Change the model in Agent Preferences at the top of the agent. Start with Recommended unless you already know you need more reasoning or more speed.
Models change often. New ones usually appear in Gumloop within a day of release. The in-product picker is the source of truth. The catalog on AI Models is a snapshot.

Where to change it

  1. Open the agent.
  2. Open Agent Preferences.
  3. Open the model dropdown.
Agent model picker with Recommended, Smartest, and Fastest presets

What to pick

Each preset points at a current best-in-class model that Gumloop updates for you. On Enterprise, admins can change which model each preset uses and hide models a custom role is not allowed to pick. To choose a specific model, search by name or browse by provider (Anthropic, OpenAI, Google, DeepSeek, MiniMax, Z.ai, and others).
Need vision (screenshots, images)? Pick a model whose card shows Vision. Almost every current agent model supports tool calling.

Cost

Agent model cost is token-based. You pay for the tokens in the conversation, plus compute and an orchestration fee. Open Chat Details on any run to see the exact spend. Full breakdown: Credits. To send model calls through your own provider key, see Use your own LLM key.
