Which one, for what
Best for Self-hosted typed decisions over screenshots, documents and short video as well as text, where open weights matter.
Ahead on
- Reliability, 58 against 46
- Schema & documentation, 70 against 55
- Agent ergonomics, 72 against 66
Watch for
Released on 10 October 2026, with five tagged releases of each model by 11 October
Best 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
- Transparency & trust, 74 against 45
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

Verdicts
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.
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.
Before you call either
Decision 3.0
- Pin a tag or commit with
revision=when loading from the Hub. Each model had five tagged releases on 10 and 11 October - Send images and videos to
d3_server.pyas base64 data URLs only. The server refuses paths and http URLs with 422 - Set
DECISION_API_KEYbefore binding the bundled server beyond 127.0.0.1. It is open otherwise - Turn on
permutation_average=Truewhen routing must not depend on option order. It is off by default - Expect one request at a time from the bundled server. Use the router's model runtime for queued serving
Granite Switch 4.1
- Pass
chat_template_kwargs: {"adapter_name": "decision"}or"guardian-core". Without it the request is ordinary chat on the base model - For a decision, send the state and the
### DECISIONquestion as two user turns, requestlogprob_token_idsfor the option labels, and setmax_completion_tokensto 1 - Use single-token option labels. Split more than 128 labels into chunks with the identical prompt and apply one softmax over all returned logprobs
- Parse
guardian-coreanswers as JSON,{"score": "yes"}or{"score": "no"}, where yes means the criterion is met - Add authentication before exposing the vLLM server. Neither vLLM nor the checkpoint requires a key by default
