## 4. Inside OpenAI's Race to Catch Up to Claude Code - WIRED

### Summary
In early 2024, Anthropic was training Claude Sonnet 3.5 on some of those messy code repositories. When the model launched that June, many users were impressed with its coding abilities. This was particularly true at a startup called Cursor, founded by a group of twentysomethings, which let developers code with AI by asking for changes in plain English. When the company incorporated Anthropic’s new model, Cursor’s usage began rocketing upward, according to a person close to the startup. Within months, Anthropic would begin internal testing of its own version: Claude Code. [...] Before Claude Code came out—first as a “limited research preview” in February 2025, then as a general release that May—the state of the art was vibe coding. People were paying hundreds of millions of dollars for tools that let a human programmer steer through a coding project while AI filled in specifics along the way. But Anthropic’s new product, like the Jam demo, worked directly from a computer’s command line, meaning it had access to all of a developer’s files and applications. This was no longer vibe coding; developers could fully offload their work to an AI agent. [...] By December 2024, several small groups inside of OpenAI were starting to focus on AI coding agents. One of them was led by Mishchenko and Thibault Sottiaux, a former Google DeepMind researcher who’s now OpenAI’s head of Codex. Initially, they were most interested in coding agents as a way to speed up AI research—automating the grunt work of managing training runs and monitoring GPU clusters. Another effort was led by Alexander Embiricos, who previously worked on OpenAI’s multimodal agents and is now the product lead for Codex. Embiricos created a demo called Jam that spread widely throughout the company.

# Inside OpenAI’s Race to Catch Up to Claude Code
Why is the biggest name in AI late to the AI coding revolution?
Photograph: MARK JAYSON QUINES
Sam Altman sits with his legs pretzeled in an office chair, staring deeply into the ceiling. To be fair, the new [OpenAI](https://www.wired.com/tag/openai/) headquarters—a temple of glass and blond wood in San Francisco’s Mission Bay—seems to invite this kind of contemplation. A kiosk behind reception holds booklets that describe the “Eras of AI” as if they were steps on the path to enlightenment. Posters along the stairs mark AI’s milestone victories, like the time thousands of humans watched on livestream as a machine beat a top-ranked esports team at *Dota 2*. In the hallways, researchers pass by in sacred merch. One shirt reads “Good research takes time.” Ideally, not too much.
[Altman](https://www.wired.com/tag/sam-altman/) and I are in an enormous conference room. The question I put to him is about the AI coding revolution—and why OpenAI doesn’t seem to be leading it. Millions of software engineers have started delegating their programming tasks to AI, forcing many in Silicon Valley to reckon with the automation of their jobs for the first time. Coding agents have emerged as one of the few areas where enterprises are willing to pay a lot for AI. This moment could, and arguably should, be the next triumphant poster along the stairs for OpenAI. But the name in big print right now belongs to someone else.
Anthropic, a smaller rival started by OpenAI defectors, has found runaway success with its programming agent, [Claude Code](https://www.wired.com/story/claude-code-success-anthropic-business-model/). The product accounts for nearly a fifth of its business—more than $2.5 billion in annualized revenue, the company said in February. By the end of January, OpenAI’s version, Codex, was bringing in just over $1 billion in annualized revenue, according to a person with direct knowledge of the matter. What gives?
“First to market is worth a lot,” Altman says finally. “We had that with ChatGPT.” But the time is right for OpenAI to lean into coding, he says. He thinks the company’s AI models are now good enough to power very capable coding agents. (Of course, the company spent billions training them to be that way.) “It's going to be a huge business—just the economic value of it, and then also the general-purpose work that coding can unlock,” Altman says. “I don't throw this around lightly, but I think it's one of these rare multitrillion-dollar markets.” What’s more, he says, Codex is “probably the most likely path” to building artificial general intelligence. By OpenAI’s definition, that’s an AI system that can outperform humans at most economically valuable work.
But while Altman makes confident pronouncements from the serenity of pretzel pose, the reality within the company over the past few years has been messier. To get the inside story, I spoke with more than 30 people, including current OpenAI leaders and employees who participated with the company’s approval and others who spoke on the condition of anonymity to discuss the inner workings of private companies. Their accounts paint a picture of OpenAI in a position it has rarely ever been in: racing to catch up.
Back in 2021, Altman and other OpenAI leaders invited WIRED journalist Steven Levy to their original office in San Francisco’s Mission district to see something new. It was an offshoot of OpenAI’s GPT-3 model, trained on billions of lines of open source code from GitHub. In a demo, executives showed how the tool, [Codex](https://www.wired.com/story/openai-copilot-autocomplete-for-code/), could take in English commands and output simple snippets of code.
"It can actually act in the computer world on your behalf," Greg Brockman, OpenAI’s president and cofounder, said at the time. "You actually have a system that can carry out commands.” Even then, OpenAI researchers thought it was obvious that Codex would be key to developing a “super assistant.”
At this time, Altman’s and Brockman’s lives revolved around meetings with Microsoft, OpenAI’s biggest investor. The software giant was tapping Codex to power one of its first commercial AI products, a code completion tool called GitHub Copilot that worked inside a programmer’s regular environment. Codex “couldn’t do much more than autocomplete” at this stage, an early OpenAI employee told me, but Microsoft executives heralded it as a sign of the AI future. When GitHub Copilot launched publicly in June 2022, it attracted hundreds of thousands of users within months.
OpenAI’s first Codex team moved on to other projects. The company planned for coding abilities to be baked into future models, the employee said, and didn’t see the need for a separate effort. Some engineers were reassigned to DALL-E 2, the company’s image generator. Others moved to train GPT-4, which was seen as the b

