SETUP HINTS
OLLAMA
ollama run gemma2:27bLM 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.QUANTIZATION FILE SIZES (GGUF)

Hardware fit values are conservative local-inference estimates based on GGUF size plus runtime and KV-cache overhead. Actual requirements depend on context length, quantization, runtime, GPU offload, and other running apps.
BEST FOR
·higher-quality local chat
·summarization
·drafting
·workstation inference
AVOID IF
·image input is required
·less than 32GB system RAM is available
·native tool/function calling is required
CAVEATS
·Gemma 2 is text-only; do not treat it as a vision-language model.
·GGUF files are community conversions, not official Google GGUF releases.
·RAM and VRAM figures are estimates based on GGUF file size plus conservative runtime and KV-cache overhead, not official hardware requirements.
