Teach it

Teach it your labels. It tells you which answers to trust.

Show the server a few hundred of your own labelled examples. It learns what your labels mean, then marks every answer it is sure of. The model's weights never change.

  1. 1 Learn your labels
  2. 2 Draw the line
  3. 3 Route the answers

Two measured tasks. Learning: BANKING77 on the Gemma 4 31B, after 10 labelled examples per intent, mean of 3 draws, 150 test items. Certifying: support tickets across three queues on the Gemma 4 12B on a Mac, 400 labelled examples, half held back; the dots are its 200 answers on further tickets, one draw. decisio's own records at the pinned release: the Gemma 4 31B's intent heads (EVAL_CARD.md section 7.2) and the certified worked example (docs/tasks.md, runs/2026-10-14_certified-answers/).

10 per intent
  • BANKING77, 77 intents84.4%
  • CLINC150, 150 intents97.0%

Accuracy on the Gemma 4 31B, untaught and taught. Only measured amounts are shown: none, and 10 labelled examples per intent.

  1. Teach.

    Send labelled examples of your question. It takes minutes, and the weights stay as they are.

  2. Certify.

    The server holds half back and finds the confidence above which your wrong answers stay under a rate you pick.

  3. Act.

    Every answer says certified or not. Automate the certified ones and send the rest to a person.

It needs labelled examples, and a certificate holds for one task on one serving setup.

Intent accuracy on the Gemma 4 31B. BANKING77: 78.7% plain, 84.4% after 10 labelled examples per intent (mean of 3 draws, 150 test items). CLINC150: 94.0% plain, 97.0% after 10 labelled examples per intent (mean of 3 draws, 100 test items). These use labelled examples, so they compare the taught server with the untaught one, not with systems that see no labels.

How it works

Read once. Answer fast.

No training: one pass for each question.

One request carries a state and its questions.

The requestYour app sends one request with a state and its questions. Decisio reads the state once and, on the default Gemma 4 31B, scores the questions together in one batch; the response is a probability for every option, and the bars are a recorded answer.Your appa state, questionsPOST /v1/systemoneone requestDecisioone read, one batcha probability for every optionanswer0.96search0.01calculate0.02ask_user0.00act0.01

The state is read once, and the questions are scored together in one batch. A later request on the same state starts from the cache.

The cacheOn one 3,000-token document, Decisio 31B answers one question in 490 milliseconds, reading included, and fifty questions in one request in 1.08 s: it reads the document once and scores the questions together in one batch. A later, separate request on the same document starts from the cache and takes 32 to 43 ms (decisio 0.8.1, one RTX PRO 6000 at 585 W). The bars are to scale.One 3,000-token document, Decisio 31B, measured totals to scale (one box, 2026-10-11)1 question: 490 ms, read included50 questions: 1.08 sone read, one batcha later request on the same document, from the cache: 32 to 43 ms (decisio 0.8.1, one RTX PRO 6000 at 585 W)time

The exact wording, from the facts

On one box (one RTX PRO 6000 at 600 W, one session on 2026-10-11), Decisio 31B answered 50 questions about a 3,000-token document in 1.08 s and about a 6,000-token document in 1.73 s; Jeff-1.0-Large took 47.1 s and 114.6 s, and Quyet-1.0-Large 48.9 s and 114.8 s; neither accepts a 32,000-token document (Decisio 31B: 10.1 s). That is about 44 times (3,000 tokens) and 66 times (6,000 tokens) as long for Jeff-1.0-Large and Quyet-1.0-Large as for Decisio 31B.

On one box, the first question about a new 3,000-token document takes a median of 112 ms on H2O-Lightning-4B, 295 ms on Decisio 12B, 490 ms on Decisio 31B, and 895 ms on Jeff-1.0-Large and 895 ms on Quyet-1.0-Large.

The board, column by column

JevBench, axis by axis

Ten open-weights systems from the board's file in alphabetical order, and Jev 1.13.0 as a reference row; each cell is shaded by its value in the column. Higher is better on every axis.

Table of JevBench v1.6.1 scores for 11 rows: ten open-weights systems from the board's file and Jev 1.13.0 as a reference row, in alphabetical order, with six columns (overall, intelligence, sealed questions, calibration, speed, cost). Each cell is a plain value; the table has no shading or marks. Decisio 31B v0.8.0's values are overall 71.69, intelligence 70.4, sealed questions 73.3, calibration 88.7, speed 91.2, cost 51.7. The Decisio rows are the board's v0.8.0 entries: Decisio 31B v0.8.0 (71.69) and Decisio 12B v0.8.0 (68.17).

Routing

Use the probability

Keep the answers above a threshold you pick and send the rest to a person or a larger model. Example 5 measured what that buys.

Why

Why Decisio

  • Many questions, one read

    Every question in a request is scored from one read of your text: the same choice as one question at a time on every item measured, probabilities within 0.0073.

  • Long prompts, many options

    Prompts up to 32,768 tokens and 255 options per question.

  • Your hardware, no per-token bill

    It runs on your own GPU, Mac or laptop; the cost is the card, not a bill per token.

Demos

Watch it decide

Decisions in real time, from Decisio's own demos and one recorded run. Each clip is cut at the speed it happened. Nothing is sped up.

The driving clip draws map data from OpenStreetMap (ODbL, © OpenStreetMap contributors).

Honest limits

  • One box, one sessionEvery race figure is from one RTX PRO 6000 Blackwell Workstation Edition, power limit 600 W (default, enforced), each system on its own server.
  • One questionThe one-question figure in the hero is server time, on decisio 0.8.1's served defaults and one RTX PRO 6000 at 585 W, so a card at 600 W may read new states faster.
  • Time, not accuracyThe race compares how long fifty questions take, on synthetic support tickets.
  • Replayed, not liveThe race replays medians of 5 or 10 documents, and the demo replays decisions recorded on decisio 0.9.0.
  • A snapshot of the boardThe values are for JevBench v1.6.1; the live board has moved since.
  • HardwareGemma 4 31B needs a 96 GB card, or a 64 GB Mac.
