Quickstart

How to use the Gemini Decision 1 API

  1. 1

    Create a free CompanyFabric account, starter credits are included, no card required.

  2. 2

    Copy your API key from the dashboard. One key covers every model in the library.

  3. 3

    POST /v1/decisions with "google/gemini-decision-1", a state (text or JSON) and typed questions (noul, choice, score). The answer is probabilities, not text, so there is nothing to parse.

  4. 4

    Read the exact metered cost of the call from the response, the same number shown in the playground.

Use cases

What teams build with it

Support triage

Category, urgency and escalate-to-human as probabilities in one call, before any model drafts a reply.

Agent gates

Should this step call a tool, escalate to a frontier model, or stop and ask? Decide first, spend second.

Moderation & claim checks

Is this a health or income claim, is this a threat, is this spam. Typed answers you can threshold and audit.

Scoring & prioritisation

Prompting tips

  • Ask many questions in one call; answers come back in parallel and the state is sent once.
  • Describe each choice label in criteria. A described option is a better-calibrated option.
  • Treat a noul near 0.5 as unsure and fail closed; ship thresholds as config and tune from the log.

Exact, metered, prepaid

Gemini Decision 1 pricing

Gemini Decision 1 pricing is per token: $0.1 / M input · $0 / M output. Output tokens cost 0× input tokens, so long generations, not long prompts, are what actually drive most bills. A typical call with a 2k-token prompt and a 1k-token answer costs about $0.0002.

Every call is metered exactly and attributed to your key, the dashboard, the API usage response, and your invoice all read from the same ledger row. Cap any key's monthly spend with a budget cap, and bring your own provider key (BYOK) at 0% platform fee if you already have a direct contract.

Starter credits

Use Gemini Decision 1 free

Your CompanyFabric starter credits cover your first Gemini Decision 1 calls at no cost, create a free account, no card required, and the credits apply to Gemini Decision 1 and every other model on the key. When they run out, prepaid credits or BYOK (0% fee) take over with no plan to pick.

FAQ

Frequently asked questions

How much does the Gemini Decision 1 API cost?

$0.1 / M input · $0 / M output. Every call is metered exactly and shown before you run it.

How do I get a Gemini Decision 1 API key?

Create a CompanyFabric account, and one key unlocks Gemini Decision 1 and every other model in the library. Free starter credits are included, no subscription, no card required to try it.

Why use Gemini Decision 1 on CompanyFabric instead of going direct?

One key, one prepaid balance, and one rate-limit envelope across the whole library, at pricing at parity with or below the direct API. Model switching is a one-line change, and BYOK routing is 0% fee.

Is the API OpenAI-compatible?

No, and on purpose: a decision model takes state plus typed questions and returns probabilities, which no chat shape expresses. POST /v1/decisions with "google/gemini-decision-1", a state (text or JSON) and typed questions (noul, choice, score). The answer is probabilities, not text, so there is nothing to parse. Same key and same balance as the chat models.

Can I use the output commercially?

Commercial use per Gemini API paid-tier terms; Google does not use paid-tier prompts to train its models.

How does billing work?

Prepaid credits via card, or BYOK with your own provider keys at 0% platform fee. No subscription required; balances never expire.
