Key takeaway
Choose a model on AI Fengyue by use case: for casual chat, prefer fast, low-cost models; for long plots and rich description, pick models that write better; when testing a new character card, debug with a light model first. Model names and costs are shown on the platform.
AI Fengyue supports multiple AI models, and "Recent updates" on the official site mentions newly added models such as One_Grok. More models is a good thing, but it can confuse beginners: which one should you pick? This article does not give a "strongest model ranking" (model performance changes with updates, and we will not make up benchmark data); instead, it shows you how to choose by use case.
Ask yourself three questions first
- What is the goal of this conversation? Casual chat, writing a long story, or testing a new character?
- Do I care more about reply speed or writing quality?
- What is my point budget?
Choosing a model by use case
The table below illustrates the approach; it is not a measured ranking:
| Use case | Prioritize | Acceptable trade-off |
|---|---|---|
| Casual chat | Fast replies, low point cost | Simpler writing style |
| Long-form story writing | Rich prose, good context understanding | Slightly slower, possibly higher cost |
| Testing a new character card | Low cost, easy to retry many times | Reply quality is not the main goal |
| Complex world reasoning | Logic and consistency | Needs a clearer lorebook alongside it |
A practical approach: compare on the same scene
The most reliable way is to test it yourself. Pick a fixed opening and three rounds of input, run them through two or three models, and see which best matches how you imagine the character. Note each one's strengths and weaknesses so you can switch quickly by scene later.
Keep your input identical when testing, or the comparison is meaningless.
What to watch for when switching models
When you switch models mid-conversation, the new model reads the current context and continues, but the writing style may change. If the change is noticeable, edit a reply or two to "pull the style back", or add more specific speaking style details to the character card.
Common misconceptions
Myth 1: "The most expensive model is always best." The best model is the one that fits the use case; using an advanced model for casual chat may just cost more points.
Myth 2: "Online model rankings apply to every scenario." Model performance depends on genre, setup and writing, and changes between versions.
Myth 3: "Switching models solves memory problems." Models may have different context lengths, but none has permanent memory.
Safety reminder
Safety reminder: never enter real ID numbers, home addresses, bank cards or payment passwords in chats. Only access the platform via fyue.app and never download or install unofficial "cracked" or "no-login" versions. AI-generated content can be wrong — do not treat it as professional advice.