### Summary
Claude Code Security is intended to put this power squarely in the hands of defenders and protect code against this new category of AI-enabled attack. We’re releasing it as a limited research preview to Enterprise and Team customers, with expedited access for maintainers of open-source repositories, so we can work together to refine its capabilities and ensure it is deployed responsibly.
How Claude Code Security works
Static analysis—a widely deployed form of automated security testing—is typically rule-based, meaning it matches code against known vulnerability patterns. That catches common issues, like exposed passwords or outdated encryption, but often misses more complex vulnerabilities, like flaws in business logic or broken access control. [...] Claude’s cyberdefensive abilities have improved substantially as a result. Using Claude Opus 4.6, released earlier this month, our team found over 500 vulnerabilities in production open-source codebases—bugs that had gone undetected for decades, despite years of expert review. We’re working through triage and responsible disclosure with maintainers now, and we plan to expand our security work with the open-source community.
We also use Claude to review our own code, and we’ve found it to be extremely effective at securing Anthropic’s systems. We built Claude Code Security to make those same defensive capabilities more widely available. And since it’s built on Claude Code, teams can review findings and iterate on fixes within the tools they already use.
The road ahead [...] Rather than scanning for known patterns, Claude Code Security reads and reasons about your code the way a human security researcher would: understanding how components interact, tracing how data moves through your application, and catching complex vulnerabilities that rule-based tools miss.
Every finding goes through a multi-stage verification process before it reaches an analyst. Claude re-examines each result, attempting to prove or disprove its own findings and filter out false positives. Findings are also assigned severity ratings so teams can focus on the most important fixes first.

Making frontier cybersecurity capabilities available to defenders
=================================================================
Feb 20, 2026

**Claude Code Security**, a new capability built into Claude Code on the web, is now available in a limited research preview. It scans codebases for security vulnerabilities and suggests targeted software patches for human review, allowing teams to find and fix security issues that traditional methods often miss.
Security teams face a common challenge: too many software vulnerabilities and not enough people to address them. Existing analysis tools help, but only to a point, as they usually look for known patterns. Finding the subtle, context-dependent vulnerabilities that are often exploited by attackers requires skilled human researchers, who are dealing with ever-expanding backlogs.
AI is beginning to change that calculus. We’ve recently shown that [Claude can detect novel, high-severity vulnerabilities](https://red.anthropic.com/2026/zero-days/). But the same capabilities that help defenders find and fix vulnerabilities could help attackers exploit them.
Claude Code Security is intended to put this power squarely in the hands of defenders and protect code against this new category of AI-enabled attack. We’re releasing it as a limited research preview to Enterprise and Team customers, with expedited access for maintainers of open-source repositories, so we can work together to refine its capabilities and ensure it is deployed responsibly.
**How Claude Code Security works**
----------------------------------
Static analysis—a widely deployed form of automated security testing—is typically rule-based, meaning it matches code against known vulnerability patterns. That catches common issues, like exposed passwords or outdated encryption, but often misses more complex vulnerabilities, like flaws in business logic or broken access control.
Rather than scanning for known patterns, Claude Code Security reads and reasons about your code the way a human security researcher would: understanding how components interact, tracing how data moves through your application, and catching complex vulnerabilities that rule-based tools miss.
Every finding goes through a multi-stage verification process before it reaches an analyst. Claude re-examines each result, attempting to prove or disprove its own findings and filter out false positives. Findings are also assigned severity ratings so teams can focus on the most important fixes first.
Validated findings appear in the Claude Code Security dashboard, where teams can review them, inspect the suggested patches, and approve fixes. Because these issues often involve nuances that are difficult to assess from source code alone, Claude also provides a confidence rating for each finding. Nothing is applied without human approval: Claude Code Security identifies problems and suggests solutions, but developers always make the call.
**Using Claude for cybersecurity**
----------------------------------
Claude Code Security builds on more than a year of research into Claude’s cybersecurity capabilities. Our Frontier Red Team has been stress-testing these abilities systematically: entering Claude in [competitive Capture-the-Flag events](https://red.anthropic.com/2025/ai-for-cyber-defenders/), partnering with Pacific Northwest National Laboratory to [experiment with using AI to defend critical infrastructure](https://red.anthropic.com/2026/critical-infrastructure-defense/), and refining Claude’s ability to find and patch real vulnerabilities in code.
Claude’s cyberdefensive abilities have improved substantially as a result. Using [Claude Opus 4.6](https://www.anthropic.com/news/claude-opus-4-6), released earlier this month, our team [found over 500 vulnerabilities](https://red.anthropic.com/2026/zero-days/) in production open-source codebases—bugs that had gone undetected for decades, despite years of expert review.
