    GPT 5.1 Codex Max now available on Vercel AI Gateway

    OpenAI debuts GPT-5.1 Codex Max with Vercel AI Gateway, enabling multi-context long-running coding tasks and faster, token-efficient performance. The AI Gateway offers unified API, observability, BYOK, retry and routing for higher uptime.

    GPT-5.1 Codex Max with OpenAI AI Gateway

    You can now access OpenAI's latest Codex models, GPT-5.1 Codex Max with Vercel's AI Gateway and no other provider accounts required.

    Using a process called compaction, GPT-5.1 Codex Max has been trained to operate across multiple context windows and on real-world software engineering tasks. GPT-5.1 Codex Max is faster and more token efficient compared to previous Codex models, optimized for long-running coding tasks, and can maintain context and reasoning over long periods without needing to start new sessions.

    To use GPT-5.1 Codex Max with the AI SDK, set the model to openai/gpt-5.1-codex-max.

    AI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime. It includes built-in observability, Bring Your Own Key support, and intelligent provider routing with automatic retries.

    Rewrites and redirects now available in runtime logs

    Runtime Logs

    Vercel users can now view requests that make rewrites or redirects directly in the Vercel dashboard in runtime logs.

    By default, these requests are filtered out on the Runtime Logs page. To view these requests on the Logs page, you can filter for Rewrites or Redirects in the Resource dropdown.

    • Rewrites: shows the destination of the rewrite
    • Redirects: shows the redirect status code and location

    This feature is available to all users. Try it out or learn more about runtime logs.

    Vercel

    Introducing Vercel for Platforms

    Vercel launches Vercel for Platforms with Multi-Tenant and Multi-Project modes to build and run customer apps at scale. It supports single codebase or per-customer projects, wildcard and custom domains, edge routing, and SDK domain management, plus Platform Elements and Quickstart.

    You can now build platforms with the new Vercel for Platforms product announced today, making it easy to create and run customer projects on behalf of your users.
    Two platform modes are available: Multi-Tenant and Multi-Project, allowing you to deploy with a single codebase or many, across any number of domains.

    Multi-Tenant Platforms

    Run a single codebase that serves many customers with:

    • Wildcard domains (*.yourapp.com) with automatic routing and SSL.
    • Custom domain support via SDK, including DNS verification and certificate management.
    • Routing Middleware for hostname parsing and customer resolution at the edge.
    • Single deployment model: deploy once, changes apply to all tenants.

    Add custom domains to your app in seconds:

    import {
      addDomain,
      getDomainStatus,
    } from "@/components/vercel-platform/src/actions/add-custom-domain";
    const added = await addDomain("test.com");
    if (added.status === "Valid Configuration") {
      // do something
    }
    const config = await getDomainStatus("test.com");
    config.dnsRecordsToSet;
    // show this in a table
    

    Multi-Project Platforms

    Create a separate Vercel project per customer with:

    • Programmatic project creation with the Vercel SDK.
    • Isolation of builds, functions, environment variables, and settings per customer.
    • Support for different frameworks per project.

    Deploy your customer's code into isolated projects in seconds:

    import {
      deployFiles
    } from "@/components/vercel-platform/actions/deploy-files";
    // automatically detects the framework & build commands
    await deployFiles([], {
      // optionally assign a custom domian
      domain: "site.myapp.com",
    });
    

    Today we are also introducing Platform Elements, a new library to make building on platforms easier.
    Start building with our Quickstart for Multi-Tenant or Multi-Project platform.

    New deployments of vulnerable Next.js applications are now blocked by default

    Any new deployment containing a version of Next.js that is vulnerable to CVE-2025-66478 will now automatically fail to deploy on Vercel.

    We strongly recommend upgrading to a patched version regardless of your hosting provider. Learn more

    This automatic protection can be disabled by setting the DANGEROUSLY_DEPLOY_VULNERABLE_CVE_2025_66478=1 environment variable on your Vercel project. Learn more

    Domains must now be managed at the team level

    Managing domains at the account level

    Managing domains at the account level is no longer supported. Domains must now be managed at the team level, which simplifies access control, collaboration, and unified billing.

    Domains that are currently linked to accounts will continue to resolve, serve traffic, and renew as usual, but any changes will require moving the domain to a team.

    When viewing an account-level domain, you'll now be prompted to select a destination team to transfer your domain and all project domains, DNS records, and aliases will move to that team and continue to work after the move.

    Next.js by Vercel

    Security Advisory: CVE-2025-66478

    A critical vulnerability (CVSS 10.0) has been identified in the React Server Components protocol that can allow remote code execution. All Next.js 15.x and 16.x users should upgrade immediately.

    Summary of CVE-2025-55182

    A critical vulnerability in React Server Components may allow remote code execution. Vercel deployed automatic protections and partners issued mitigations; users should upgrade to patched versions. Updated React and Next.js releases include fixes across affected packages.

    Summary

    A critical-severity vulnerability in React Server Components (CVE-2025-55182) affects React 19 and frameworks that use it, including Next.js (CVE-2025-66478). Under certain conditions, specially crafted requests could lead to unintended remote code execution.

    We created new rules to address this vulnerability and quickly deployed to the Vercel WAF to automatically protect all projects hosted on Vercel at no cost. We also worked with the React team to deliver recommendations to the largest WAF and CDN providers.

    We still strongly recommend upgrading to a patched version regardless of your hosting provider.

    Impact

    Applications using affected versions of the React Server Components implementation may process untrusted input in a way that allows an attacker to perform remote code execution. The vulnerability is present in versions 19.0, 19.1.0, 19.1.1, and 19.2.0 of the following packages: :

    • react-server-dom-parcel (19.0.0, 19.1.0, 19.1.1, and 19.2.0)
    • react-server-dom-webpack (19.0.0, 19.1.0, 19.1.1, and 19.2.0)
    • react-server-dom-turbopack (19.0.0, 19.1.0, 19.1.1, and 19.2.0)

    These packages are included in the following frameworks and bundlers:

    • Next.js with versions 6430.3.0-canary.77, 6415 and 6416
    • Other frameworks and plugins that embed or depend on React Server Components implementation (e.g., Vite, Parcel, React Router, RedwoodSDK, Waku)

    Resolution

    After creating mitigations to address this vulnerability, we deployed them across our globally-distributed platform to quickly protect our customers. We still recommend upgrading to the latest patched version.

    Updated releases of React and affected downstream frameworks include hardened handling of user inputs to prevent unintended behavior. All users should upgrade to a patched version as soon as possible. If you are on Next.js 14.3.0-canary.77 or a later canary release, downgrade to the latest stable 14.x release.

    • Fixed in:
      • React: 19.0.1, 19.1.2, 19.2.1
      • Next.js: 15.0.5, 15.1.9, 15.2.6, 15.3.6, 15.4.8, 15.5.7, 16.0.7

    Frameworks and bundlers using the aforementioned packages should install the latest versions provided by their respective maintainers.
