VERCEL

Vercel Labs' fx installs as a 7.8 MiB Zig binary and runs as a shell-like CLI, a JSON script endpoint, an ACP server, or an embeddable WebAssembly module. Here is the verified setup path, the three auth routes, and the workflows each surface unlocks.

fx is Vercel Labs' experimental coding agent written in Zig: a roughly 6 MiB native binary built to be embedded anywhere from CI sandboxes to the browser. We read the source, the docs, and the launch thread so you can decide fast.

Two minimal coding agents are taking swings at the platform era, but they minimize opposite things: pi refuses features, fx shrinks the bytes. Placing both on the harness spectrum against Claude Code and raw shells shows who each bet is actually for.

Vercel Sandbox now polices all outbound traffic on the host, outside the microVM, with SNI-based domain policies, CIDR rules, host-level credential injection, and a deny-all default. Here is why a network boundary is the half of agent isolation that VM escapes missed.

Vercel added Hermes Agent to AI Gateway and made Vercel Sandbox a terminal backend for the open-source agent. Hermes is now fully BYO: your own model routing through 200+ models at no markup, and your own cloud microVM for every agent command. Here is what that unlocks and why the agent control plane is consolidating.

skills.sh now lets you bundle multiple agent skills into a shareable, unlisted pack and install it with one command. Packs mix public directory skills, private local files, and GitHub repos, then sync with a single update command. Here is how they work, what they mean for team standardization, and where the trust questions are.

Vercel, OpenAI, GitHub, Microsoft, AWS, and Cursor collaborated on Agent Plugins 1.0.0, an open standard that packages Agent Skills and MCP servers into one portable plugin. ChatGPT, Codex, Cursor, GitHub Copilot, Kiro, and VS Code load the format on day one.

Vercel's Chat SDK can now suspend a Workflow SDK run until someone clicks Approve in a chat thread. One requestApproval call replaces the approvals table, the onAction handler, and the polling loop - with verified decisions, scoped approvers, and a wait that survives deploys.

DeepSeek V4 Flash routed to Novita on Vercel AI Gateway is 90% off for Pro customers through August 11, dropping the effective rate to $0.014 input / $0.028 output per million tokens. Here is the verified before/after math, the provider-pinning setup, and what a 10x cheap agent loop means for routing decisions.

Next.js 16.3 ships the biggest update since 16.0: opt-in Instant Navigations with partial prefetching, up to 90% less dev-server RAM, cached repeat builds up to 5.5x faster, native Node.js streams for SSR, and an AGENTS.md block that points coding agents at version-matched docs.

The v0 API is now generally available: programmatic, headless access to v0's app-building agent. Send a prompt, get a running app with a live preview URL you can embed, then deploy to Vercel in one call. Here is what changed, how the sync/async/streaming model works, and how it fits in an agent loop.

Self-improving applications shift the economics of maintenance. Instead of per-token pricing, you pay per closed issue - and the closed loop (user feedback to GitHub issue to Codex scheduled task to reviewed PR) means the cost is predictable, the fixes are testable, and the human is in the merge decision, not the implementation.

AI Gateway spend budgets now scope to teams and projects, with hard dollar limits that reject requests, email alerts at 50/75/100%, and CLI-managed defaults. Here is how the three scopes compose and where it fits your cost stack.

Vercel MCP now serves both the stateless 2026-07-28 protocol and the 2025 protocol from one endpoint, with mcp-handler 2.x handling the negotiation. The first major hosted MCP server has crossed over - here is what it means for server authors and clients.

Vercel cut end-to-end deployment time by up to 7 seconds, removing 5 seconds of fixed platform overhead from every build and up to 2 more seconds from the CLI path. Here is exactly where the time went and what it means for your CI loop.

Vercel Passport is generally available: protect deployments behind Okta, Entra ID, or any OIDC provider, and read a verified identity in app code with getIdentity(). Here is how it works and why it matters.

Vercel Labs released Scriptc, a TypeScript-to-native compiler that produces self-contained binaries of 170-200KB with ~2ms startup times and no embedded JavaScript engine. The HN community is sharply divided on whether this is a genuine engineering breakthrough or another Vercel Labs project that will be abandoned in months.

Vercel acquires the open-source authentication framework that became the go-to Next.js auth solution. HN weighs in on open source sustainability and vendor lock-in concerns.

A companion guide to the Agents 101 video: a behind-the-scenes walkthrough of building and deploying AI agents fast on Vercel, the agentic infrastructure stack. Here is the map of what to learn and where to go next.

Vercel's eve gives you the agent plumbing - durable sessions, sandboxed code execution, approvals, subagents - as a folder of files. Fable 5 gives you a long-horizon reasoning model. Here is how to wire them together, what it costs, and who the stack fits.
