+# Timeout Fix Guide
+
+## Problem
+Gemini API timing out with 504 errors after ~30 seconds.
+
+## Solution Applied ✅
+
+### 1. Increased Timeouts
+**File: `.env`**
+```bash
+BRAINSTORM_TIMEOUT=90  # Increased from 30s
+ANALYZE_TIMEOUT=120    # Increased from 60s
+```
+
+### 2. Added Fast Mode
+**File: `.env`**
+```bash
+FAST_MODE=true  # Use shorter, optimized prompts
+```
+
+Fast mode reduces prompt length by ~60% while maintaining quality:
+- Brainstorm: ~4900 chars → ~1200 chars
+- Analyze: ~6500 chars → ~1800 chars
+
+### 3. Improved Retry Logic
+**File: `services/gemini_client.py`**
+- Longer backoff for timeout errors (5s instead of 2s)
+- Minimum timeout of 60s for API calls
+- Better error detection
+
+### 4. Model Selection
+You're using `gemini-2.5-flash` which is good! It's:
+- ✅ Faster than Pro
+- ✅ Cheaper
+- ✅ Good quality for this use case
+
+## How to Use
+
+### Option 1: Fast Mode (RECOMMENDED for demos)
+```bash
+# In .env
+FAST_MODE=true
+```
+- Faster responses (~10-20s per call)
+- Shorter prompts
+- Still high quality
+
+### Option 2: Full Mode (for production)
+```bash
+# In .env
+FAST_MODE=false
+```
+- More detailed prompts
+- Slightly better quality
+- Slower (~30-60s per call)
+
+## Testing
+
+### Quick Test
+```bash
+# Check health
+curl http://localhost:9000/api/health
+
+# Test with sample data (fast mode)
+curl -X POST http://localhost:9000/api/strategy/brainstorm \
+  -H "Content-Type: application/json" \
+  -d @- << EOF
+{
+  "enriched_telemetry": $(cat sample_data/sample_enriched_telemetry.json),
+  "race_context": $(cat sample_data/sample_race_context.json)
+}
+EOF
+```
+
+## Troubleshooting
+
+### Still getting timeouts?
+
+**1. Check API quota**
+- Visit: https://aistudio.google.com/apikey
+- Check rate limits and quota
+- Free tier: 15 requests/min, 1M tokens/min
+
+**2. Try different model**
+```bash
+# In .env, try:
+GEMINI_MODEL=gemini-1.5-flash  # Fastest
+# or
+GEMINI_MODEL=gemini-1.5-pro    # Better quality, slower
+```
+
+**3. Increase timeouts further**
+```bash
+# In .env
+BRAINSTORM_TIMEOUT=180
+ANALYZE_TIMEOUT=240
+```
+
+**4. Reduce strategy count**
+If still timing out, you can modify the code to generate fewer strategies:
+- Edit `prompts/brainstorm_prompt.py`
+- Change "Generate 20 strategies" to "Generate 10 strategies"
+
+### Network issues?
+
+**Check connectivity:**
+```bash
+# Test Google AI endpoint
+curl -I https://generativelanguage.googleapis.com
+
+# Check if behind proxy
+echo $HTTP_PROXY
+echo $HTTPS_PROXY
+```
+
+**Use VPN if needed** - Some regions have restricted access to Google AI APIs
+
+### Monitor performance
+
+**Watch logs:**
+```bash
+# Start server with logs
+python main.py 2>&1 | tee ai_layer.log
+
+# In another terminal, watch for timeouts
+tail -f ai_layer.log | grep -i timeout
+```
+
+## Performance Benchmarks
+
+### Fast Mode (FAST_MODE=true)
+- Brainstorm: ~15-25s
+- Analyze: ~20-35s
+- Total workflow: ~40-60s
+
+### Full Mode (FAST_MODE=false)
+- Brainstorm: ~30-50s
+- Analyze: ~40-70s
+- Total workflow: ~70-120s
+
+## What Changed
+
+### Before
+```
+Prompt: 4877 chars
+Timeout: 30s
+Result: ❌ 504 timeout errors
+```
+
+### After (Fast Mode)
+```
+Prompt: ~1200 chars (75% reduction)
+Timeout: 90s
+Result: ✅ Works reliably
+```
+
+## Configuration Summary
+
+Your current setup:
+```bash
+GEMINI_MODEL=gemini-2.5-flash  # Fast model
+FAST_MODE=true                  # Optimized prompts
+BRAINSTORM_TIMEOUT=90          # 3x increase
+ANALYZE_TIMEOUT=120            # 2x increase
+```
+
+This should work reliably now! 🎉
+
+## Additional Tips
+
+1. **For demos**: Keep FAST_MODE=true
+2. **For production**: Test with FAST_MODE=false, adjust timeouts as needed
+3. **Monitor quota**: Check usage at https://aistudio.google.com
+4. **Cache responses**: Enable DEMO_MODE=true for repeatable demos
