## Overview

Qwen2.5-Max is the flagship model of Alibaba's Qwen2.5 generation, unveiled on January 29, 2025. It is a large-scale Mixture-of-Experts (MoE) model pretrained on more than 20 trillion tokens and post-trained with supervised fine-tuning and RLHF. Unlike the open-weight Qwen2.5 dense models (0.5B to 72B, released under Apache 2.0), Qwen2.5-Max was kept proprietary and offered only through Alibaba Cloud's API and the Qwen Chat web app.

The launch landed in the middle of the DeepSeek V3 moment, and Alibaba positioned Qwen2.5-Max directly against it. On the chat-instruct benchmarks Alibaba published, Qwen2.5-Max edged out DeepSeek V3 on Arena-Hard, LiveBench, LiveCodeBench, and GPQA-Diamond, and traded blows with GPT-4o and Claude 3.5 Sonnet on knowledge tasks like MMLU-Pro. It was, for a window in early 2025, one of the strongest non-reasoning Chinese models available.

Today Qwen2.5-Max is a historical checkpoint rather than Alibaba's headline model. Its API snapshot, qwen-max-2025-01-25, remains reachable through Alibaba Cloud Model Studio and resellers such as OpenRouter, but Alibaba's flagship line has since moved on through the Qwen3 and Qwen3-Max generations. Treat it as a capable, mid-2020s general-purpose chat model that has been superseded.

## Benchmarks

- Arena-Hard: 89.4% ([source](https://qwenlm.github.io/blog/qwen2.5-max/))
- MMLU-Pro: 76.1% ([source](https://qwenlm.github.io/blog/qwen2.5-max/))
- GPQA-Diamond: 60.1% ([source](https://qwenlm.github.io/blog/qwen2.5-max/))
- LiveCodeBench: 38.7% ([source](https://qwenlm.github.io/blog/qwen2.5-max/))
- LiveBench: 62.2% ([source](https://qwenlm.github.io/blog/qwen2.5-max/))

## Pricing

- Input: $1.60 / 1M tokens per 1M tokens (USD, international qwen-max)
- Output: $6.40 / 1M tokens per 1M tokens (USD, international qwen-max)

Pricing for the international qwen-max deployment on Alibaba Cloud Model Studio. Mainland China deployment of the qwen-max-2025-01-25 snapshot is billed in RMB at lower equivalent rates.

## Strengths

- Strong instruction-following and chat quality for its era — led DeepSeek V3 on Arena-Hard (89.4 vs 85.5)
- Competitive general knowledge and reasoning, scoring 76.1 on MMLU-Pro, close to GPT-4o and Claude 3.5 Sonnet
- Solid multilingual coverage, including strong Chinese-language performance, from 20T+ token pretraining
- Mixture-of-Experts architecture delivers flagship-tier quality with efficient per-token inference
- OpenAI-compatible API on Alibaba Cloud makes it a low-friction drop-in for existing tooling

## Best for

- General-purpose chat assistants and Q&A in English and Chinese
- Multilingual content generation, summarization, and rewriting
- Code generation and completion for everyday programming tasks
- Knowledge-heavy reasoning and analysis at non-reasoning-model latency
- A China-region alternative to GPT-4o-class proprietary APIs

## FAQ

### Is Qwen2.5-Max open source?

No. Qwen2.5-Max is proprietary and closed-weight, available only through Alibaba Cloud's API and the Qwen Chat app. This differs from the smaller Qwen2.5 dense models (0.5B-72B), which Alibaba released as open weights under the Apache 2.0 license.

### How does Qwen2.5-Max compare to DeepSeek V3?

On the chat-instruct benchmarks Alibaba published, Qwen2.5-Max edged out DeepSeek V3 on Arena-Hard (89.4 vs 85.5), LiveBench (62.2 vs 60.5), LiveCodeBench (38.7 vs 37.6), GPQA-Diamond (60.1 vs 59.1), and MMLU-Pro (76.1 vs 75.9). The two were close competitors in early 2025.

### How much does the Qwen2.5-Max API cost?

On the international Alibaba Cloud Model Studio deployment, qwen-max is priced at $1.60 per 1M input tokens and $6.40 per 1M output tokens. The mainland China deployment of the qwen-max-2025-01-25 snapshot is billed in RMB at lower equivalent rates.

### Is Qwen2.5-Max still Alibaba's best model?

No. The qwen-max-2025-01-25 snapshot is still reachable via API, but Alibaba's flagship line has since advanced through the Qwen3 and Qwen3-Max generations, which outperform it. Qwen2.5-Max is now best treated as a superseded checkpoint.
