Facts are extracted during the conversation and kept, not re-read from a transcript. The model knows your sister's name, your commute and what you said last month.
Every turn updates an estimate of how the exchange is going. Mood is a control signal, not a label: it sets latency, openness and how much the model volunteers.
Behaviour has a cost. Push the conversation far enough negative and the character replies late, stops replying, or blocks you. Earn it and it answers faster, at 02:00, unprompted.
Pelagea is research-stage. Access is API only, granted in small cohorts, and the waiting list is the only way in. Tell us what you intend to measure and we will write when a key is free.
