Durable Agents and Workflows

Restate automatically handles the reliability challenges of AI agents: Durable AI Agent Execution
  • Automatically retry transient errors like rate limits and network failures
  • Persist steps (LLM calls, tools) and recover previous progress after failures
  • Suspend long-running agents when idle to save costs
Restate works independently of any SDK and specific AI stack, but its lightweight programming abstraction integrates easily into many popular SDKs. A few lines turn your agent into a durable agent. 
const model = wrapLanguageModel({
  model: openai("gpt-4o"),
  middleware: durableCalls(restateContext, { maxRetryAttempts: 3 }),
});
Works with Vercel AI SDK, OpenAI, and others.

Human-in-the-Loop and Workflow Patterns

Restate’s workflows-as-code and building blocks make it easy to reliably implement:

Human Approval

Durable waiting for human decisions with crash-proof timeouts

Parallelization

Speed up multi-step workflows with recoverable parallel tasks

Sub-workflows

Break complex agents into smaller, specialized workflows

Multi-agent Orchestration

Coordinate specialized agents with reliable communication

Compensation Patterns

Automatically undo previous actions when later steps fail

Interruptible Agents

Build agents that can be paused, modified, and resumed during execution

​
Observability and Debugging

See all ongoing executions with detailed journals of agent steps:
AI Agent Execution Trace
  • Complete execution timeline: Every LLM call and tool execution
  • Debug failed agents: Inspect exactly where and why agents failed
  • Agent control: Pause, resume, restart agents during development and production

​
End-to-End Resilient Applications

Agents are just a part of your application. Restate covers the plumbing around your agents:
Application Structure
  • Queuing, state, session management: Built-in primitives for reliable agent coordination
  • Deterministic workflows: Complement agents with structured business logic
  • Reliable asynchronous tasks: Handle background work and inter-service communication

​
Flexible Deployments and Scalability

Restate’s durable execution runtime lets you run your durable code where you want at the scale you want: Application Structure
  • Scale to millions of concurrent agent executions
  • Deploy your agents on FaaS or containers
  • You own the infrastructure: Run on Restate Cloud or self-host
