Self-evolution
Sadie doesn’t just learn who you are. It also learns how it should behave for you: which prompt knobs, ranking weights, and selection thresholds produce output you actually keep. The Soul captures the you part. Self-evolution tunes the Sadie-for-you part.
Two learning loops
Section titled “Two learning loops”Soul is probabilistic and prompt-level. It flows into every chat turn and every generated brief as context. You can edit Soul directly in Memory.
Self-evolution is configuration-level. Changes produce versioned AgentConfig snapshots with parent pointers and a one-click rollback. Your Sadie is not a black box: every shift has a diff and a reason.
How it runs
Section titled “How it runs”Every user starts on a base Sadie configuration (v1). Activity accumulates XP weighted by signal strength (a rewritten brief is worth more than a dismissed one). When XP crosses a tier threshold, the self-evolution pipeline runs five stages:
- Reflect scans recent activity, brief engagement, discourse dismissals, and rewrite patterns. It produces evolution hypotheses like “briefs longer than 400 words get dismissed, candidate: lower
briefMaxPerRefresh”. - Select scores those hypotheses and picks the highest-confidence proposals within safe guardrails.
- Improve applies the selected proposals to the current config to produce a candidate snapshot.
- Evaluate replays the content generators against a real input corpus under both the current and candidate configs, producing a delta score and a safety assessment.
- Commit keeps the candidate if it scores higher and stays safe. Otherwise the candidate is rejected and the current config stands.
What gets tuned
Section titled “What gets tuned”The AgentConfig has three slots:
- Prompts: brief tone, discourse opener, chat hedging level, brevity hint.
- Weights: engagement scoring coefficients, wiki promotion threshold, brief cluster minimum size, discourse confidence floor.
- Policies: Today ranker coefficients (recency, confidence, novelty, dismissal penalty), emotion-pick threshold, freshness versus depth balance.
Version lineage and rollback
Section titled “Version lineage and rollback”Every committed change creates a new row in the agent versions table with a parent pointer. Settings shows the lineage and offers a one-click rollback to any previous version. If Sadie’s tone shifts in a direction you don’t like, you don’t have to reverse-engineer why. You roll back.
