Meta Platforms

Meta's AI portfolio includes assistants people use directly and model families developers can deploy. Meta AI appears in the company's assistant experiences, while Muse is a separate personal-agent product. Muse also names the model series that began with Muse Spark, so the same name can refer to the assistant or the technology behind an application. Llama is another model family, with open weights and version-specific community licenses. Those distinctions lead to different questions: an assistant needs the right product and regional access, while a model deployment needs suitable hosting and license terms. Meta AI audience figures and Llama download totals describe those different activities and should be read separately.

Products, models and their relationships

The kind labels distinguish an application or service from a model family. Availability and entitlements differ across these surfaces.
