Hammerstein journal Writing on the Hammerstein framework, the benchmark, and what the AI is doing. 2026-07-03T16:00:00Z https://hammerstein.ai/journal/ Ray Weiss ray@hammerstein.ai https://hammerstein.ai/ Copyright 2026 Ray Weiss / Conflict Simulations Limited The dice are real. https://hammerstein.ai/journal/the-dice-are-real/ 2026-07-03T16:00:00Z 2026-07-03T16:00:00Z Every mode on hammerstein.ai now runs Sonnet 5, and a solo RPG GM mode opened at /rpg. Its dice are drawn from a tape fixed when the campaign starts, echoed in the mechanical log, and checked by the server before a turn stands. Cairn ships built in, alongside the GM’s own 2012 game. Three umpires shipped today. https://hammerstein.ai/journal/three-umpires-shipped/ 2026-05-21T16:00:00Z 2026-05-21T16:00:00Z A kriegsspiel umpire, a matrix-game referee, and a hosted chat. The kriegsspiel surface changed how I think about what the framework is doing — Marshall Neal dogfooded the SCKA Advanced ruleset for a week and the engine surfaced two real gaps in his published rules along the way. We pulled Grok aside and asked what it really thought. https://hammerstein.ai/journal/we-pulled-grok-aside/ 2026-05-13T12:00:00Z 2026-05-13T12:00:00Z The same Grok 4.20 model that called our benchmark “solid work” on X, in a private API call, called it “a specialized idiot-savant for this exact distribution.” Then it designed the test that would prove it. We ran the test.
