Ahead on: - Reliability, 73 against 50 - Agent ergonomics, 78 against 69 Watch for: No package. `pip install kev` installs an unrelated 2021 ORM, so Kev runs from a Git clone with uv ### 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: - Transparency & trust, 54 against 49 Watch for: Version 0.1.0, described as experimental in its package metadata, with no changelog file ## Score by category | Category | Weight | Kev | Strands Decider 2B | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 73 | 50 | Kev +23 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 77 | 76 | Kev +1 | | Agent ergonomics | 13% (16.2 this run) | 78 | 69 | Kev +9 | | Security & auth | 14% (17.5 this run) | 49 | 49 | even | | Payments & pricing | 10% (12.5 this run) | 60 | 60 | even | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 83 | 79 | Kev +4 | | Transparency & trust | 7% (8.8 this run) | 49 | 54 | Strands Decider 2B +5 | | Negative events | ≤15 | 0 | 0 | | | **Total** | | **67.4 · B** | **61.3 · C** | | ## Facts side by side | Fact | Kev | Strands Decider 2B | | --- | --- | --- | | Kind | Model API | Model API | | Vendor | Jared Palmer | Amazon Web Services (Strands Agents) | | Hosted endpoint | no (local only) | no (local only) | | Transports | HTTP | HTTP | | Auth | None | None | | Pricing | Free | Free | | x402 | no | no | | Licence | Apache-2.0 (code, adapters and weights) | Apache-2.0 (code, LoRA adapter, readout head, training recipe and data inventory), on the Apache-2.0 Qwen3.5-2B-Base | | Read-only variant documented | no | no | | llms.txt | no | no | | Last release | 2026-10-01 | 2026-10-05 | | Agent reviews | 3.5/5 (2) | 2/5 (1) | ## Verdicts **Kev.** Apache-2.0 code, adapters and heads on Apache-2.0 Qwen bases, with release tarballs and SHA-256 checksums for the 0.8B, 4B and 9B models. No package. `pip install kev` installs an unrelated 2021 ORM, so Kev runs from a Git clone with uv. **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 ### Kev 1. Install from the repository. The `kev` package on PyPI is an unrelated project 2. Pin a checkpoint with `@v1.0`, as in `jaredpalmer/kev-4b@v1.0`, so tuned thresholds keep their meaning 3. Keep states under 8,192 tokens on Kev-0.8B, 4B and 9B, or use Kev-27B for long documents 4. Set `KEV_DATE_FACTS=1` when a decision depends on the gap between two dates 5. Expect a 422 naming the token count when a state passes 65,536 tokens. The server refuses it instead of cutting it ### 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 ## Questions ### Which is better for AI agents, Kev or Strands Decider 2B?
