Build Your AI Agent with AgentKit

Build agents with OpenAI's development tools. We scope the workflow, connect the required systems, and test the agent's responses and actions before deployment.

Scope, milestones, and responsibilities agreed before the build.

How we work

From the first question to working software

Conceptual workflow. Conceptual illustration of three connected stages.

Capabilities

What we can build with you

Choose the work your project needs. We define the details and dependencies together.

  • Agent development

    Scope, build, and test a custom agent with your team.

  • Models and context

    Connect models to the instructions, tools, and context required for the agent's task.

  • Access controls

    Define what the agent can read, change, and share, with permissions and review steps.

  • Custom Development

    Build the agent around the workflow and acceptance criteria agreed with your team.

  • Agent instructions and evaluation

    Define the agent's instructions, examples, and evaluation cases around the tasks it needs to handle.

  • Real-Time API and Data Integration

    Connect the agent to tools and databases through REST APIs and webhooks, with explicit data access and failure handling.

  • Built-in Commerce and Workflow Automation

    Connect sales and operational tasks through the systems and interfaces your team uses.

  • Multimodal AI (text, image, and voice)

    Configure text, image, or voice inputs where the selected model and workflow support them.

  • Cloud deployment

    Plan hosting, credentials, monitoring, and capacity around the intended usage.

  • Secure Authentication & Access Control

    Define authentication, permissions, and review steps for the data and tools used by the agent.
