Memory planning

16GB RAM estimate

Expected pace

Depends on your hardware, app, and conversation length

License

Apache-2.0; read the model’s terms before use

Who should use this model?

  • Apache-2.0 12B local assistant
  • long-context local use up to 128k when memory permits
  • coding and world-knowledge tasks in the 12B class
  • drop-in upgrade path from Mistral 7B-class systems

Choose something else when

  • you only have 8 GB RAM
  • you need a tiny edge model
  • you need supported explicit tool-call support from the fetched model card

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.

CPU only
A possible starting point with a compressed model and short conversation; check the exact file size.
8GB system memory
Use a smaller model for this memory limit.
16GB system memory
A possible starting point with a compressed model and short conversation; check the exact file size.
32GB system memory
A possible starting point with a compressed model and short conversation; check the exact file size.
8GB GPU memory
Memory or response time may limit use. Try a smaller model first.
12GB GPU memory
A possible starting point with a compressed model and short conversation; check the exact file size.
24GB GPU memory
A possible starting point with a compressed model and short conversation; check the exact file size.
Apple unified memory
Comfortable on 16GB or more unified memory

Conditions that change the answer

  • Memory needs include the model file, the app, and conversation memory. Longer conversations and other open apps need more space.
  • Check that this exact model can use your app’s connected tools before relying on that feature.
  • Language coverage is not confirmed in the available model information. Test a representative prompt in the language you need before choosing this model.
