GLiClass vs Jev
Jev scores 62.1 (B) on agent readiness against GLiClass's 49.9 (D), and leads in 5 of 7 scored categories. GLiClass leads on payments & pricing and transparency & trust. Both do inference decision.
Which one, for what
GLiClass D
Good for Topic, intent and sentiment routing over a known label set on the owner's own CPU or GPU, where many labels must be scored at once.
Ahead on
- Payments & pricing, 60 against 20
- Transparency & trust, 64 against 56
Also in its favour
- No key needed to call it
- Open source
Watch for
No calibration evidence. The cards report F1 only, and the docs tell users to calibrate thresholds on their own traffic
Jev B
Good for High-volume yes or no answers, labelling, routing and rubric scoring where a probability is more useful than prose, such as ticket triage, invoice checks or picking a tool or skill from a list.
Ahead on
- Reliability, 60 against 43
- Schema & documentation, 87 against 49
- Agent ergonomics, 84 against 60
- Security & auth, 53 against 38
- Maintenance & community, 64 against 44
Also in its favour
- A hosted endpoint, with nothing to install
Watch for
Early access behind a waitlist, with no free tier or free credits found

Verdicts
GLiClass
An Apache-2.0 classifier that scores a whole label set in one encoder pass on the owner's hardware, with single-label, multi-label, hierarchical and few-shot modes. It returns label scores with no calibration claim, the bundled server has no authentication, and the last three test runs on the main branch, on 24 September 2026, failed.
Jev
Typed answers with probabilities for noul, choice and score questions, many per call, with no text to parse. Early access behind a waitlist, with no free tier or free credits found.
Before you call either
GLiClass
- Pass
--host 127.0.0.1topython -m gliclass.serve, or put the port behind your own gateway. The server checks no credential - On a machine without a GPU add
--device cpu --dtype float32 --num-gpus-per-replica 0. The default configuration expects CUDA - Send one text a request to
POST /gliclass. An array intextsis cut to its first item without an error - Set
multi_labelto false for one label from a set. The default scores each label independently, so scores do not sum to 1 - Keep text plus labels under the pipeline's 1,024-token
max_length, or useZeroShotClassificationWithChunkingPipeline. Longer input is truncated silently
Jev
- Put every independent question about one state into a single call. They run in parallel and the state is billed once
- Pin
jev-1.13.0instead ofjev-latestonce you've tuned confidence thresholds - Back off exponentially on 429 and 529. The limits move with demand
- Keep state to what the decision needs. Accuracy falls as unrelated content grows, and state plus the longest question must fit in 32,000 tokens
- Treat an answer about user-supplied text as a judgement that hostile text can steer, and cap what one answer can trigger
