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### Kev\n\n1. Install from the repository. The `kev` package on PyPI is an unrelated project\n2. Pin a checkpoint with `@v1.0`, as in `jaredpalmer/kev-4b@v1.0`, so tuned thresholds keep their meaning\n3. Keep states under 8,192 tokens on Kev-0.8B, 4B and 9B, or use Kev-27B for long documents\n4. Set `KEV_DATE_FACTS=1` when a decision depends on the gap between two dates\n5. Expect a 422 naming the token count when a state passes 65,536 tokens. The server refuses it instead of cutting it\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, Kev or pplx-decider?\n\nKev scores 67.4 (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 and security \u0026 auth.\n\n### Which is cheaper for decision models, Kev or pplx-decider?\n\nKev, at free against free for pplx-decider. These are the vendors' published prices for the job.\n\n### Do Kev and pplx-decider need an API key?\n\nKev needs no key. pplx-decider needs an API key.\n\n### Can an agent call Kev and pplx-decider without installing anything?\n\nNo hosted endpoint is listed for Kev. pplx-decider has a hosted endpoint at https://api.perplexity.ai/v1/decisions.\n\n### Are Kev and pplx-decider open source?\n\nKev is open source (Apache-2.0 (code, adapters and weights)). 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/jaredpalmer-kev-vs-pplx-decider.json, and with the fewest tokens: https://www.anchorterminal.com/compare/jaredpalmer-kev-vs-pplx-decider.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"jaredpalmer-kev\", \"b\": \"pplx-decider\"}`.
