Mozilla's 2026 Open-Source AI Report Shows Chinese Models Dominating OpenRouter

The Mozilla Foundation's State of Open Source AI report is a key gauge of global developments in artificial intelligence. As the performance gap between open and closed models continues to narrow, open-source AI has become critical for companies seeking to lower technical barriers and development costs. The report highlights a shift in the global technology landscape, particularly in how developers use open platforms to access high-performance, low-cost models. This shift has far-reaching implications for the pace of innovation and competition across the technology industry.

The Mozilla Foundation's latest report, published in 2026, said AI inference costs had fallen 50-fold over the past three years. Against this backdrop, China's open-source ecosystem has expanded rapidly, with Chinese models accounting for as much as 61% of traffic on the open-source API platform OpenRouter. Qwen and DeepSeek are the most popular, indicating that Chinese technology has established a dominant position in the global open-source sector.
