Qwen 2.5 Max is the flagship Mixture-of-Experts (MoE) AI of Alibaba designed to compete with industry-leading systems such as GPT‑4o, Claude 3.5
Introduction
Qwen 2.5 Max is meant to straddle performance and efficiency. Based on MoE architecture, it employs specialist “experts” instantiated per task to trade off computation load and intelligence. The model performs its best benchmark performance without showing an explicit reasoning trace, providing results that are intuitive and highly aligned.
Available through Qwen Chat or as an API with OpenAI-compatible endpoints, Qwen 2.5 Max is intended to be simple to use and integrate. Users can try it for free on the web, then scale to heavier usage through Alibaba Cloud’s pay-as-you-go infrastructure.

Getting started with: step by step guide
Getting started with Qwen is easy:
Step 1: Visit Qwen Chat
Access Qwen Chat via your browser and choose “Qwen 2.5 Max” from the model dropdown. Chat for free to begin exploration.
Step 2: Register Alibaba Cloud & Enable Model Studio
Sign up for an Alibaba Cloud account, enable Model Studio, and create your API key.
Step 3: Integrate via OpenAI-Compatible API
Utilize provided endpoints (e.g., model name “qwen‑max‑2025‑01‑25”) with your key in your current OpenAI-compatible codebase.
Step 4: Adjust Parameters
Tweak temperature, max_tokens, and other parameters to adjust output quality and style.
Step 5: Track Usage & Scale
Track usage and spend using Alibaba’s console. Scale when production workloads are ready.
Frequently Asked Questions
Q: Is it open-source?
A: No, Qwen 2.5 Max is proprietary. Alibaba has open weights planned but hasn’t published them yet.
Q: Can I fine-tune it?
A: No, only available through API; no local fine-tuning or weight adjustment.
Q: How much context can it process?
A: Up to 128K tokens per session.
Pricing
Qwen 2.5 Max can be accessed using pay-as-you-go API on Alibaba Cloud. Reportedly, users find it costs about one-tenth the price of GPT‑4 pricing per equivalent usage.
