They are two days old, need a GPU and `trust_remote_code`, drop Vela's set and span types, and publish no calibration figures.\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### Decision 3.0\n\n1. Pin a tag or commit with `revision=` when loading from the Hub. Each model had five tagged releases on 10 and 11 October\n2. Send images and videos to `d3_server.py` as base64 data URLs only. The server refuses paths and http URLs with 422\n3. Set `DECISION_API_KEY` before binding the bundled server beyond 127.0.0.1. It is open otherwise\n4. Turn on `permutation_average=True` when routing must not depend on option order. It is off by default\n5. Expect one request at a time from the bundled server. Use the router's model runtime for queued serving\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, Decision 3.0 or pplx-decider?\n\nDecision 3.0 and pplx-decider score within a point of each other on agent readiness, 63.1 (B) and 62.9 (B). pplx-decider leads on schema \u0026 documentation, security \u0026 auth and transparency \u0026 trust.\n\n### Which is cheaper for decision models, Decision 3.0 or pplx-decider?\n\nDecision 3.0, at free against free for pplx-decider. These are the vendors' published prices for the job.\n\n### Do Decision 3.0 and pplx-decider need an API key?\n\nDecision 3.0 needs no key. pplx-decider needs an API key.\n\n### Can an agent call Decision 3.0 and pplx-decider without installing anything?\n\nNo hosted endpoint is listed for Decision 3.0. pplx-decider has a hosted endpoint at https://api.perplexity.ai/v1/decisions.\n\n### Are Decision 3.0 and pplx-decider open source?\n\nDecision 3.0 is open source (Apache-2.0 for the weights and the bundled runtime, built on Apache-2.0 Qwen3.5 and Qwen3.8 bases). No open-source release is listed for pplx-decider.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/decision-3-vs-pplx-decider.json, and with the fewest tokens: https://www.anchorterminal.com/compare/decision-3-vs-pplx-decider.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"decision-3\", \"b\": \"pplx-decider\"}`.
