Qwen3.5 27B

by Alibaba

All Alibaba releases

Qwen3.5-27B is a 27 billion parameter multimodal model that blends vision and language through early fusion training on multimodal tokens, built on a hybrid architecture of Gated DeltaNet and Mixture-of-Experts layers. It supports a 262,144 token native context window, extensible toward roughly one million tokens with YaRN scaling. Reported scores include MMLU-Pro 86.1, GPQA Diamond 85.5, SWE-bench Verified 72.4, and MathVista 86.0, reflecting balanced strength across reasoning, coding, and visual understanding. It runs in thinking mode by default, generating reasoning before responses. The model handles text, image, and video inputs across more than 200 languages, suiting knowledge-intensive problems, agentic coding, and multimodal reasoning.

Get started

Call Qwen3.5 27B through the qynio gateway with one API key. Let your coding agent set it up, or call it directly β€” qynio is drop-in compatible with the OpenAI, Anthropic, and Google AI SDKs.

Set it up with your agent

Copy this and paste it into a coding agent like Claude Code, Cursor or Codex and it'll wire up qynio for you.

Or call it directly

import OpenAI from "openai";
const client = new OpenAI({
apiKey: process.env.QYN_API_KEY,
baseURL: "https://api.qyn.io/v3/compat",
});
const completion = await client.chat.completions.create({
model: "deepinfra/Qwen/Qwen3.5-27B",
messages: [{ role: "user", content: "Hello" }],
});
console.log(completion.choices[0].message.content);
