Qwen3 Max
VerifiedQwen3 Max tackles long-context text tasks with an open-weight design.
About Qwen3 Max
Qwen3 Max follows the transformer architecture typical of modern LLMs and is distributed with open weights for local or cloud deployment. Its 262144-token context window enables processing of lengthy inputs without truncation in many scenarios. The model accepts only text modality and carries no disclosed parameter count.
Strengths center on sustained coherence across very long sequences and flexible fine-tuning by the open-source community. Users benefit from its availability without licensing fees tied to closed models. It avoids reliance on proprietary APIs for core inference.
Typical usage includes document analysis, multi-turn dialogue systems, and code repositories that exceed standard context limits. Researchers often deploy it for experiments requiring full context retention. Integration occurs via standard frameworks that support open-weight checkpoints.

Quick start
OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. Only the model slug changes between models.
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://openrouter.ai/api/v1",
apiKey: process.env.OPENROUTER_API_KEY,
});
const completion = await client.chat.completions.create({
model: "qwen/qwen3-max",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: qwen/qwen3-max
