GLiClass vs Strands Decider 2B

Strands Decider 2B scores 61.3 (C) on agent readiness against GLiClass's 49.9 (D), and leads in 5 of 7 scored categories. GLiClass leads on 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

  • Transparency & trust, 64 against 54

Watch for

No calibration evidence. The cards report F1 only, and the docs tell users to calibrate thresholds on their own traffic

Strands Decider 2B C

Good for Cheap, local classification, routing, triage and tool-call checks on short text inside Strands or other Python agents, and for teams who want to retrain a decision model from a published recipe.

Ahead on

  • Reliability, 50 against 43
  • Schema & documentation, 76 against 49
  • Agent ergonomics, 69 against 60
  • Security & auth, 49 against 38
  • Maintenance & community, 79 against 44

Watch for

Version 0.1.0, described as experimental in its package metadata, with no changelog file

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.

Strands Decider 2B

A 1.9B-parameter Apache-2.0 decision model that runs on a laptop GPU, an Apple silicon Mac or a CPU, with its training data, recipe and per-version results published. It's an experimental 0.1.0 release with a 4,096-token window that cuts long states by default, and its local server has no authentication.

Before you call either

GLiClass

  1. Pass --host 127.0.0.1 to python -m gliclass.serve, or put the port behind your own gateway. The server checks no credential
  2. On a machine without a GPU add --device cpu --dtype float32 --num-gpus-per-replica 0. The default configuration expects CUDA
  3. Send one text a request to POST /gliclass. An array in texts is cut to its first item without an error
  4. Set multi_label to false for one label from a set. The default scores each label independently, so scores do not sum to 1
  5. Keep text plus labels under the pipeline's 1,024-token max_length, or use ZeroShotClassificationWithChunkingPipeline. Longer input is truncated silently

Strands Decider 2B

  1. Pin the checkpoint by its full name, such as StrandsAgents/strands-decider-2B-hobson-v21, since each version is a separate Hugging Face repository
  2. Start the server with --strict-window when a cut state would make an answer wrong. It then returns 422 naming the window
  3. Ask every question about one state in one request. The state is read once and each question adds only its own tokens
  4. Keep the server on 127.0.0.1 or put an authenticating proxy in front. It has no key option
  5. Measure thresholds on your own traffic before acting automatically. The card says confidence bands hold for short classification only

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
