app automatically detects OpenAI credentials and uses them.

### What happens to HuggingFace?

- HuggingFace still works as fallback
- OpenAI takes priority if both are configured
- You can remove HF token if you want

---

## 🧪 Test Your Setup

Run this to verify OpenAI is working:

```bash
python check_env.py
```

Should show:
```
✅ OPENAI_API_KEY     SET (sk-proj-...)
✅ LLM_PROVIDER       SET (openai)
```

And at the bottom:
```
✅ Will use: OpenAI (explicit)
```

Or test directly in the app - look for:
```
✅ Active LLM Provider: OPENAI | Model: gpt-4o-mini
```

---

## 🆘 Troubleshooting

### "Invalid API key"
- Check key starts with `sk-`
- Make sure you copied the full key
- Regenerate if needed: https://platform.openai.com/api-keys

### "Insufficient quota"
- Add credits: https://platform.openai.com/account/billing
- Minimum: $5 recommended

### "Rate limit exceeded"
- You're on free tier - upgrade to pay-as-you-go
- Or wait a few minutes

### Still using HuggingFace?
- Check LLM_PROVIDER is set to "openai"
- Check OPENAI_API_KEY is set correctly
- Run `python check_env.py`

## 💡 Pro Tips

### 1. Use Different Models for Different Tasks

```bash
# For survey generation (fast, cheap)
LLM_MODEL=gpt-4o-mini

# For complex analysis (better quality, more expensive)
LLM_MODEL=gpt-4o
```

### 2. Monitor Costs

Set up email alerts:
- 50% of limit: Review usage
- 75% of limit: Check if expected
- 90% of limit: Urgent review

### 3. Batch Operations

- Generate multiple survey versions at once
- Translate to all languages together
- More efficient than one at a time

### 4. Cache Results

- Save generated surveys
- Reuse translations when possible
- Don't regenerate unnecessarily

## 📊 Monthly Cost Estimates

Based on typical usage:

**Light Use (10 surveys/month):**
- Generate: 10 surveys × $0.02 = $0.20
- Translate: 5 translations × $0.04 = $0.20
- Analyze: 5 analyses × $0.08 = $0.40
- **Total: ~$1/month**

**Medium Use (50 surveys/month):**
- Generate: 50 × $0.02 = $1.00
- Translate: 25 × $0.04 = $1.00
- Analyze: 25 × $0.08 = $2.00
- **Total: ~$4/month**

**Heavy Use (200 surveys/month):**
- Generate: 200 × $0.02 = $4.00
- Translate: 100 × $0.04 = $4.00
- Analyze: 100 × $0.08 = $8.00
- **Total: ~$16/month**

**Enterprise (1000+ surveys/month):**
- Contact OpenAI for volume pricing
- Consider fine-tuned models
- Estimated: $50-100/month
