## Summary

The model takes text and a schema of typed questions and returns answers with probability distributions, confidence scores, and constraint-feasibility metadata. It is built on a DeBERTa-v3-large encoder, fine-tuned from gliner2-large-v1, and ships under the Apache 2.0 license. The model installs via pip and runs on CPU, GPU, or in air-gapped environments. Fastino also offers hosted inference and fine-tuning through its GLiNER API.

GLiNER2.5-Decide is a non-generative classifier that uses joint decoding to enforce rules across related answers, such as requiring an unsafe verdict when harm is detected. Fastino evaluated the model on its internal Fast Decisions suite of 5,100 test examples across 17 datasets. The model led on 9 of 17 datasets, scoring 75.3% on support intent and 64.3% on banking intent. Average exact-match accuracy was 60.1%. A 1B-parameter variant and a multilingual 287M model are also available.

## Key points

- Joint decoding enforces cross-answer rules for guardrails and routing

## Why it matters

A small, CPU-friendly model that returns structured decisions with confidence scores can replace LLM calls for routing, guardrails, and tool selection in agent pipelines, cutting cost and latency.
