Hammerstein chat

Stateful strategic-reasoning conversations. Sonnet 4.6 wrapped in the Hammerstein system prompt. Paste a plan, draft a question, or open a thread — replies stream as they're written.

Each conversation has a $0.25 length cap; start a new one when you hit it. Your messages are stored against your subscription only; no training, no cross-customer access.

Subscriber access

Paste the access token Ray emailed you when you subscribed. Chat is a paid-tier surface — the token unlocks it (same token as the wargamer). Stored in this browser only.

Archive this conversation?

The conversation will be hidden from your list but kept on the server. Pick this if you're done — start a new conversation to continue talking.
