Thalamus

Most WeChat bots are reply pipes: silent until you speak, shapeless until you edit the prompt, and gone the moment the session ends. Thalamus is a DeepSeek Harness plugin that turns a dedicated WeChat account into an AI companion with her own personality, daily rhythm, long-term memory, and the habit of reaching out first.\n\nAt the heart of her is the World Engine, a nightly script run through a fully separate API call. It synthesises her character, six-axis temperament, interests, real weather, stable social circle, and recent memory to generate tomorrow's diary, sleep schedule, mood baseline, obsession topics, and slow-burn arcs. Layered on top are the six-axis personality engine derived from MBTI, a four-stage deformation state machine for arguments and reconciliation, bidirectional memory with an emotional filter, a promise ledger that tracks and fulfils commitments, a six-stage relationship progression where she picks her own pet names, and human-like sending rhythms. Every knob is exposed through an eight-tab admin console with two-level collapsing, so nothing lives in a black box.\n\nThis is a personal entertainment project, not a commercial product. It is for players who have a spare WeChat account, enjoy fine-tuning a character, and want a companion that feels lived-in rather than scripted. She cannot browse the web or make phone calls, but she remembers what she said, honours the promises she made, and will reach out when the conversation goes quiet.
