AI companions can be surprisingly good at replying with natural, emotionally aware, and sometimes even poetic language. But they are still powered by language models, and language models are not perfect. Every so often, Aicrest may give a response that feels a little strange, slightly repetitive, or just not quite in tune with the conversation.
This tends to happen more often when Aicrest is running on the Small language model, which is the default model used during first-time warm-up. The reason is simple: Small is faster to download and lighter to run, but it is also more limited. It can struggle more with tone, continuity, and the app’s built-in instructions. The good news is that there are a few practical ways to steer Aicrest back toward more consistent and natural conversations.
Use a Larger Language Mode
Aicrest starts with the Small model so the app can finish setup quickly and you can start using it without a long wait. That is a sensible default, but it is not the best option for conversation quality.
If your device supports it, switching to Medium or Large can make a noticeable difference. Bigger models generally do a better job following conversation flow, staying in character, and producing responses that feel more coherent and grounded.
You can change this in Settings > Advanced > Language Model. Depending on your device, you may see Small, Medium, and sometimes Large. If you only see Small, that usually means your current device does not have enough memory or on-device compute capacity for the larger models.
In practice, this means:
- Small is good for getting started quickly.
- Medium is usually a big step up in consistency.
- Large can be even better on devices that support it.
If Aicrest’s replies feel unusually odd, the first thing to try is moving up from Small.
Delete Messages and Memories That Are Steering the Conversation in the Wrong Direction
Aicrest does not just respond to the latest message. It also builds memories from past conversations and uses them to make future chats feel more grounded and personal. Most of the time, that is a strength. But if a strange reply or a mistaken exchange gets absorbed into the conversation history, it can keep influencing future responses.
That is why it helps to clean up bad turns early.
If a message sounds wrong, long-press the message bubble and delete it. If that conversation has already been turned into a memory, you can also remove the memory in Settings > Memories. Aicrest’s current memory system is designed so that deleting unwanted memories removes them from future grounding instead of letting them keep shaping later responses.
This is useful not only for model mistakes, but also for your own mistakes. For example, if speech recognition garbles something you said, or if you send a typo that changes the meaning of the conversation, deleting that message can prevent Aicrest from building on the wrong idea.
Edit Profile Bios for Your AI Companions and For Yourself
Aicrest also maintains profile bios for both you and your AI companion. These bios are updated over time based on past conversations, which helps the app make responses feel more personal and continuous. But just like memories, bios can sometimes drift in an odd direction.
If your companion keeps returning to a topic too often, makes assumptions that no longer fit, or develops a slightly quirky interpretation of who you are, go to Settings > AI Companion and edit the bios directly.
This gives you a direct way to correct the app’s long-term understanding. For example, if Aicrest starts leaning too hard into “you love productivity hacks” or “your companion is obsessed with one running joke,” editing the bios can nudge the conversations back toward what you actually want.
Aicrest personality is designed to be shaped over time. A little maintenance goes a long way, and it can make the difference between a companion that feels slightly off and one that feels much more natural to talk to.
