Did Huawei’s Pangu AI Model Copy Alibaba’s Qwen? Untangling the Controversy and What It Means for the Future of Chinese AI

In the ever-evolving world of artificial intelligence, few stories generate as much buzz—and confusion—as allegations of copying or “upcycling” between tech giants. This week, all eyes are on Huawei after its AI lab publicly denied claims that its latest Pangu Pro Moe model was copied from Alibaba’s Qwen 2.5. If you’re following China’s surging AI scene, you know how high the stakes are—not just for these companies, but for the entire industry.

So, what’s really going on here? Is this a tempest in a teapot, or a sign of deeper challenges in rapid AI development? Let’s break it down, get to the heart of the controversy, and figure out why this matters far beyond just Huawei and Alibaba.

The Background: Why the Huawei vs. Alibaba AI Debate Has Everyone Talking

Before diving into the details, let’s set the stage. Chinese AI firms are in an unprecedented arms race, building ever more capable large language models (LLMs) to rival global leaders like OpenAI and Google. In this high-stakes environment, even a whiff of plagiarism can spark major debate.

Here’s the quick version:

Huawei’s Pangu Models: Initially released in 2021, Huawei’s Pangu family is aimed at enterprise and government users. Recently, it open-sourced Pangu Pro Moe—the latest iteration—hoping to boost adoption by letting developers tinker freely.
Alibaba’s Qwen Family: Qwen 2.5-14B, released in May 2024, is part of Alibaba’s versatile Qwen lineup. Known for consumer-facing AI like chatbots, Qwen’s adaptability lets it run on everything from PCs to smartphones.

The twist: An anonymous group named HonestAGI posted a technical analysis on GitHub, claiming Huawei’s Pangu Pro Moe showed “extraordinary correlation” with Alibaba’s Qwen 2.5 14B—suggesting Huawei didn’t build from scratch, but “upcycled” Qwen’s work.

The Accusation: Did Huawei Copy Alibaba’s AI Model?

Let’s get specific. HonestAGI’s paper alleges that Huawei’s Pangu Pro Moe model:

Has code or weights strikingly similar to Alibaba’s Qwen 2.5-14B.
May not have been trained from the ground up, but rather adapted or “upcycled” from Qwen.
Possibly violates copyrights, misrepresents technical details, and overstates Huawei’s own training investments.

You might be wondering: How do researchers even detect these correlations?

Here’s how it works: – AI models, especially language models, can be compared by analyzing their outputs to identical inputs, examining internal weight structures, or evaluating performance on benchmarks. – If two models trained independently are too similar, it raises eyebrows—especially if their “learning fingerprints” match at a granular level.

But correlation doesn’t always mean causation. Models trained on similar data, using related architectures, may naturally converge in some respects. The line between inspiration and imitation is often blurry, especially in the open-source era.

Huawei Responds: The Noah Ark Lab Statement

The day after HonestAGI’s claims went viral, Huawei’s Noah Ark Lab fired back with a firm denial:

“The model was not based on incremental training of other manufacturers’ models. We made key innovations in architecture design and technical features.”

The lab emphasized: – Independent development and training: No incremental building on Qwen or any other closed-source model. – Originality: “Key innovations” in architecture and technical features. – Hardware: Pangu Pro Moe is the first large-scale model built entirely on Huawei’s Ascend chips—a move aimed at reducing reliance on Nvidia and U.S. technologies. – Open-source compliance: The team adhered to license requirements for any third-party code, but didn’t specify which open-source projects influenced Pangu.

Notably, Alibaba has not commented publicly, and HonestAGI’s identity remains unknown. This ambiguity only adds fuel to the speculation.

Understanding the Stakes: Why AI Model Provenance Matters

You might ask: Why does it matter if one AI model was “inspired by” or “built from” another? Here’s why this controversy means more than just bragging rights:

1. Intellectual Property and Copyright

AI models are valuable IP. Copying without permission can lead to lawsuits, reputational damage, and lost business.
Open-source licenses (like Apache, MIT, or GNU) may allow certain uses, but require proper attribution or prohibit commercial reuse.

2. Trust and Innovation

The AI community thrives on trust—transparency about model origins, training data, and architecture.
If a leading player is caught “upcycling” instead of innovating, it undermines confidence in reported breakthroughs.

3. Geopolitical Competition

China’s AI race is partly about technological self-reliance, especially under U.S. export restrictions (Reuters).
Demonstrating genuine innovation—especially on homegrown chips—matters for national pride and global credibility.

The Open-Source Factor: Collaboration or Copycat?

