How OpenEvidence scales medical search for 650K doctors

OpenEvidence, a platform helping physicians access peer-reviewed medical evidence at the point of care, leverages Vercel to deploy updates in minutes, handle traffic spikes without additional provisioning, and reduce serverless costs by 90% through Fluid compute. The platform supports over 20 million clinical consultations monthly and serves more than 100 million Americans annually, with its small engineering team managing independent deployments for doctor- and patient-facing applications using Next.js and Vercel's infrastructure.

How Zapier turns ideas into working software in hours with Vercel

Zapier leverages Vercel to rapidly develop interactive partner demos in under two hours, build internal applications like Marketing Hive and Marketing OS in a day each, and securely share sensitive data through SSO-protected deployments. The platform enables non-developers to deploy applications, supports AI orchestration via AI Gateway, and facilitates scalable, secure code execution with 3.3 million sandboxes created monthly. Vercel's speed, security, and ease of use have become central to Zapier’s innovation across engineering, marketing, and sales teams.

Tencent Hy4 now available on AI Gateway

Hy4, Tencent's latest AI model with vision capabilities, is now available on Vercel's AI Gateway at 50% off through December 31, 2026. It supports reasoning, tool calling, structured outputs, image input, and a 1M-token context window. Hy4 excels in detailed image analysis, complex chart reading, and computer use across command-line and graphical interfaces. It outperforms its preview version in instruction following, long-context handling, and deep research tasks. Users can access it via the model name 'tencent/hy4' in supported tools like Claude Code, Codex, and Cursor after setting up the Vercel CLI. AI Gateway offers unified API access, usage tracking, cost management, and performance optimizations with no markup or platform fees.

Vercel MCP now renders deployments as an interactive card

Vercel MCP introduces an interactive card feature for ChatGPT and compatible chat clients, displaying live deployment status, build logs, source details, and a Visit button upon completion. Users can debug via logs shared in chat or view full logs in fullscreen mode. For repositories with multiple projects, a project selector is available. The feature leverages the MCP Apps extension, with fallback text-only display for unsupported clients. The open_deployments tool enables lookups by project, repository, or commit with environment filtering, accessible through ChatGPT's Connectors setup.

Vercel MCP now supports Client ID Metadata Documents

Vercel MCP now allows any client to connect by publishing a Client ID Metadata Document (CIMD), eliminating the need for manual review. Clients use a JSON file's HTTPS URL as their OAuth client_id, with consent screens displaying the client's name, logo, and hostname for transparency. Verified badges are not granted to CIMD clients, so users must trust the hostname when approving access. Existing registered apps remain unaffected.

Blocking malicious npm packages before and during installation

Vercel now proactively checks for and blocks malicious npm packages before and during dependency installation in builds using a dynamic blocklist, preventing harmful scripts from executing. The system scans supported lockfiles and public npm downloads, automatically failing deployments if a blocked package is detected, identifying the problematic package and version, and attempting to invalidate the build cache. Users must update to a safe dependency version and regenerate the lockfile before redeploying. These security measures apply automatically to all plans without requiring configuration.

Introducing Vercel Security Review

Vercel introduces Security Review, a new feature in Vercel Agent that automatically scans for vulnerabilities in code changes pushed to connected GitHub repositories. It provides real-time findings via pull request comments, a Security dashboard, and CLI access, with options to auto-fix issues using Vercel Agent or integrate with custom coding agents. The tool checks for logic flaws, enforces team-specific security policies, tracks vulnerabilities across deployments, and supports audit logging for Enterprise users. Available now in public beta for Pro and Enterprise teams, it is free until November 10, 2026.

Data Cache is moving to Runtime Cache

Data Cache is being phased out and replaced by Runtime Cache in Next.js, with automatic migration for all versions. Pro teams receive 8x more storage per project, while Enterprise projects get 10x their previous allocation. Post-migration, previously unbilled reads and writes will be charged at $0.40 per million read units and $4.00 per million write units, varying by region. Hobby teams receive 1 million free read and 200,000 free write units monthly. Pro teams use a $20 infrastructure credit before billing applies. Teams created on or after October 30, 2026, will default to Runtime Cache. Migration dates: November 29, 2026 for Hobby; Pro and Enterprise teams will be notified separately. Early opt-in is available starting October 30, 2026, with immediate pricing application. Teams can disable caching in CDN settings without affecting migration. Optimization guidance is available via Observability and the Vercel Agent.

Introducing Geist Serif

Vercel has launched Geist Serif, a high-contrast display serif typeface designed as part of the Geist family, which includes Geist Sans, Geist Mono, and Geist Pixel. Built on the same foundational principles as its predecessors, Geist Serif features fine serifs, sharp hairlines, and a variable axis called Element Shape (ELSH) offering four dot variants: Regular, Square, Triangle, and Heart. It maintains consistent x-height and cap height with Geist Sans for seamless integration across layouts. The font supports 352 Latin-script languages, includes 894 glyphs, and is available via npm and Vercel’s font platform. Future updates will include additional weights, an italic variant, Cyrillic support, and availability on Google Fonts. The release marks a shift toward editorial and fashion-inspired design, honoring print traditions while leveraging modern screen capabilities.

Simplifying runtime caching on Vercel

Vercel is merging its Data Cache service into Runtime Cache, unifying data caching across frameworks like Next.js, SvelteKit, and Nuxt. Developers using fetch caching or unstable_cache in Next.js won’t need to change their code. Pro and Enterprise projects receive increased storage allocations, with Pro getting 8x more space and Enterprise 10x. Runtime Cache now handles regional storage, authentication, and tag-based invalidation across Vercel’s global infrastructure. Improvements include faster reads during traffic bursts via circuit breakers, higher storage budgets reducing evictions, and enhanced observability with deployment markers, revalidation causes, and write utilization metrics. The migration simplifies billing and usage tools, with existing teams receiving advance notice and pricing details.

Vercel Flags starts 7x faster and no longer extends function duration

The Vercel Flags SDK has been updated to initialize 7x faster on cold starts by loading and parsing the flags datafile at client creation and checking for updates without a network request. Usage reporting now no longer extends function duration, as events are passed directly to the Vercel runtime. Update to version 1.5.3 or later to benefit from these improvements.
