Available models
Every agent starts on GPT-5.6 Luna, the platform default. Selecting another
model overrides the default for that agent until you clear the selection.
Every business can select any listed model. Token usage is converted
into Bizzy credits. See Admin Guide → Billing
for details.
Picking a model
- Leave the model blank to use GPT-5.6 Luna and follow future changes to the platform default.
- Select Claude Haiku or Gemini Flash when response time and cost matter more than reasoning depth.
- Select Claude Sonnet or Claude Opus when you prefer Claude for the agent’s task.
Changing the model
Set Model when creating an agent, or leave it blank to use the platform default. Each new conversation uses the agent’s current model and keeps that model for its entire life. Changing the agent’s model does not affect existing conversations.Next steps
