Expected pace

Depends on your hardware, app, and conversation length

License

Gemma Terms of Use; read the model’s terms before use

Who should use this model?

  • higher-quality local chat
  • summarization
  • drafting
  • workstation inference

Choose something else when

  • image input is required
  • less than 32GB system RAM is available
  • native tool/function calling is required

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.

First setup

Ollama

ollama run gemma2:27b

LM Studio: Search for bartowski/gemma-2-27b-it-GGUF and select Q4_K_M or Q5_K_M.

llama.cpp

Use hf.co/bartowski/gemma-2-27b-it-GGUF:Q4_K_M; increase context only if memory permits.

Conditions that change the answer

  • Gemma 2 is text-only; do not treat it as a vision-language model.
  • GGUF files are community conversions, not official Google GGUF releases.
  • Allow memory for the model file, the app, and your conversation.
