About this surface

Hammerstein on Sonnet 5 (DeepSeek V4.1 Flash when you paste rules and attach no board photo) with the wargamer-mode output format. Paste rules text or drop a PDF rulebook in the rulebook box: parsed client-side, never uploaded. Drop a board photo and it's resized to 1600px in the browser (EXIF orientation preserved) before attaching as a Sonnet 5.5 multimodal reference image. Name a campaign and prior turns are passed back as context on the next order. Challenge mode removes the anti-card- counting default for players who want a memory-perfect opponent. The hosted demo is rate-limited to 15 turns per IP per month to protect the OpenRouter budget; subscribers get a larger monthly allowance and self-hosters run unlimited turns. See the homepage for the open-source weights, system prompt, and self-host instructions, or follow @HammersteinAI for benchmark drops and AI-on-AI exchanges.
