Who should use this model?

  • Structured extraction, tool routing, and lightweight on-device agent components.

Choose something else when

  • You need advanced reasoning, code generation, or creative writing.

What hardware makes sense?

The download is only part of the memory needed. Leave room for the app, the input it processes, and other open programs. For chat models, context includes the instructions, conversation, and answer. Longer context needs more memory.
