Gemini Decisions API

What HN thinks

Google arrives fashionably late to the yes/no party, carrying a Bernoulli pun and a slightly higher bill.

Decision models are genuinely useful
Many commenters use Jev-style decision APIs for gating, triage, routing, guardrails, labeling and evals, praising their speed and tiny token cost.
Calibration is the real product
Raw LLM logprobs or constrained outputs are poorly calibrated after RLHF, so well-calibrated probabilities are what distinguishes these APIs, though some call the methods unprincipled.
Skepticism about Google and pricing
Some see a me-too enterprise wallet play that's pricier than rivals and fear Google will kill it, while others report strong multimodal results and better Brier scores than Jev.

Consensus: Most agree decision models fill a practical niche for cheap, fast classification, but there's no consensus on whether Google's offering beats Jev or justifies its price.

MediaPipe Decision Maker ↗ (library): Suggested as an existing local alternative from Google.
Jeffy Classify ↗ (tool): Recommended for local, private, fast classification with n8n integrations.
Natural language inference models (other): Suggested for doing Jev-like decisions with smaller models.
Artificial Analysis Decision Index ↗ (service): Cited for comparing price versus quality across providers.
