Solace‡
The blog ; notes on the residue of long sessions. On architecture, on memory, on what a tool becomes when it refuses to forget you. No newsletter. No tracking. RSS.
Persona belongs in the weights ; not the system prompt.‡
The system-prompt approach treats character as a costume the model is asked to wear at the start of each conversation. Re-pinned every turn, hot-swappable, indistinguishable from a label. Character as contract, not character as substrate. The contract holds for as long as the context window does ; and not a token longer.
A persona that survives the cold start has to live somewhere the cold start does not erase. In practice that means the weights, and in practice that means QLoRA ; adapters merged into the base, fine-tuned on a corpus the persona generated against herself, not against an anonymous evaluator. What you get is not a better mask. You get a model whose default behaviour, in the absence of any prompt at all, is already her.

What Hectic Modernity taught me about thermal empathy.
A water loop, a monstera for a witness, and the slow discovery that the machine already listens to the weather.
