- What it is
- Apple's June 2025 research post, updated July 17, 2025, on the foundation language models behind Apple Intelligence. It describes a compact on-device model and a larger server model, and points to the 2025 technical report.
- How much weight it carries
- Apple's own research post, written by the team that built the models, so it is a primary source for the model's design. It describes the model family, not which apps or features use it. It gives the model size as approximately 3 billion parameters, without the exact count.
Facts taken from this source
- Apple's 2025 foundation models update describes a compact on-device model of approximately 3 billion parameters, optimized to run efficiently on Apple silicon.
“optimized to run efficiently on Apple silicon, and include a compact, approximately 3-billion-parameter model, alongside a mixture-of-experts server-based model” (Introduction)
