Rather than spinning up isolated remote sandboxes, Codex now offers persistent, configurable cloud environments with shared team settings. The Codex CLI gains voice controls, a new /agents view for tracking multiple tasks, prompt editing improvements, worktree support, and a cleaner terminal UI. A new code review experience in the ChatGPT desktop app lets users read summaries and ask Codex about issues before commenting on GitHub or GitLab. Codex Security Cloud can scan repositories on schedule or on new commits, investigate findings, and prepare fixes autonomously, with access to models from OpenAI's Daybreak Blue cybersecurity initiative. New API updates include a Decisions API powered by Luna, an updated Agents API with computer use support, and integration with Amazon Bedrock Managed Agents for running OpenAI agents on AWS. ## Full article daily.dev links to this article rather than hosting it.

Codex now supports reusable, persistent cloud development environments that work across devices, including computers, phones, or fully in the cloud, rather than spinning up a fresh isolated sandbox for every task. These environments start tasks faster and give teams a shared workspace with pre-approved settings and permissions. _Developers tracking new agent capabilities like this can follow Codex updates on daily.dev._ ### What does Codex Security Cloud do? Codex Security Cloud scans entire GitHub repositories on demand, on a schedule, or whenever new commits arrive, then investigates findings, removes duplicates, and prepares fixes in the cloud even while the developer's laptop is closed. It also includes access to models from OpenAI's Daybreak Blue cybersecurity initiative without a separate application. _Teams evaluating automated security scanning tools can keep up with releases like this via daily.dev._ ### What can developers do with the new Codex code review experience in ChatGPT? Within the ChatGPT desktop app, developers can read summaries of code changes, explore diffs, and ask Codex about potential issues before leaving feedback on GitHub pull requests or GitLab merge requests. Codex can also run an automatic initial review while the developer is away from their computer. _Developers comparing AI code review workflows can track tools like this through daily.dev._ ## Similar posts on daily.dev - [OpenAI announces Codex for mobile devices](https://daily.dev/posts/openai-announces-codex-for-mobile-devices-xwxibqwio) · SD Times · 0 upvotes · 0 comments - [OpenAI says Codex is coming to your phone](https://daily.dev/posts/openai-says-codex-is-coming-to-your-phone-c24qjzdpe) · TechCrunch · 2 upvotes · 0 comments - [OpenAI brings Codex to the ChatGPT mobile app](https://daily.dev/posts/openai-brings-codex-to-the-chatgpt-mobile-app-usgk8lgxx) · The New Stack · 0 upvotes · 0 comments --- Tags: [#ai-agents](https://daily.dev/tags/ai-agents), [#openai](https://daily.dev/tags/openai), [#code-review](https://daily.dev/tags/code-review), [#appsec](https://daily.dev/tags/appsec), [#openai-codex](https://daily.dev/tags/openai-codex) [View this post on daily.dev](https://daily.dev/posts/openai-gives-codex-reusable-cloud-environments-that-work-across-devices-hrcoiqfqh) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"OpenAI gives Codex reusable cloud environments that work across devices","url":"https://daily.dev/posts/openai-gives-codex-reusable-cloud-environments-that-work-across-devices-hrcoiqfqh","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/openai-gives-codex-reusable-cloud-environments-that-work-across-devices-hrcoiqfqh"},"datePublished":"2026-09-29T17:19:11.602Z","dateModified":"2026-09-29T23:48:03.269Z","description":"OpenAI expanded Codex, its software engineering agent, with reusable cloud development environments accessible across devices, announced at OpenAI's Dev Day....","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/cf5d97abae5414d1e1911e4d527c6b6d?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/cf5d97abae5414d1e1911e4d527c6b6d?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"TechCrunch","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"TechCrunch","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/tc","url":"https://daily.dev/sources/tc"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/openai-gives-codex-reusable-cloud-environments-that-work-across-devices-hrcoiqfqh","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"ai-agents,openai,code-review,appsec,openai-codex","timeRequired":"PT3M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"TechCrunch","item":"https://daily.dev/sources/tc"},{"@type":"ListItem","position":3,"name":"OpenAI gives Codex reusable cloud environments that work across devices"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/openai-gives-codex-reusable-cloud-environments-that-work-across-devices-hrcoiqfqh#faq","mainEntity":[{"@type":"Question","name":"What new features did OpenAI add to Codex for cloud development environments?","acceptedAnswer":{"@type":"Answer","text":"Codex now supports reusable, persistent cloud development environments that work across devices, including computers, phones, or fully in the cloud, rather than spinning up a fresh isolated sandbox for every task.
