 ## The Agent block
 
-You set up the reasoning step by giving the Agent block a **model** and a **prompt**. The model is the LLM that powers it; you pick one from the available providers, and the default is `claude-sonnet-5`. The prompt is a system message that defines who the agent is and how it should behave, plus a user message that carries the input, usually a reference like `<start.input>`.

The prompt is a system message that defines who the agent is and how it should behave, plus a user message that carries the input, usually a reference like `<start.input>`.
 
 When it runs, the Agent block reasons, calls any tools it needs, and stores its result under its own name. By default that result is free text in `content`, read by a later block as `<agent.content>`, alongside run details like the model used, token counts, tool calls, and cost. Every setting and output field is in the [Agent block reference](/workflows/blocks/agent).

 ### Model
 
-The model that runs the step. Defaults to `claude-sonnet-5`. Type or pick any model from OpenAI, Anthropic, Google, xAI, Groq, Cerebras, DeepSeek, Azure, AWS Bedrock, Google Vertex, or OpenRouter, or a local model through Ollama or VLLM.

 For a custom cloud deployment, enter its provider prefix and model ID: `azure/my-deployment`, `azure-anthropic/my-deployment`, `bedrock/my-inference-profile`, or `vertex/my-gemini-model`. The prefix selects the provider and shows its credential fields even when the ID is absent from the catalog. Bedrock accepts full inference profile ARNs after `bedrock/`; Vertex uses the Gemini API and accepts Google model resource names. The deployment must support the selected provider's API. Custom IDs have no catalog pricing or token limits.
