Google Vertex AI / Gemini structured output

Unverified

Constrain Gemini output to an enum or JSON schema and read logprobs; Model Armor for safety screening. Versioned model IDs.

What it does

  • Constrain Gemini output to an enum or JSON schema and read logprobs; Model Armor for safety screening. Versioned model IDs.

Pricing

  • Per-token (rates not re-checked). [NOT re-verified on 2026-10-15 — carried from prior research; check before relying on it]

Limits

  • Not recorded. [NOT re-verified on 2026-10-15 — carried from prior research; check before relying on it]

Status

  • Previously recorded as generally available. [NOT re-verified on 2026-10-15 — carried from prior research; check before relying on it]

Safety & fit notes

  • Enum + logprobs approximates a choice API; calibration is yours to measure.
  • Same pattern applies: deterministic rules own hard constraints; the model is advisory; fail closed on errors.
