Introduction
LangSmith Agent Builder allows anyone to build an agent with a simple prompt. Ask it to build you a market research agent, and it will follow up with relevant questions to create what you need.
But sometimes you want to start with something that's ready to go. The Agent Builder Template Library expands tool integrations to help you get from idea to working agent even faster.
Agent Builder templates are prebuilt agents for common jobs, with tools connected and agent instructions included. They're ready to deploy and fully customizable. You can update your agent's instructions, add tools, and set approval requirements.
Unlike traditional workflow automations, you don't need to map every step and spend hours debugging changes. Just give your agent feedback like you would a teammate, and it learns.

Expanding Possibilities with Arcade
Agent Builder provides a set of ready-made tool integrations and templates. However, there are a nearly infinite number of tools your team may want to connect via MCP. Arcade's MCP Gateway makes an additional 8,000 tools available to Agent Builder for use cases spanning marketing, sales, recruiting, customer success, product, engineering, and general productivity.
To show what's possible, Arcade developed a collection of 60+ ready-to-deploy Agent Builder templates, available in their own hosted gallery. Each template includes a step-by-step guide to set up and start using your agent.
Choose the Best Model for Your Agent
Whether you're starting from a prompt or a template, different jobs may call for different models. Cost, latency, and reasoning requirements vary depending on whether your agent is summarizing emails overnight or responding to questions in real time.
That's why Agent Builder doesn't lock you into just one model. It supports OpenAI, Anthropic, and Google Gemini models, plus any custom or open source models that follow OpenAI or Anthropic specs.
Baseten built an agent using their GLM 4.7 model that responds quickly for real-time user interaction. Connect your preferred model provider to Agent Builder and start building.
