Model Serving AI Agents Platform Coding Assistant Data Analysis

About

E2B is an open-source runtime for executing AI-generated code in secure cloud sandboxes. Made for agentic & AI use cases. We built E2B with the next generation of developers in mind — software engineering AI agents. Sandboxes are powered by Firecracker microVM, a VM made for running untrusted code. The E2B Sandboxes in the same region as the client start in less than 200 ms. Each E2B sandbox can run up to 24 hours. Deploy E2B in your AWS, or GCP account and run sandboxes in your VPC.

Features & Capabilities

—Securely execute AI-generated code in cloud sandboxes.
—Supports various programming languages and frameworks.
—Provides features tailored for LLM-powered development, including code execution context control, error inspection, package installation, and interactive charts.
—Offers up to 24-hour long sandbox sessions (Pro plan).
—Allows for custom sandbox template creation and package installation during runtime.

Use Cases

Task Automation

Handle multi-step workflows autonomously

Example

Schedule meeting → Find time → Send invite → Confirm attendees

✓

Save 5-10 hours/week on routine coordination tasks

Information Synthesis

Gather data from multiple sources and summarize

Example

Research competitor pricing across 5 websites, create comparison table

✓

Reduce research time from hours to minutes

Decision Support

Analyze options and recommend actions

Example

Review 20 vendor proposals, score against criteria, rank top 3

✓

Make data-driven decisions faster

Architecture

AI agents combine large language models with tools, memory, and decision-making logic to autonomously complete multi-step tasks without constant human guidance.

LLM Core

Large language model for reasoning and decision-making

Understand tasks, plan steps, generate responses

Tool Integration

APIs, databases, external services the agent can call

Take actions beyond text generation (search, compute, write files)

Memory System

Short-term (conversation) and long-term (persistent) memory

Maintain context across interactions and learn from past actions

Orchestration Logic

Decision engine for choosing next action

Plan multi-step workflows and handle errors/edge cases

Implementation Guide

Prerequisites

›Clear task definition and success criteria
›APIs and tools agent will need to access
›Approval workflows for sensitive actions
›Monitoring and logging infrastructure

Steps

1Define agent scope and capabilities
2Integrate necessary tools and APIs
3Build orchestration logic for task planning
4Test with low-risk tasks in sandbox
5Monitor performance and iterate

Best Practices

✓ Do

+Start with narrow, well-defined tasks
+Monitor agent actions and outcomes
+Provide human oversight for critical decisions
+Iterate based on real-world performance
+Measure ROI: time saved, errors reduced, costs

✗ Don't

−Don't deploy without testing edge cases
−Don't give agent access to sensitive systems without safeguards
−Don't ignore agent errors—investigate and fix root cause
−Don't scale before proving value on pilot tasks

Performance & Optimization

Key Metrics

Task completion rate: % of tasks agent completes successfully
Time to completion: Agent vs. human baseline
Error rate: % of tasks requiring human intervention
Cost per task: LLM costs vs. human labor savings

Optimization Tips

→Cache common workflows to reduce redundant LLM calls
→Fine-tune decision logic based on failure patterns
→Expand tool library to handle more use cases
→Implement human-in-loop for high-stakes decisions
