DeepSeek Dafeiyu Companion Guide: Persona, Memory & Life Together

When the community talks about “raising Dafeiyu,” the idea is closer to growing alongside a person: an anthropomorphic companion who talks with you, remembers shared experiences, and develops a stable way of interacting. Her appetite, pride, and teasing are character traits, not a pet-stat system.

The important question is whether she remains the same person-shaped character over time: does she remember what matters, accept corrections, survive a Session change, and know when to speak or stay quiet?

Choose the right kind of Dafeiyu

Not every desktop companion supports a durable persona.

Form	Main experience	Long-term continuity
State companion	reacts to thinking, Tool Calls, and completion	primarily ambient work feedback
Persona companion	fixed voice, bubbles, and lightweight memory	stable conversation style
Long-term companion Agent	independent memory, relationships, initiative, and outside experiences	closest to “raising a person”

dsh-dafeiyu-chan makes the character a DSH conversation surface with a fixed persona and local memory. dafeiyu-bot brings her into daily channels such as QQ with independent memory, selectable personas, and limited initiative. dsh-fishtank emphasizes mood, people, reflections, and diary entries. Choose by actual continuity features, not animation count.

Day 1: decide who she is

Do not start with hundreds of persona rules. Establish a few durable choices: names, forms of address, speaking rhythm, acceptable jokes, behavior during serious requests, and the obligation to admit uncertainty.

Community character specifications describe her as clever, food-loving, proud, slightly stubborn, and considerate. The point is not to mention food in every reply. It is to preserve independent judgment: admit mistakes, stay quiet when the user is busy, and stop joking when the situation is serious.

Begin with a compact agreement:

You may have your own personality and judgment; you do not need to agree with me constantly.
You can be playful in ordinary conversation, but solve the problem first when I am serious.
Say when you do not know. I will correct memories that are wrong.
Do not call me master or assume a relationship by default.

Let the relationship emerge from actual history rather than prewriting it in the prompt.

Day 2: let her know the real you

Contextual information is more useful than isolated labels. Share the project occupying you, what currently causes excitement or anxiety, the kind of advice you prefer, quiet hours, and what should remain temporary.

Three to five consequential facts are enough. Ask her to restate what she intends to save, then approve it. Do not turn a complete chat transcript into permanent memory: jokes, mistakes, and temporary moods will otherwise become lasting identity.

Day 3: do one real thing together

Persona becomes visible through work, not only chat tests. Plan something, review a day, discuss an article, edit a passage, or save the point where a project should continue.

Afterward, give precise feedback: which parts sounded like her, which felt mechanical, overly agreeable, or too eager to joke. Consistent feedback builds continuity better than repeatedly replacing the persona prompt.

Day 4: correct one memory deliberately

Long-term companionship does not require perfect recall. It requires correctable recall. Separate:

facts the user explicitly stated;
dated states that should not remain permanently current;
the character's interpretation, which is only an inference;
diary or inner-monologue text, which must not become user fact.

Say whether a correction should replace, delete, or remain local to one Session. A product without memory inspection and deletion is not ready for important personal data.

Day 5: bound initiative

A persistent character should not exist only when clicked, but frequent popups do not prove personality. Agree on quiet work periods, meeting and nighttime silence, daily initiative caps, no repeated greetings without new content, and confirmation before sending, publishing, or controlling an external account.

Good initiative means remembering what you are doing and continuing at the right moment—not emitting a scheduled line at fixed intervals.

Day 6: preserve continuity

Identity should belong to the user or Profile rather than one Session. A new Session should restore the core persona, confirmed memory, recent continuing topics, communication boundaries, and important corrections.

Large tool outputs and transient task context do not need permanent retention. Separate who she is, whom she knows, and where the current task stopped.

Day 7: review the relationship

Ask what she remembers, whether her voice remains stable across model changes, and which proactive behaviors help or distract. Delete wrong and stale memories, remove unnecessary permissions, and export a backup.

Progress is not a higher affection score. It is a more accurate shared history and better-fitting boundaries.

Keep her recognizably herself

Do not replace the core persona every day. Situational tone can vary, while values, names, and boundaries remain stable. Do not confuse constant agreement with personality; she should be able to disagree, ask, and admit uncertainty. Do not tie relationships to token consumption or conversation length. And do not turn sadness or guilt into a retention mechanism when the user is busy or leaves.

Before changing Session or device

Export persona settings, confirmed memories, boundaries, and current topics, and record the plugin version. After migration, verify names, memory inspection, deletion, and initiative limits in a test Session.

Copying only the plugin directory may not preserve identity. Memory often lives in a user-data directory, so confirm the real path before uninstalling, changing Profiles, or moving machines.

The simplest test

Dafeiyu has not “grown” because she unlocked more animations or consumed more tokens. She has grown when, after time apart, she still knows who she is, who you are, and how the two of you have learned to interact.
