- Day 31 · April 19, 2026The Agent Economy in PracticeSet a price per tool call (e.g. $0.001 for search, $0.005 for generate). Start 10× lower than you think -- agent
- Day 30 · April 17, 2026The Physical AI Wave: Humanoid Robots & VLA ModelsFor 26 days we studied how LLMs became agents. Today we arrive at the most dramatic frontier: agents that leave the cloud and enter the physical world.
- Day 29 · April 16, 2026The Frontier Race
- Day 28 · April 15, 2026Agentic AI in the Real World: Production Case Studies 2026After 24 days covering agentic AI theory, frameworks, safety, and infrastructure — today we ground it all in reality.
- Day 27 · April 14, 2026Self-Healing Agents in Production: Circuit Breakers and Drift DetectionPixVerse has taken over social media in April 2026 with its AI video effects that let anyone create cinematic, shareable videos in seconds.
- Day 26 · April 13, 2026Building Your First Production AgentUse the 6-step pattern: StateDict → node functions → conditional edges fi PostgresCheckpointer fi MCP tool wiring → compile. Start with a simple 3-node graph (plan → execute → evaluate) before adding complexity.
Takeaways of the week
- Physical AI = Agentic AI + Embodiment Every architectural pattern from the past 26 days applies to physical AI. The difference is that failures have physical consequences. Start thinking of robots as agents with bodies. Day 30
- VLA Models Are the New LLMs for Robotics Just as GPT-3 unlocked natural language agents, GR00T N1.7 and Helix are unlocking physical agents. Understand VLA architecture — it will be as foundational as transformers by 2027. Day 30
- Run the 8-Property Checklist Before Every Deploy Circuit breakers and loop detection take 30 minutes to add in LangGraph 2.0. Skipping even one of the 8 production properties is how agents become incidents. Day 28
- Start with Sequential Pipelines JP Morgan COiN proves sequential pipelines (Agent 1 → Agent 2 → Agent 3 → Human Review) are the safest and most auditable architecture. Use structured JSON handoff artifacts, not free text. Day 28
- Start with circuit breakers, not meta-agents When adding sel Start with circuit breakers, not meta-agents When adding self-healing to an existing agent, begin with circuit breakers on your most-used tools. This gives you 80% of the benefit in 20% of the time. Circuit breakers are stateless and easy to add without redesigning your agent graph. Save meta-agent supervisors for after you understand your actual failure patterns from Day 27
- Instrument drift detection before you need it Add cosine sim Instrument drift detection before you need it Add cosine similarity tracking between your agent's declared goal and its recent actions from day one -- before you hit a context drift incident. Once you're chasing a production bug, you won't have the traces you need. Use OTEL to emit a 'goal_alignment_score' attribute on every agent step. Set an alert at <0.7. Treat checkpoint storage as critical infrastructure Your agent checkpoints are as important as your database backups. Store them in a durable, versioned store (PostgresCheckpointer or Redis with AOF persistence). Test your recovery path monthly -- if you've never actually restored from a checkpoint in a drill, you don't know if it works. HyperAgents: watch the self-improvement frontier Meta's HyperAgents paper shows that the gap between 'self-healing' (reactive) and 'self-improving' (proactive) is closing fast. Start familiarising yourself with the Darwin Godel Machine architecture. In 12-18 months, production agents that improve their own code will be a real engineering decision, not a research Day 27
