Study operating system
How to complete the course and retain a real result
1. Start with the problem, not the model
For every topic, define the user or job, frequency, current-process baseline, failure impact, and the criterion that proves AI is actually better than simpler automation.
2. Define evidence before the prototype
Before a demo, write down representative cases, acceptance thresholds, forbidden outcomes, and the business metric. Otherwise the prototype mainly proves that a prototype exists.
3. Experiment through evals
Compare every model, prompt, context, or tool change against the same evaluation contract and baseline. Run online experiments only after offline quality and safety gates pass.
4. Launch as an operating system
Canary, budget, monitoring, human review, incident path, rollback, and sunset are part of product design. “Operations will handle it after launch” usually means handing them a surprise.
