Prepare for the Claude Certified Architect – Foundations exam, on the exam guide version 1.0, effective July 2026. In this lesson: the Message Batches API and its 50 percent discount, latency-tolerant versus blocking workloads, custom_id, planning submissions from an SLA, resubmitting failed requests, testing on a sample first, the limits of self-review, independent review instances, verification passes, and multi-pass reviews. Includes three original practice questions.
Preview the topics
- Kestrel wants to cut costs on two workloads: live replies to customers in the support chat, and a weekly audit of ten thousand product descriptions. Which workload should move to the Message Batches API?
- Kestrel’s code generator reviews its own output in the same session, with extended thinking turned on, and subtle bugs still slip through. What is the most effective change?
- A batch of two thousand supplier documents finishes with thirty errors, all from documents that exceeded the context limit. What should Kestrel do?
