Decision models take 26% of requests; Anthropic now wins new teams 2:1

In November 2026, decision models accounted for 26% of all AI Gateway requests and 0.53% of total spend, with adoption highest among high-volume teams—70% of those processing over 10 billion tokens monthly used a decision model. Voice model usage rose 2.6 times since July, reaching 11% of paid teams. OpenAI and Anthropic now serve nearly equal shares of paid teams, but Anthropic gained more new teams (2:1), while OpenAI’s share of gateway spend increased by two-thirds since December. Over half of language-model requests went to models less than two months old, reflecting rapid model turnover with a median half-life of six weeks. In October, Anthropic’s Opus 5.5 became the top model by spend, and image and video model usage reached record levels, with OpenAI’s GPT-Image-2.5 Sunburst leading image spend and ByteDance’s Seedance 2.5 leading video spend.

Workflow SDK now writes over WebSockets on Vercel

The Vercel Workflow SDK has updated to send event writes and stream writes over WebSocket by default starting with version 5.2.0, eliminating the need for one HTTP request per write. This change improves performance, reduces costs, and enables faster AI token streaming—demonstrated by a 4.2× speed improvement in benchmarks. No code changes are required beyond upgrading to workflow@5.2.0 or later. Existing streaming code remains compatible, and in-flight workflows continue on their original deployment. Users should consult the upgrade guide if migrating from version 4.x.

Introducing Vercel Schedules

Vercel Schedules enables applications and agents to create, modify, or cancel one-time and recurring tasks dynamically through code without redeployment. It supports both static schedules defined in configuration files and dynamic schedules managed via SDK, CLI, or API during runtime. The service integrates with Vercel Queues to trigger tasks at specified times, allowing apps to handle work like data cleanup or AI-driven summaries securely and efficiently. Users can test schedules in preview environments before production, and the feature is now available in Public Beta.

Ling 3.1 Flash 1019 now available on AI Gateway for free

The Ling 3.1 Flash 1019 model from InclusionAI is now available on Vercel's AI Gateway at no cost until November 3, 2026. Designed for coding, multi-step reasoning, and tool-using agents, it features a 1M-token context window. It can be used via the model name 'inclusionai/ling-3.1-flash-1019' in applications like Claude Code, Codex, and Cursor after setting up the Vercel CLI. Free usage appears in the spend dashboard with full request tracing. After the free period, charges will apply at the published rate. AI Gateway offers unified API access, usage tracking, cost management, routing rules, and Zero Data Retention support, reflecting provider pricing without markup or platform fees.

Node.js 26 LTS is now Generally Available on Vercel

Node.js 26 LTS is now generally available for builds and Vercel Functions, featuring HTTP/2 by default in fetch (Undici 8), the Temporal API for immutable time handling, and V8 14.6 with new JavaScript features like Map.prototype.getOrInsert(). It is the default for new projects, with automatic upgrades for compatible package.json engines.node versions and manual upgrade options via package.json or Vercel CLI 65.8.0+. HTTP/1.1 can be retained by setting VERCEL_FETCH_DISABLE_H2 to 1. Minor and patch updates are applied automatically.

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.
