Qwen 3.5 Plus is now available on AI Gateway.

The model comes with a 1M context window and built-in adaptive tool use. Qwen 3.5 Plus excels at agentic workflows, thinking, searching, and using tools across multimodal contexts, making it well-suited for web development, frontend tasks, and turning instructions into working code. Compared to Qwen 3 VL, it delivers stronger performance in scientific problem solving and visual reasoning tasks.

To use this model, set model to alibaba/qwen3.5-plus in the AI SDK:

import { streamText } from 'ai';
const result = streamText({
  model: 'alibaba/qwen3.5-plus',
  prompt:
    `Analyze this UI mockup, extract the design system,
     and generate a production-ready React component
     with responsive breakpoints and theme support.`,
});

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.