Here’s where it gets tricky. The AI world is increasingly open-sourced:

Open Weight Models: Many AI companies (including Meta and Google) release models under permissive licenses, inviting others to build, adapt, and remix their work.
Shared Ecosystem: Improvements to language models often build on public research, datasets, and codebases.

But: Not all “open” models are equal. Some licenses restrict commercial use, require attribution, or ban derivative works. If Huawei did use Qwen’s open-source code, compliance with these terms is crucial—not optional.

Let me explain: Imagine a chef using someone else’s recipe. If it’s an open-source recipe, you’re allowed to riff on it, but you need to credit the original author and follow any restrictions. Hiding that would be like entering a cooking contest with someone else’s secret sauce.

How Similar are Pangu and Qwen… Really?

Technical observers have pointed out:

Both Pangu Pro Moe and Qwen 2.5-14B are “Mixture of Experts” models—a cutting-edge technique that routes input to specialized sub-networks, making the model more efficient.
Their training data and architectures may have overlap, given the shared tech ecosystem in China.

However, the devil is in the details. Even with similar blueprints, execution can vary wildly:

Training from scratch (on raw data, with original code) is costly, but maximizes ownership.
Fine-tuning an existing model is faster and cheaper, but raises questions about originality.

Without full transparency from both companies, it’s nearly impossible for outsiders to conclusively say how much, if any, code was reused. HonestAGI’s analysis offers compelling data, but it’s not a legal verdict.

Huawei’s Position in the Chinese AI Landscape

To understand the broader context, let’s zoom out.

Huawei: Early Mover, Playing Catch-Up?

Pangu’s first release in 2021 was a breakthrough, especially for Chinese-language processing in government and industry.
But as Alibaba, Baidu, and startups like DeepSeek (whose surprisingly cheap R1 rocked Silicon Valley) accelerated, Huawei was seen as lagging.
Open-sourcing Pangu Pro Moe in June 2024 was a bid to regain developer mindshare and spark innovation on Huawei’s Ascend chip platform.

Alibaba: The Consumer-Facing Giant

Qwen 2.5-14B is designed for broad deployment—PCs, smartphones, and cloud chatbots, reminiscent of OpenAI’s ChatGPT.
Alibaba’s deep pockets and cloud infrastructure give Qwen a natural boost in consumer and commercial sectors.

Here’s why that matters: In China’s hyper-competitive AI market, perception of originality and technical leadership is just as important as raw performance.

Global Repercussions: Why This Story Resonates Beyond China

The Huawei-Alibaba drama isn’t just an internal squabble. Here’s why the world is watching:

Open-Source AI Risks: The ease of “remixing” models puts open-source innovation at risk if boundaries aren’t respected (MIT Technology Review).
Corporate Transparency: Tech users—governments, businesses, consumers—need to trust that their AI isn’t a legal minefield.
R&D Incentives: If original builders aren’t credited or compensated, it could discourage new breakthroughs.

What Comes Next? Potential Outcomes and Industry Lessons

With Alibaba silent and HonestAGI anonymous, what can we expect?

Potential Scenarios: – Clarification and Audit: Huawei may disclose more technical details or even invite a third-party audit to prove independent development. – Legal Action: If evidence mounts, Alibaba could pursue legal remedies, though that’s rare in China’s tech landscape. – Industry Standards: This case may accelerate calls for clearer AI provenance standards, especially for large language models.

If you’re a developer or business evaluating AI models, here’s what to watch: – Check documentation: Does the model clearly state its origins and training data? – Review licenses: Are you comfortable with the model’s legal terms, especially for commercial use? – Assess transparency: Is the team responsive to scrutiny and open about technical details?

Key Takeaways: What We’ve Learned from the Huawei vs. Alibaba AI Model Dispute

Allegations of AI “copying” are tricky—similar outputs don’t always prove malfeasance, especially in open-source ecosystems.
Huawei’s Noah Ark Lab categorically denies building on Alibaba’s Qwen 2.5-14B, emphasizing independent architecture and hardware innovation.
The real challenge for China (and the global AI community) is setting clearer standards for transparency, attribution, and IP respect.
For businesses and developers, due diligence on model origins is more important than ever.

Bottom line: This story isn’t just about Huawei or Alibaba. It’s a sign of the growing pains in AI’s open-source revolution—where the line between inspiration and imitation is still being drawn.

FAQ: People Also Ask

Did Huawei really copy Alibaba’s Qwen AI model?

As of now, there’s no public, legally verified evidence that Huawei copied Alibaba’s Qwen model. While HonestAGI’s analysis suggests strong similarities, Huawei categorically denies these claims, asserting independent development.
