> Use https://docs.fastino.ai/openapi.json as the source of truth for customer-facing Fastino API routes. Only call operations present in that specification. Do not infer or call undocumented routes. Direct Fastino API integrations use https://api.fastino.ai, /v1 routes, and FASTINO_API_KEY.

# GLiNER-2.5-Decide

> Use typed decisions, constraints, extraction, relations, and structured records for low-latency decision-making.

GLiNER-2.5-Decide is a decision model for applications that need to make several related judgments from the same text. It combines typed decisions with explicit constraints, span extraction, relations, and structured records.

## Model capabilities and use cases

Decision models are particularly useful when software must make several related judgments from the same text. GLiNER-2.5-Decide supports use cases that require deterministic, low-latency decision-making.

1. **Model routing.** Route requests by destination, complexity, or escalation level. Return the selected route with probabilities and confidence scores.
2. **Tool calling.** Select from a permitted set of tools and capture arguments from the request as structured records.
3. **Browser and computer use.** Evaluate the current state to select the next action. Represent the action, target, and parameters as a structured record.
4. **Guardrails.** Evaluate safety, harm type, and escalation together, extracting harmful spans verbatim. Apply constraints when combinations of answers would be contradictory.
5. **Context pruning.** Decide which information in the context is relevant and return the exact character spans associated with that decision.
6. **LLM-as-a-judge.** Express rubric criteria as categorical or ordinal questions. Return selected values with probability distributions and confidence scores.
7. **Games and simulations.** Evaluate game state to determine intent, action, or outcome. Represent actors and state information through entities, relations, and structured records.
