Meta Just Killed Open-Source AI
Meta has discontinued its open-source AI model Llama and replaced it with the proprietary Muse Spark, leaving startups that relied on Llama without a migration path.

Rising training costs and competitive pressures made sustaining open-source Llama economically unviable for Meta.
- ▪Meta deprecated Llama, its open-source AI model, and replaced it with the proprietary Muse Spark.
- ▪Llama had over 1 billion downloads and was widely used by startups as foundational AI infrastructure.

- ▪Muse Spark includes Shopping Mode, integrating AI-driven commerce across Meta's platforms using proprietary user data.
- ▪Startups using Llama face broken dependencies, increased costs from switching to paid APIs, and no official migration support.

If you built your company on Llama, you're now holding a dependency on abandoned infrastructure.
