4. Click Generate New Key
5. Copy your API key

Your API key looks like: csk-... (starts with csk-)

Step 2: Configure Locally

Option A: Using .env file (for local development)

# Edit .env file
cd "/Users/niro/Documents/SL Clinical Assistant"
nano .env

Replace <YOUR_CEREBRAS_API_KEY_HERE> with your actual key:

CEREBRAS_API_KEY=csk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Option B: Export environment variable

export CEREBRAS_API_KEY=csk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Step 3: Install Dependencies

# Install Cerebras SDK
pip install cerebras-cloud-sdk

# Or install all requirements
pip install -r requirements.txt

---

🧪 Testing

Test Locally

cd "/Users/niro/Documents/SL Clinical Assistant"

# Set your API key
export CEREBRAS_API_KEY=csk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxx

# Run the application
python app.py

Then open: http://localhost:7860

Test Query

Try asking:

What is the management protocol for severe preeclampsia?

You should see:

• ✅ Ultra-fast response (< 3 seconds)
• ✅ Medical citations included
• ✅ Verification status displayed

---

🚀 Deploy to Hugging Face Spaces

Step 1: Configure Secrets

1. Go to your Hugging Face Space
2. Click Settings tab
3. Navigate to Repository secrets
4. Click Add a secret

Add:

• Name: CEREBRAS_API_KEY
• Value: csk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxx (your key)

Step 2: Push Changes

cd "/Users/niro/Documents/SL Clinical Assistant"

git add .
git commit -m "feat: Migrate to Cerebras Inference for ultra-fast responses"
git push origin main

Step 3: Verify Deployment

1. Watch build logs in HF Spaces
2. Look for: ✅ Cerebras API connection successful
3. Test with a query
4. Check response time (should be < 3 seconds!)

🔧 Technical Details

API Compatibility

Cerebras uses an OpenAI-compatible API, so the migration was straightforward:

# Before (Groq)
from groq import Groq
client = Groq(api_key=api_key)

# After (Cerebras)
from cerebras.cloud.sdk import Cerebras
client = Cerebras(api_key=api_key)

Same method calls:

response = client.chat.completions.create(
    model="llama-3.3-70b",
    messages=[{"role": "user", "content": "..."}]
)

Model Specifications

Llama 3.3 70B on Cerebras:

• Parameters: 70 billion
• Context: 8,192 tokens
• Speed: 2000+ tokens/second
• Optimization: Cerebras CS-3 hardware
• Specialization: Medical, coding, reasoning
