    OpenAI is building its own GitHub alternative

    OpenAI is reportedly developing an in-house alternative to Microsoft-owned GitHub, partly triggered by recent GitHub outages and designed to host agent-driven development like Codex. The project remains in its early stages and months away, but OpenAI has discussed eventually opening the platform to customers. Why it matters: Owning the repo layer lets OpenAI deeply integrate AI engineering loops—while stepping directly onto its biggest partner’s turf.

    OpenAI open-sources Symphony to run coding agents from your project board

    OpenAI just open-sourced Symphony, an orchestration tool that turns Linear boards into autonomous agent workflows. Instead of supervising coding models line by line, teams assign issues and let Symphony dispatch isolated Codex runs that implement features, pass CI, and record video walkthroughs for human sign-off. It shifts developer focus from watching agents code to managing the actual work.

    OpenAI and Figma just bridged code and design

    OpenAI and Figma just rolled out a new Codex-to-Figma integration powered by the Figma MCP Server. Teams can now turn Figma canvases into working code and reverse code back into editable Figma designs across Design, Make, and FigJam. Why it matters: It turns product development into a seamless roundtrip, letting engineers design and designers build without switching contexts.

    OpenAI built an invisible credit engine so Sora and Codex never stop

    OpenAI just detailed a custom real-time access engine for Codex and Sora that stops rate limits from cutting off user momentum. Instead of hitting a hard wall when allowances run out, requests seamlessly tap into pre-purchased credits mid-flight. Why it matters: By combining instant limits with provably auditable async billing, OpenAI keeps creators and coders in their flow without the risk of double-charging.

    OpenAI rolls out ultra-fast Codex-Spark for real-time coding

    OpenAI just launched GPT-5.3-Codex-Spark, a lightweight coding model powered by Cerebras chips that outputs over 1,000 tokens per second. Built for instantaneous, interactive edits rather than autonomous background tasks, it cuts roundtrip latency by up to 80%. ChatGPT Pro users can take it for a spin today inside Codex and VS Code.

    OpenAI introduces GPT-5.3-Codex: 25% faster and helped build itself

    OpenAI just launched GPT-5.3-Codex, an agentic model that is 25% faster and sets high marks on SWE-Bench Pro. Remarkably, the Codex team used early versions of the model to debug its own training run and manage deployment. It turns coding into an interactive, real-time collaboration that spans the entire software lifecycle.

    Sam Altman calls Anthropic's Super Bowl ad "clearly dishonest"

    Sam Altman just slammed Anthropic's new Super Bowl ad on X, calling it "clearly dishonest" for attacking theoretical ad formats OpenAI would never run. Altman argued OpenAI is committed to broad free access—claiming more Texans use ChatGPT for free than total US Claude users—while branding Anthropic as an expensive, "authoritarian" company trying to control what people build.

    OpenAI turns Codex into a command center for AI agents

    OpenAI just launched the Codex desktop app for macOS (now on Windows too), moving beyond a single coding companion to a command center for managing teams of parallel agents. Built-in git worktrees keep agents from colliding, while custom skills let them design, test, and deploy. Rate limits are temporarily doubled for paid tiers, and free users get a taste too.

    OpenAI launches GPT-5.2-Codex for heavy-duty coding and security

    OpenAI just rolled out GPT-5.2-Codex, an agentic coding model tuned for complex software engineering and defensive cybersecurity. It brings native context compaction for massive refactors, better Windows support, and sharper security auditing chops. It is available now in Codex for paid ChatGPT users, with API access rolling out soon.

    OpenAI drops GPT-5.1-Codex-Max for marathon coding

    OpenAI just launched GPT-5.1-Codex-Max, an agentic coding model built to run continuously for over 24 hours. Using native context compaction, it works seamlessly across multiple windows on multi-million-token refactors while cutting thinking tokens by 30%. It is now the default engine inside Codex.

    OpenAI takes on prompt injection attacks

    OpenAI just detailed its multi-layered strategy to defend AI agents against prompt injection attacks. As autonomous models browse the web and handle sensitive data, hidden malicious instructions inside web pages or emails pose serious security risks. OpenAI is deploying instruction hierarchy training, automated monitors, sandboxing, and sensitive-action confirmations. Why it matters: Preventing agents from going off-script is the prerequisite for letting AI handle real-world work.

    OpenAI Codex goes GA with Slack bot and new SDK

    OpenAI just made its Codex AI coding agent generally available, rolling out a direct Slack integration, enterprise admin tools, and a TypeScript SDK. Engineering teams can now delegate code tasks by tagging @Codex in Slack threads or embed the agent directly into custom CI/CD pipelines. Codex daily usage has already surged over 10x since August.

    OpenAI upgrades Codex for autonomous coding

    OpenAI just overhauled Codex with a specialized model fine-tuned for real-world software engineering. The agent dynamically adjusts its thinking time, can run autonomously for over seven hours on massive refactors, and automatically reviews GitHub PRs for bugs. Why it matters: AI coding is shifting from line-by-line autocomplete into an independent teammate that tackles complex tasks end-to-end.

    OpenAI's Codex CLI is already open-source

    OpenAI reminded developers that its Codex CLI coding agent is already fully open-source under the Apache-2.0 license. The lightweight tool runs locally in terminal environments across macOS, Linux, and Windows, integrating with IDEs like VS Code and Cursor. Why it matters: users can run local terminal coding agents powered directly by their ChatGPT plans without waiting on closed releases.

    Former OpenAI engineer reveals how 17 people built Codex in 7 weeks

    Former OpenAI engineer Calvin French-Owen just dropped a candid look inside the AI giant, detailing how a tiny 17-person team pulled seven sleepless weeks to launch the Codex coding agent. The company tripled to 3,000 employees in one year, running largely on Slack with messy monolithic code and early-Facebook 'move fast' energy.

    OpenAI drops Codex, an autonomous agent that codes in the cloud

    OpenAI just launched Codex, a cloud-based software engineering agent powered by codex-1, a specialized version of o3. It operates inside isolated cloud sandboxes to write features, execute test suites, and open GitHub PRs across multiple tasks in parallel. Why it matters: Developers can now offload entire background engineering workflows asynchronously rather than babysitting real-time completions.

    OpenAI hires an army of contractors to teach AI how to code

    OpenAI just recruited roughly 1,000 remote contractors in regions like Latin America and Eastern Europe, with about 40% tasked with writing step-by-step coding explanations to train its models. Rather than scraping raw GitHub code, the company is capturing human reasoning and debugging workflows. Why it matters: Teaching models human thought processes could soon automate entry-level software development entirely.
