Key takeaways

• Qwen is now the most-downloaded AI model family on Earth.
• Built by Chinese AI lab; open weights; quietly outpacing Western alternatives by adoption volume.
• Part of the broader shift: open-source models (Qwen, Gemma 4) are catching up to closed-source models for specific use cases.

Why it matters for Harris

• Gemma 4 (April 2026 release) gets a lot of attention for being Apache 2.0 — but Qwen has been eating market share quietly for months.
• Evaluation point: if Harris considers open-weights alternatives for regulated customers, Qwen and Gemma 4 are both on the table.
• Regulatory consideration: Chinese AI model may face different compliance questions than Western-origin models in some verticals (public sector, defence, certain financial scenarios).
