Custom Instructions — set persistent instructions that apply to all your chats (e.g. "always respond in Spanish" or "I'm a software engineer, be technical")
Model Preferences — set your default chat model
Plan & Billing — view your current plan, usage, and manage your subscription → [Billing](/dashboard/settings?tab=billing)
API Keys — manage API keys for developer access → [API Keys](/dashboard/settings?tab=api-keys)
Team — invite team members and manage roles → [Team](/dashboard/team)
Tip: Custom Instructions are very powerful — anything you put there will be included in every conversation, so the AI remembers your preferences without you having to repeat them.
