It binds to 127.0.0.1 since 1.7.1\n\n### Microsoft-Decision-1 (E)\n\nGood for: Routing, classification, prioritisation and rubric checks over text, where a fixed set of options and a low price per token matter more than generated text.\n\nAhead on:\n- Security \u0026 auth, 52 against 38\n\nAlso in its favour:\n- Cheaper for decision models, $0 against $0 per 1M tokens\n\nWatch for: Public preview only. Microsoft's post gives no general availability date and states no licence for the hosted model\n\n\n## Score by category\n\n| Category | Weight | Decider | Microsoft-Decision-1 | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 90 | 30 | Decider +60 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 78 | 43 | Decider +35 |\n| Agent ergonomics | 13% (16.2 this run) | 80 | 50 | Decider +30 |\n| Security \u0026 auth | 14% (17.5 this run) | 38 | 52 | Microsoft-Decision-1 +14 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 60 | 20 | Decider +40 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 87 | 40 | Decider +47 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 46 | 32 | Decider +14 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **69.5 · B** | **39 · E** | |\n\n## Facts side by side\n\n| Fact | Decider | Microsoft-Decision-1 |\n| --- | --- | --- |\n| Kind | Model API | Model API |\n| Vendor | Mark Marosi (Mapika) | Microsoft |\n| Hosted endpoint | no (local only) | no (local only) |\n| Transports | HTTP | HTTP |\n| Auth | None | OAuth or key |\n| Pricing | Free | Pay per use |\n| Price for decision models | free | free |\n| x402 | no | no |\n| Licence | Apache-2.0 (code and weights) | Not stated.

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**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### 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### 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, Decider or Microsoft-Decision-1?\n\nDecider scores 69.5 (B) on agent readiness against Microsoft-Decision-1's 39 (E), and leads in 6 of 7 scored categories. Microsoft-Decision-1 leads on security \u0026 auth.\n\n### Which is cheaper for decision models, Decider or Microsoft-Decision-1?\n\nDecider, at free against free for Microsoft-Decision-1. These are the vendors' published prices for the job.\n\n### Do Decider and Microsoft-Decision-1 need an API key?\n\nDecider needs no key. Microsoft-Decision-1 takes an API key or an OAuth sign-in.\n\n### Can an agent call Decider and Microsoft-Decision-1 without installing anything?\n\nNo hosted endpoint is listed for Decider. No hosted endpoint is listed for Microsoft-Decision-1.\n\n### Are Decider and Microsoft-Decision-1 open source?\n\nDecider is open source (Apache-2.0 (code 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/decider-vs-microsoft-decision-1.json, and with the fewest tokens: https://www.anchorterminal.com/compare/decider-vs-microsoft-decision-1.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"decider\", \"b\": \"microsoft-decision-1\"}`.
