## Which one, for what

### Laya (B)

Good for: Fast, cheap classification and routing on short text in many languages, as a base to fine-tune on your own labels, and as an MCP or LangGraph routing step.

Ahead on:
- Reliability, 65 against 58
- Schema & documentation, 80 against 70
- Agent ergonomics, 80 against 72
- Transparency & trust, 62 against 45

Also in its favour:
- Runs on your own machine

Watch for: Base checkpoints score 0.362 and 0.352 on the maintainers' typed-decisions benchmark against a 0.318 random baseline, so it needs fine-tuning

### Decision 3.0 (B)

Good for: Self-hosted typed decisions over screenshots, documents and short video as well as text, where open weights matter.

Watch for: Released on 10 October 2026, with five tagged releases of each model by 11 October

## Verdicts

**Laya.** Apache-2.0 code and weights, installed with `pip install laya`, with Python 3.10 to 3.13 tested in CI. Base checkpoints score 0.362 and 0.352 on the maintainers' typed-decisions benchmark against a 0.318 random baseline, so it needs fine-tuning.

**Decision 3.0.** Open Apache-2.0 decision models that read images and video as well as text and answer several typed questions in one call, with a probability per option and tagged Hub releases. They are two days old, need a GPU and `trust_remote_code`, drop Vela's set and span types, and publish no calibration figures.

## Before you call either

### Laya

1. Set `LAYA_API_KEY` before starting `laya-serve`. It listens on every interface by default
2. Gate on `answer_confidence`, not `confidence`, which measures entropy and doesn't match Jev's field
3. Shortlist choice questions with more than about 20 options using `predict_shortlist` or the `laya_shortlist` tool
4. Use semantic or opaque labels such as `A` and `B`, not `yes` and `no`, in choice questions. The checkpoints can follow the label text
5. Pass `model="multilingual"` and `max_len=8192` for long documents. The English checkpoint stops at 512 tokens

### Decision 3.0

1. Pin a tag or commit with `revision=` when loading from the Hub. Each model had five tagged releases on 10 and 11 October
2. Send images and videos to `d3_server.py` as base64 data URLs only. The server refuses paths and http URLs with 422
3. Set `DECISION_API_KEY` before binding the bundled server beyond 127.0.0.1. It is open otherwise
4. Turn on `permutation_average=True` when routing must not depend on option order. It is off by default
5. Expect one request at a time from the bundled server. Use the router's model runtime for queued serving
