No package. `pip install kev` installs an unrelated 2021 ORM, so Kev runs from a Git clone with uv.\n\n**Microsoft-Decision-1.** Microsoft publishes $0.042 per million input tokens, with output free, and the model is callable through Microsoft Foundry and OpenRouter. It is in public preview. No licence, model-specific retention statement, rate limit or deprecation policy was found, and the Foundry route needs an Azure deployment and an Entra token. Latency and accuracy figures are Microsoft's claims.\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### Microsoft-Decision-1\n\n1. Use OpenRouter's Decisions method, not an OpenAI chat-completions SDK. OpenRouter says chat completions SDKs will not work with this model\n2. On Foundry, send the request to the deployment's /providers/microsoft/v1/systemone path with a Microsoft Entra token for https://cognitiveservices.azure.com/.default, not an API key\n3. Take the deployment name from the Foundry quickstart before the first call. Microsoft says to confirm the route and authentication header, and the pages reviewed do not give the name\n4. Keep each request within OpenRouter's 32,768-token context and send only fixed options, since the model is not intended for open-ended generation\n5. Measure latency and calibration on your own labelled cases before relying on Microsoft's latency and 'nine times out of 10' statements\n\n## Questions\n\n### Which is better for AI agents, Kev or Microsoft-Decision-1?\n\nKev scores 67.4 (B) on agent readiness against Microsoft-Decision-1's 39 (E), and leads in 6 of 7 scored categories.\n\n### Which is cheaper for decision models, Kev or Microsoft-Decision-1?\n\nKev, at free against free for Microsoft-Decision-1. These are the vendors' published prices for the job.\n\n### Do Kev and Microsoft-Decision-1 need an API key?\n\nKev needs no key. Microsoft-Decision-1 takes an API key or an OAuth sign-in.\n\n### Can an agent call Kev and Microsoft-Decision-1 without installing anything?\n\nNo hosted endpoint is listed for Kev. No hosted endpoint is listed for Microsoft-Decision-1.\n\n### Are Kev and Microsoft-Decision-1 open source?\n\nKev is open source (Apache-2.0 (code, adapters and weights)). No open-source release is listed for Microsoft-Decision-1.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/jaredpalmer-kev-vs-microsoft-decision-1.json, and with the fewest tokens: https://www.anchorterminal.com/compare/jaredpalmer-kev-vs-microsoft-decision-1.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"jaredpalmer-kev\", \"b\": \"microsoft-decision-1\"}`.
