Building AI agent demos is easy. Building a suite of agents that are reliable and securely connected across environments is the hard part.

Over the past few years, Scale has helped the world’s largest enterprises bring AI into complex workflows. We’ve learned that the biggest challenges aren’t about what agents can do, but how they run. As teams adopt AI, they naturally build agents in different ways, which is okay. The real challenge is connecting them, keeping them reliable, and deploying them securely in production. The more agents you build, the harder they are to manage.

We set out to fix this problem, and that’s why we’re open-sourcing Agentex: the agentic infrastructure layer inside the Scale GenAI Platform. Agentex is an enterprise-grade framework for building, deploying, and managing AI agents. It gives developers a standard way to host and orchestrate long-running, asynchronous agents at scale. And now, we’re making it available to everyone.

Introducing Agentex

We sat down as a team to demo Agentex and discuss how it’s used across our enterprise customers today. We also talk about our decision to open-source and how we hope to collaborate with the community. Watch our conversation below.

Why Agentex?

Most agents built today focus on relatively simple behaviors: they answer a question, use a tool, and exit. They’re often single-turn reasoning or limited tool use in response to a prompt. These are valuable but incomplete. In real-world environments, agents need to do much more than respond once and exit.

Think about insurance claims processing. An agent today might be prompted by a claims agent to review a document, analyze its contents, and return a policy summary. But a truly transformational agentic system is autonomous and continuously monitors new submissions, automatically processes claims as they arrive, and orchestrates other agents or systems (software, databases, or even humans) to complete each case. It can wait indefinitely for a response and resume seamlessly from where it left off.

These kinds of always-on, persistent agents unlock transformational enterprise applications across industries. We built Agentex to enable these types of agentic applications.

Inside Agentex

See developer docs here.

Under the hood, Agentex handles async and long-running processes, multi-agent communication, persistent state and logs, and durable workflows through deep integration with Temporal.

It includes a Python SDK to define agent behavior, a CLI for scaffolding and managing agents, a backend Agent Server for running agents locally or in production, and a developer UI to test, debug, and observe them. The framework is Docker and Kubernetes native. This lets teams build agents that stay running, coordinate with other systems, and reliably recover if interrupted.

You can start with a single local agent on your laptop, or scale up to a suite of agents communicating across a production environment.

Python SDK

Defines how agents are structured and run

CLI

Scaffolds, runs, and manages agents

Agent Server

Backend runtime that hosts agents locally or in production

Developer UI

Frontend to test, debug, and monitor agents

Docker + Kubernetes native

Runs locally or deploys to any cloud environment

Durable Workflows

Ensures agents can pause, resume, and recover seamlessly using persistent state and workflow durability

Agent Communication

Enables agents to message, coordinate, and trigger one another across distributed systems

Long-Running Processes

Supports asynchronous, always-on agents that can wait for events, external inputs, or human actions before continuing

Why We’re Open-Sourcing

Every enterprise we work with builds AI agents differently. There wasn’t an open, vendor-agnostic framework that could support those variations while remaining lightweight, secure, and inspectable. So we built one.

By open-sourcing Agentex, we’re making enterprise-grade agentic infrastructure accessible to all developers. Whether you’re experimenting locally or managing a portfolio of live agents, Agentex provides a shared, flexible foundation to build on.

Open-source also ensures transparency and community evolution. We want developers to see how these systems work under the hood, extend them freely, and help define what “production-grade” agentic systems look like. We believe Agentex will become the standard layer for hosting and orchestrating agents, enabling developers to build freely while giving enterprises the control and reliability they need for production systems.

Agentex is for Individual Developers and Enterprise Teams

For individual developers, Agentex offers an easy on-ramp to building agents. You can scaffold, run, and observe your agent locally in minutes with a familiar Python-first experience. These capabilities are open-source.

For enterprise teams, Agentex powers a managed, zero-ops deployment layer as part of the Scale GenAI Platform. This includes CI/CD automation, authentication (SSO/SAML), compliance, and full lifecycle management. This enables your teams to focus on business logic rather than infrastructure.

Here’s a quick guide to the difference between the open-source and enterprise editions.
