Lesson & Term of the Day

Today's lesson

What is GPQA Diamond?

Learn what GPQA Diamond measures, why expert science reasoning benchmarks matter, and how they connect to frontier AI compute demand. Why it matters today: Today's lesson connects the Model Benchmarks & AI Compute Economics track to the compute market readers are watching.

Term of the Day

Structured outputs

Structured outputs make a model return data that follows a defined format, such as a JSON object with required fields. The shape is controlled, but the values still need checking. An invoice extractor returns amount, currency, and invoice number as separate fields rather than burying them in a paragraph.
