Default Assistant Model

Configure the default model for new conversations, affecting initial user experience and API costs.

Definition: When a user starts a new chat or creates an assistant without specifying a model, the system uses this default.

Business impact: This is the first impression of user experience. It determines the intelligence for casual queries.
Recommendations:
- Experience-first: Choose a strong flagship model like DeepSeek-V4-Pro or GLM-5.2 for high-quality first impressions.
- Cost-effective: For high concurrency, choose a "sweet spot" model like DeepSeek-V4-Flash to balance speed and cost.

Default Model Settings

Configure default AI models for the system, including assistant, topic naming, and translation models, balancing user experience and operating costs.

Topic Naming Model

Configure the model that auto-summarizes conversations into short titles. A lightweight model is recommended.
