## When to Use Which Model

### Claude (DEFAULT) - Use for Everything
- All medical/cardiology content
- YouTube scripts (Hinglish)
- Twitter/X content (English)
- Editorials and newsletters
- Anything requiring accuracy

### GLM-4.7 (Z.AI) - Bulk & Comparison
**Cost:** $0.10/M tokens (100x cheaper than Claude)
**Use when:**
- Generating multiple draft variations
- A/B testing content angles
- Bulk social media post generation
- First drafts for quick iteration
- Cost is a primary concern

```
/write-glm "Generate 5 different hooks for a video about statin myths"
```

### GPT-4o / GPT-4o-mini - Quality Alternative
**Cost:** $0.60/M (mini) or $10/M (4o)
**Use when:**
- You want to compare Claude vs GPT style
- Specific OpenAI capabilities needed
- User explicitly requests "GPT style"

```
/write-gpt "Write an editorial on SGLT2 inhibitors" --model=4o-mini
```

### Gemini - Research & Free Tier
**Cost:** FREE (1500 requests/day via AI Studio)
**Use when:**
- Web research integration
- Fact-checking
- You want Google's knowledge
- Budget is zero

```
/write-gemini "Summarize recent GLP-1 agonist research"
```

### Grok (xAI) - Real-time & X/Twitter
**Cost:** $15/M tokens (expensive)
**Use when:**
- Real-time X/Twitter trends
- Content specifically for X platform
- You want Grok's "unfiltered" style

```
/write-grok "What's trending in cardiology on X right now?"
```

## API Configuration

All APIs are configured in `.env`:

```bash
# Check which APIs are configured
cat .env | grep -E "API_KEY|_KEY"
```

### Required Environment Variables

| Variable | Model | Get From |
|----------|-------|----------|
| `ANTHROPIC_API_KEY` | Claude | console.anthropic.com |
| `ZAI_API_KEY` | GLM-4.7 | z.ai |
| `OPENAI_API_KEY` | GPT-4o | platform.openai.com |
| `GOOGLE_API_KEY` | Gemini | aistudio.google.com (FREE) |
| `XAI_API_KEY` | Grok | console.x.ai |

---

## Python Integration

### Direct API Calls

```python
from multi_model_writer import ModelRouter

router = ModelRouter()

# Default (Claude via current session)
response = router.write("Your prompt here")

# Specific model
response = router.write("Your prompt", model="glm-4.7")
response = router.write("Your prompt", model="gpt-4o-mini")
response = router.write("Your prompt", model="gemini")
response = router.write("Your prompt", model="grok")

# Cost-optimized (auto-selects cheapest)
response = router.write("Your prompt", optimize="cost")

# Quality-optimized (auto-selects best for task)
response = router.write("Your prompt", optimize="quality")
```

### Batch Comparison

```python
# Generate same content across multiple models for comparison
results = router.compare(
    prompt="Write a tweet about the EMPEROR-Preserved trial",
    models=["claude", "glm-4.7", "gpt-4o-mini"]
)

for model, output in results.items():
    print(f"\n=== {model} ===")
    print(output)
```

---

## Browser Automation (Web Interfaces)

For using your ChatGPT Plus and Gemini Advanced subscriptions:

### Setup

```bash
# Ensure Playwright is installed
pip install playwright
playwright install chromium
```

### Usage

See `browser-automation` skill for detailed instructions.

```
/browser-chat "Your prompt" --target=chatgpt
/browser-chat "Your prompt" --target=gemini
```

This skill works WITH your existing cardiology skills:

```
1. Use `youtube-script-master` → Routes to Claude by default
2. Use `cardiology-editorial` → Routes to Claude by default
3. Add `--model=glm-4.7` → Overrides to cheaper model
4. Use `/compare` → See all models side-by-side
```
