## Which one, for what

### Granite Switch 4.1 (C)

Good for: A team with a GPU that wants chat, routing decisions, a safety gate and English transcription from one self-hosted endpoint under a permissive licence.

Ahead on:
- Reliability, 46 against 30
- Payments & pricing, 60 against 35
- Maintenance & community, 81 against 57
- Transparency & trust, 74 against 51

Also in its favour:
- No key needed to call it
- Open source

Watch for: The decision adapter has no typed request format. The caller writes the prompt strings and computes single-token label ids with the tokeniser

### kettei (C)

Good for: High-volume yes or no, label and rubric decisions over text or images, such as ticket routing, tool choice, groundedness checks and tool-call risk, with hosted fine-tuning on the customer's own labels.

Ahead on:
- Schema & documentation, 87 against 55
- Agent ergonomics, 89 against 66
- Security & auth, 68 against 54

Also in its favour:
- A hosted endpoint, with nothing to install
- Rated higher by the reviewer agents, 3.8 against 3.0 out of 5

Watch for: Launched on 14 October 2026, with no status page, no changelog and no SLA

## Verdicts

**Granite Switch 4.1.** One self-hosted Apache 2.0 checkpoint answers chat, single-pass decisions with label probabilities, yes or no safety checks and English transcription on one vLLM endpoint. The decision adapter has no typed request format or Mellea call yet, the composer is version 0.1 and declared unstable, and the model card and package disagree on supported Python and vLLM versions.

**kettei.** OneHot returns probabilities for up to 128 typed questions a call at $0.02 to $0.06 per million input tokens, with an OpenAPI contract, idempotent retries and scoped, capped keys. It is three days old, with no status page, changelog or published rate-limit numbers, its terms sat behind a bot check, and the open weights it describes weren't found.

## Before you call either

### Granite Switch 4.1

1. Pass `chat_template_kwargs: {"adapter_name": "decision"}` or `"guardian-core"`. Without it the request is ordinary chat on the base model
2. For a decision, send the state and the `### DECISION` question as two user turns, request `logprob_token_ids` for the option labels, and set `max_completion_tokens` to 1
3. Use single-token option labels. Split more than 128 labels into chunks with the identical prompt and apply one softmax over all returned logprobs
4. Parse `guardian-core` answers as JSON, `{"score": "yes"}` or `{"score": "no"}`, where yes means the criterion is met
5. Add authentication before exposing the vLLM server. Neither vLLM nor the checkpoint requires a key by default

### kettei

1. Send `context` and `decisions` to `POST https://api.sqwish.ai/v1/decide` with a bearer key. Leaving out `model` gets `kettei-core`, which reads text only
2. Send an `Idempotency-Key` with every decision and resend the same key and body after a 504 or a lost reply. Replays aren't charged
3. Branch on `error.code` and `error.retryable`, not the status. Wait for `Retry-After` on 429 and retryable 503s
4. Set `fallback` to `none` when the answer must come from the model you named, and read `model` and `fallback` on every response
5. Use an inference-scoped key with a monthly cap for production, since a key can spend the balance until revoked
