Google AI Studio tightens Gemini API errors

Solid devex work, and the kind that matters more than flashy model demos because it reduces friction in the loop where developers and agents actually fail.

• –The core shift is from vague “invalid request” responses to precise, machine-readable guidance.
• –The examples cover the most common failure modes: unknown fields, missing required fields, type mismatches, enum validation, and input-shape confusion.
• –This is especially useful for agentic coding flows, where the model can recover faster if the API tells it exactly what to change.
• –It also signals the Interactions API is still moving toward GA, so this is both a product improvement and a maturity marker.
