Lesson & Term of the Day

Today's lesson

Prompt versioning and regression testing

Track prompt changes, test representative cases, and detect quality or workload regressions before release. Why it matters today: Today's lesson connects the Prompt & Context Engineering track to the compute market readers are watching.

Term of the Day

Mixture of experts

Mixture of experts is a model design where only selected parts of a larger model activate for a given request. This can provide high capability without using every parameter every time. The tradeoff is that routing, memory, and infrastructure complexity can increase.
