When you use the Hatz AI Chat, you'll see something like this:
Selecting a Model with the Model Selector in Hatz
To open the model selector, click the model name at the top of your chat. This will open the All Models panel where you can browse and select from all available LLMs and Agents.
Filtering & Search You can search models by name or filter by use case — including Writing & Content, Code & Technical, Research & Analysis, Brainstorming, Use with Tools, Analyze Images & Docs, and more. You can also filter by platform.
Model Tiers Models are organized into two tiers:
Standard — Everyday models
Premium — Higher-capability models, noted as using more credits.
Pin Your Favorites The standout new feature is the ability to pin up to three LLMs and/or Agents directly to your chat interface for quick access. Each model has a pin icon next to it — click it to pin that model. In the screenshot, Claude Haiku 4.5 is shown already pinned (indicated by the filled purple pin icon). This means you can keep your most-used models just one click away without navigating back to the full selector each time.
