What it decides

Returns: A typed answer (choice, score or yes/no) with a probability for every question you pass, in one pass.
Checks: Routing, triage, scoring, yes/no questions and guardrails
Languages: English
Precision: 68 / 100 · 0.860 on English XNLI and 0.783 on English MASSIVE intent, but 0.362 zero-shot on typed-decisions (0.766 only after fine-tuning) (model card).
Clarity: Probability or score (15 of 15 clarity points)
How it runs: Labels spans or picks labels · reads the input once and writes nothing, so it answers in milliseconds.

Which apps can open a model depends on the files published for it: GGUF for llama.cpp-based apps, MLX for Apple’s engine, the original weights for vLLM and SGLang. Compare every app.

Memory and speed

Each precision on an NVIDIA GeForce RTX 4090, for one decision on a 256-token input. The best hardware table below covers other systems and devices.

Check it on your own hardware

Estimates come from published hardware specs and our open formulas, not from running the model on your machine. Real speed varies with runtime, drivers and settings. Numbers marked “Measured” come from a linked benchmark.
