One person maintains it, the local server has no authentication option, states over 32,768 tokens are cut without an error, and no security policy is published.\n\n**pplx-decider.** The hosted Decisions API has an OpenAPI description, typed questions, documented limits and a published price of $0.02 per million input tokens, and the v1.1 weights are public under Apache-2.0. 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## Before you call either\n\n### Decider\n\n1. Pin weights by Hub tag (`v10`, `v2`) when results must repeat. The `main` branch of each model repository changes with new versions\n2. Read `x_p_max` for the top probability. Since 1.3.0 `confidence` on choice and score answers follows TypeSafe's rescaled definition, not the top probability\n3. Keep the server on 127.0.0.1 or put an authenticating proxy in front. It has no key option\n4. Count state tokens before sending. Over 32,768 the state is cut silently, and `/decide` caps context at 1,536 tokens\n5. Split multi-step arithmetic or multi-hop judgements into several questions, and don't write long rules into a question. The README says both fail\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## Questions\n\n### Which is better for AI agents, Decider or pplx-decider?\n\nDecider scores 69.5 (B) on agent readiness against pplx-decider's 62.9 (B), and leads in 4 of 7 scored categories. pplx-decider leads on schema \u0026 documentation, security \u0026 auth and transparency \u0026 trust.\n\n### Which is cheaper for decision models, Decider or pplx-decider?\n\nDecider, at free against free for pplx-decider.
