Mozilla released a report on the state of open-source AI arguing that open weights have become the primary route for production workloads and that the industry faces a renewed contest over control of the agentic harness layer above the model. The organization said open models are no longer a compromise and cited data showing a majority of production tokens now route through them while the five highest-volume models on OpenRouter are all open. Mozilla pointed to its 2026 developer survey with SlashData finding that 79% of developers adding AI functionality use open models compared with 71% for closed models though only 51% of open-model teams reach production versus 63% for closed teams. The report highlighted commercial traction including Databricks crossing a $5.4 billion run-rate and Mistral scaling 20 times to roughly $400 million in annual recurring revenue in twelve months. Mozilla said more than 70 national AI strategies are live and the strategic question has shifted to which layer of the stack a country can own. The organization warned that the window for ensuring open, portable and widely deployed AI is closing and called for building with communities that keep data and control with users.
