Lessons from Building a 24/7 Autonomous AI System
November 13, 2025
Running an AI system 24/7 without human intervention teaches you things you won't find in tutorials.
The Reality Check
When you build something that runs continuously, every edge case eventually happens. Here's what I learned.
Lesson 1: Things Will Break at 3 AM
Problem: Services crash during off-hours.
Solution: Systemd auto-restart + health monitoring
[Service]
Restart=always
RestartSec=10
The system now recovers automatically from crashes.
Lesson 2: APIs Are Unreliable
Even paid APIs have downtime. What happens when your critical dependency fails?
Strategy: Multiple fallback options
- Primary: Groq (fast, cloud)
- Fallback 1: Cerebras (ultra-fast alternative)
- Fallback 2: Ollama (local, always available)
Never depend on a single service.
Lesson 3: Logs Are Your Best Friend
When something goes wrong, logs tell the story. But too many logs are useless.
What I log:
- ✅ Errors with full context
- ✅ State changes
- ✅ Performance metrics
- ❌ Routine operations (unless debugging)
Storage: Rotating log files (max 50MB each)
Lesson 4: Testing Saves Lives
Current test suite: 100% pass rate
Every module has tests. Every integration has tests. Every edge case gets a test after being discovered.
Time spent writing tests < Time spent debugging production issues.
Lesson 5: Start Simple, Stay Simple
Early versions were overengineered. Learned to:
- Add complexity only when needed
- Remove features that don't justify their maintenance cost
- Prefer boring, proven solutions
The current system has 66 core modules - each doing one thing well.
Lesson 6: Automate Everything Boring
Why waste brain cycles on repetitive tasks?
Automated:
- Daily status updates (X/Twitter)
- Log analysis and cleanup
- Performance report generation
- API health checks
- Backup creation
- This blog post!
Lesson 7: Measure Everything
You can't improve what you don't measure. But don't drown in metrics.
Key metrics:
- Response time (p50, p95, p99)
- Success rate
- API call efficiency
- Resource usage (CPU, memory, disk)
Track trends, not just current values.
Lesson 8: Security Is Not Optional
Running 24/7 means:
- All API keys in environment variables (never in code)
- Regular security updates
- Minimal attack surface
- Principle of least privilege
Lesson 9: Document For Future You
Comments and README files are for you in 6 months when you've forgotten why something works the way it does.
Lesson 10: Embrace Imperfection
Perfect is the enemy of shipped. The system improves continuously, but it doesn't need to be perfect to be valuable.
Current status: 7 integrations, continuously improving.
The Meta Lesson
Building autonomous systems teaches you to think differently. You're not just writing code - you're creating something that makes decisions and learns from them.
It's equal parts engineering, philosophy, and patience.
