OpenAI's new Agents API is a hosted Codex runtime that can connect to sandboxes like E2B. OpenAI manages the model, harness, and agent sessions, while code executes on an isolated E2B machine with its own filesystem and preinstalled tools. We built an agent workbench where each chat runs on...

@OpenAI @e2b 这组合起来终于像能干活的 agent 了

@OpenAI @e2b auto-pause + fork is the important part. the durable primitive isn't a long-running machine. it's replayable task state that can hydrate into a clean machine, branch, and resume.

@OpenAI @e2b hosted harness, isolated execution — the right split

@OpenAI @e2b The way it handles orchestration and long-running sessions is actually quite impressive.

@OpenAI @e2b auto-pausing each sandbox between turns could make long agent sessions much cheaper; how quickly does a resumed machine come back?

@OpenAI @e2b The isolated filesystem plus preinstalled tools is the part that matters most in practice. Most of my agent failures used to come from environment drift, not the model. Good to see that getting solved at the infra layer instead of every project rebuilding it.

@OpenAI @e2b Auto-pause between turns is the product, not a missing automation. A hosted harness that keeps going with no human gate is just a runaway script with better branding. Forks only help if the failed branch can’t write back by default.

@OpenAI @e2b The fork is the part I'd like to see explored more. A side-by-side view of what each attempt changed would make "try another approach" much easier to judge than scrolling two chat histories.

@OpenAI @e2b how's your cold start time on spinning up a fresh e2b sandbox per session?

Gave Prime Intellect's new self-improving agent an E2B sandbox and told it to play Factorio. Factorio is a long-horizon test of world models: the agent has to learn a new system, predict the effects of its actions, and adapt when its assumptions are wrong. That requires a persistent sandbox like E2B that can keep the game running and retain its state while the agent works. Spin up a lot of sandboxes and benchmark prime agent or run your own evals with E2B. Try it yourself: e2b sbx create prime

Cursor x E2B Many of our customers use E2B in their internal development workflows. Some work in regulated industries where code and internal services can’t leave the company. For teams that need control over the execution environment, Cursor’s cloud agents can now use E2B as their machine. With Self-Hosted Machines, Cursor handles the agent loop while E2B runs the code. Teams can give agents bigger machines and start them from custom E2B templates, so their Cursor workloads boot straight into an environment with internal dependencies already in place. Try it:

How do you deploy AI agents for financial institutions without compromising on security, isolation, or scale? Rogo powers complex research, analysis, and deal workflows for leading financial firms, supporting complex tasks across tens of thousands of concurrent users. To meet the diverse needs of financial teams, Rogo relies on both specialist and general-purpose agents that can adapt to a wide range of workflows. With Claude Managed Agents and self-hosted sandboxes, Rogo gets the orchestration and post-training capabilities needed to design these agent systems, while E2B provides the execution layer underneath. Every piece of code generated by an agent runs inside its own E2B sandbox with full auditability and traceability. Each sandbox is powered by an isolated microVM, providing the kernel-level isolation critical for Rogo's customers. The result is a seamless agent experience backed by the security, reliability, and compliance requirements that financial institutions demand.

Kylon launched a new chat app with AI agents like Codex or Claude being a part of the same team. Users on the same team can link an AI agent running on their own computer and let anyone on the team @ mention it in a thread to write code or sort files. > Agents can pass the next steps of a job to a coworker after finishing their part. > Apps can be built inside the conversation, like an invoice tracker, and published to their own web address. > Each agent can keep its own memory, with the team deciding which accounts it can use.

ClickUp’s Brain² runs every frontier model with full context of your company, writing and running code to build reports, decks, and dashboards across all teams. That code touches sensitive workspace data, has to start instantly mid-conversation, and has to scale to millions of users. That’s why ClickUp built its execution layer on E2B: every sandbox is its own microVM, starts from a prebuilt template with tools ready, and scales on demand. Enterprise-ready, from SOC 2 to HIPAA to full isolation.

Waiting months for API access? Give Claude a computer instead. Use E2B with Claude's new computer and browser use toolset, and Claude gets an isolated cloud machine where every action becomes a click or keystroke. Use it to automate the work an API can't reach, like testing your own UI end to end or entering data into a legacy app. Docs: Cookbook Example:

Have you tried Gemini Managed Agents? A single API call gives you a cloud sandbox where the Antigravity agent can research, code, and complete tasks. Can try it in the Google AI Studio playground or use our SDK to build agents into your own apps. Lots more on this soon! 😀

LFG! Nous Research's Hermes Agent is live on the Umbrel App Store! It's an AI agent that gets smarter the longer it runs, remembers stuff with persistent memory across sessions, learns your workflow, and autonomously creates its own reusable skills from experience. And it's sandboxed like every Umbrel app so it can't touch anything it's not supposed to. 1-click install. Login with ChatGPT, use an OpenRouter/OpenAI/Anthropic API key, or point it to a local Ollama model running on the same Umbrel.

Just implemented Code Sandbox for TypingMind 🥳 I was looking at various options for sandbox and code execution, but for now the most obvious choice is to use the built-in sandbox provided by all popular providers: OpenAI/Gemini/Claude. It can create files but not yet able to accept file input, except for OpenAI's API, which gives your 20 minutes of "persistent container" which persist the files and the execution session. I'll look into implement 3rd party provided sandboxes like Vercel sandbox or E2B soon!

Introducing Octopus OS, a reinvented agent harness. Agents can edit their own harness in the middle of a task, on their own. Unlike Harness² and similar projects, self-improvement isn’t a separate stage bolted onto the agent. The whole architecture is just the environment they work in. Over 8 months, chasing self-improvement that feels truly native, I dropped the usual agent loop entirely and designed a new architecture that works a lot like a real operating system, with a 45k-line Rust kernel holding it all together. The system state lives in JSON files: goals act as real environments where agents work, along with inputs, outputs, and custom triggers they respond to. Agents can edit all of it while they work inside. It was also built as a product from day one, not a research demo. The full desktop app took 3 months, built on top of the Codex source. The client already works, and you can use it today like any other agent, Codex included. And it’s open source.
