OpenAI introduced new capabilities for its software engineering agent Codex, making it more useful beyond a developer’s laptop with reusable cloud development environments that can be accessed from any device.

The update, announced at OpenAI’s Dev Day on Tuesday, is one of several for Codex. OpenAI also announced a refreshed Codex CLI, a new code review experience, tools to harden infrastructure, and other API enhancements.

While Codex could already spin up cloud tasks to do work remotely, today’s announcement shows that OpenAI is making those cloud environments more persistent and configurable, rather than treating each cloud task as an isolated remote sandbox.

As the company explains, developers will now be able to run Codex wherever they need it, whether that’s on a computer, remotely from a phone, or in the cloud. The reusable development environments are designed to help tasks start more quickly and give teams a shared workspace with approved settings and permissions, OpenAI said.

Meanwhile, the Codex CLI is getting an update that allows developers to start and direct tasks using their voice.

A new /agents view is meant to make it easier to delegate work and track multiple tasks at the same time. Other changes include improvements to everyday tasks such as editing prompts, resuming sessions, and using worktrees. OpenAI is also rolling out a “cleaner” terminal user interface designed to make longer sessions easier to read.

Codex can also be pulled into a new code review experience within the ChatGPT desktop app, where users can read summaries, explore code changes, or ask Codex about potential issues before sharing feedback on GitHub pull requests or GitLab merge requests.

Automatic code reviews also let Codex perform an initial review while users step away from their computers.

On the security side, OpenAI is rolling out a new set of tools called Codex Security Cloud, designed to help developers secure their infrastructure. Developers can use the tools to scan entire GitHub repositories on demand or on a regular schedule, as well as whenever new commits arrive. Codex will then investigate findings, remove duplicates, and prepare fixes in the cloud — even when the user isn’t active and their laptop is closed.

Notably, the toolset includes access to the models offered through OpenAI’s cybersecurity initiative Daybreak Blue, without requiring developers to submit a separate application.

OpenAI also announced several API updates, including a new Decisions API for real-time decision-making. The API uses Luna to answer a set of user-defined questions with predefined answers. The company also introduced an updated a version of the Agents API that now supports computer use and the ability to use Amazon’s Bedrock Managed Agents to build OpenAI agents that run entirely on AWS.

OpenAI has been a close partner of Microsoft from the jump, but the AI lab is increasingly going after the company’s bread and butter, workplace software, with new features that closely resemble an office software suite like Microsoft’s.

At its Dev Day developer conference in San Francisco on Tuesday, OpenAI announced several new ChatGPT features designed for office workers.

Most notably, OpenAI launched a feature called Space, a shared workspace inside ChatGPT where coworkers can collaborate with the chatbot and with their own Dots, OpenAI’s newly launched AI agent personas (that can carry out tasks on a user’s behalf), on a range of work tasks.

“Your pages and files all live together in Space, like they would in a drive,” said CEO Sam Altman during Tuesday’s presentation. “But spaces feel alive.” Altman said users can give a page specific instructions, such as checking a team channel and updating the page with what it finds.

OpenAI also announced Pages, a companion word processor that the company describes as “a new type of document, built for human and agent collaboration.” It appears to be OpenAI’s answer to Google Docs and Microsoft Word. Users can “write, research, generate charts, create images, or visualize information” in it, OpenAI says.

OpenAI has also launched its answer to PowerPoint with what it calls collaborative slides. These slides can be created by merely talking about them within ChatGPT. Once generated, multiple workers and agents can work together within them and will have the ability to leave comments and edit them.

As OpenAI edges into the territory of Microsoft, Microsoft and other software companies like Salesforce are busy trying to become more like OpenAI. Over the past year, both companies have released a slew of AI products as the software industry attempts to keep up with the shifting landscape.

At OpenAI’s DevDay event on Tuesday, the company showed off GPT-6.1 Sol, a mere week after it launched GPT-6 Sol. OpenAI says the new model delivers nearly the same level of intelligence as GPT-6 Astra for agentic coding, computer use, and professional work, at one-fifth the standard input and output token prices.

Notably, the company is not launching GPT-6.1 Astra, as was originally expected. The Wall Street Journal reported this week that OpenAI scrapped the release over safety concerns raised by researchers during internal testing after the model showed higher levels of deception and a tendency to move forward with tasks without asking the user for permission.

OpenAI says GPT-6.1 Sol delivers significant improvements over its predecessor GPT-6 Sol across complex tasks, including programming and debugging, understanding documents, and executing multi-step workflows. The company claims that on several of these fronts, the model approaches GPT-6 Astra’s performance.

OpenAI also says the new model improves factual accuracy when given difficult prompts. Its largest gain over GPT-6 Sol on this front appears at low reasoning effort, where the share of responses containing a factual error drops from 11.4% to 7.7%. Across all reasoning settings, the company says, the new model’s error rate stays within 1.9% of GPT-6 Astra.

Additionally, the company says GPT-6.1 Sol is more upfront about its limitations and more reliable when it comes to honoring user intent and safety constraints. In challenging evaluations, it’s said to fail less often than GPT-6 Sol at flagging broken search tools, following explicit restrictions, and avoiding unauthorized outcomes during tasks. OpenAI claims it observed no attempts to circumvent the automated safety reviewer, consistent with GPT-6 Astra and GPT-6 Sol.

GPT-6.1 Sol is available starting today to all Plus, Pro, Business, Enterprise, and Edu users in ChatGPT Work and Codex. OpenAI notes that the model is not yet available in Chat.
