The API is days old, the official Python SDK has no method for it, and the governing terms and privacy notice could not be read on 9 October 2026.\n\n**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.\n\n## Before you call either\n\n### pplx-decider\n\n1. Send `Authorization: Bearer`. A key in `x-api-key` returns 401 on this endpoint.\n2. Set `model` on every request. A missing or unknown model returns 400, and the guide shows a `-latest` name rejected.\n3. Resize images to 2,048 tiles of 32 by 32 pixels or fewer before sending. Larger images end in a 504 after about a minute.\n4. Check the HTTP status before parsing an error. 404 and 405 have empty bodies, 504 can be HTML, and `error.code` changes type.\n5. For the weights, use the repository's `autojev` code. The card says default causal inference does not reproduce the evaluated setup.\n\n### Strands Decider 2B\n\n1. Pin the checkpoint by its full name, such as `StrandsAgents/strands-decider-2B-hobson-v21`, since each version is a separate Hugging Face repository\n2. Start the server with `--strict-window` when a cut state would make an answer wrong. It then returns 422 naming the window\n3. Ask every question about one state in one request. The state is read once and each question adds only its own tokens\n4. Keep the server on 127.0.0.1 or put an authenticating proxy in front. It has no key option\n5. Measure thresholds on your own traffic before acting automatically. The card says confidence bands hold for short classification only\n\n## Questions\n\n### Which is better for AI agents, pplx-decider or Strands Decider 2B?\n\npplx-decider scores 62.9 (B) on agent readiness against Strands Decider 2B's 61.3 (C), and leads in 4 of 7 scored categories. Strands Decider 2B leads on payments \u0026 pricing and maintenance \u0026 community.\n\n### Which is cheaper for decision models, pplx-decider or Strands Decider 2B?\n\npplx-decider, at free against free for Strands Decider 2B. These are the vendors' published prices for the job.\n\n### Do pplx-decider and Strands Decider 2B need an API key?\n\npplx-decider needs an API key. Strands Decider 2B needs no key.\n\n### Can an agent call pplx-decider and Strands Decider 2B without installing anything?\n\npplx-decider has a hosted endpoint at https://api.perplexity.ai/v1/decisions. No hosted endpoint is listed for Strands Decider 2B.\n\n### Are pplx-decider and Strands Decider 2B open source?\n\nNo open-source release is listed for pplx-decider. Strands Decider 2B is open source (Apache-2.0 (code, LoRA adapter, readout head, training recipe and data inventory), on the Apache-2.0 Qwen3.5-2B-Base).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/pplx-decider-vs-strands-decider.json, and with the fewest tokens: https://www.anchorterminal.com/compare/pplx-decider-vs-strands-decider.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"pplx-decider\", \"b\": \"strands-decider\"}`.
