When you’d use this
- A better model for investigations. Set a stronger Primary for chats and RCAs.
- Lower cost on background work. Set a smaller Worker for triage and titles.
- Your data rules. Connect your own provider so model traffic goes to your account. This needs Business or Enterprise.
- One hard question. Pick a different model for one chat without changing anything for anyone else.


Set the default models
Default models has two roles. Each one has a model and a Reasoning level, for models that offer it.
New chats start on Primary. Automations use Primary or Worker unless a step names a model.
If you leave Primary empty, it uses RubixKube’s default. If you leave Worker empty, it’s the Same as Primary.
Admins change these and click Save. Everyone else can see what’s set.
Pick a model for one chat
Click the model picker in the chat box, or type/model. Your pick stays with that chat and doesn’t change anything for the organization. It follows the chat to any device.
If the model offers it, you can set Reasoning there too. Auto leaves it to the model.
Connect your own provider
Bring your own model when you need a model we don’t host, or want usage on your own account. This needs Business or Enterprise, and an admin. These providers are available:- Anthropic
- AWS Bedrock
- Google Gemini API
- Google Vertex AI
- OpenAI
- OpenRouter
- xAI
- Your own endpoint: any OpenAI-compatible server such as vLLM or LiteLLM, or your own Ollama
