## Which one, for what

### Celeris-1 Decision (D)

Good for: Multimodal classification, routing and bounded decisions with probabilities and optional explanations

Also in its favour:
- Cheaper for inference decision, $0 against $0 per 1M tokens
- A hosted endpoint, with nothing to install

Watch for: Early-access terms and capacity-dependent workspace activation

### 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 40
- Schema & documentation, 80 against 60
- Security & auth, 57 against 45
- Payments & pricing, 60 against 20
- Maintenance & community, 83 against 40
- Transparency & trust, 62 against 53

Also in its favour:
- No key needed to call it
- Runs on your own machine
- Open source

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

## Verdicts

**Celeris-1 Decision.** Typed probabilities, image inputs and optional explanations suit routing and classification inside an agent. Both System One and OpenAI Decisions request formats are documented. The service remains early access under its terms, activation can queue, and prepaid credit expires after 30 days. The published accuracy and latency figures are Celeris measurements, not Anchor Terminal tests.

**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.

## Before you call either

### Celeris-1 Decision

1. Use the decision model path and matching model field. This model has no chat, Responses or models endpoint.
2. Use at most 512 questions per request, or 64 with explanations. Both endpoints reject streaming.
3. Preserve x_celeris in a custom Jev SDK response model when reading explanations. The default response type drops it.
4. Retry 429 with Retry-After and backoff. Stop on 402 until workspace credit is replenished.
5. Read usage.input_tokens for cost, including images and request overhead. Track credit expiry separately from token consumption.

### 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
