Timeout Fix Guide

Problem

Gemini API timing out with 504 errors after ~30 seconds.

Solution Applied ✅

1. Increased Timeouts

File: .env

BRAINSTORM_TIMEOUT=90  # Increased from 30s
ANALYZE_TIMEOUT=120    # Increased from 60s

2. Added Fast Mode

File: .env

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)

# In .env
FAST_MODE=true

• Faster responses (~10-20s per call)
• Shorter prompts
• Still high quality

Option 2: Full Mode (for production)

# In .env
FAST_MODE=false

• More detailed prompts
• Slightly better quality
• Slower (~30-60s per call)

Testing

Quick Test

# 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

# In .env, try:
GEMINI_MODEL=gemini-1.5-flash  # Fastest
# or
GEMINI_MODEL=gemini-1.5-pro    # Better quality, slower

3. Increase timeouts further

# 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:

# 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:

# 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:

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
