gemma-3-270m-gguf

This repository contains GGUF-formatted, quantized versions of Gemma 3 270M (base model), prepared and published by Open4Bits for efficient local inference on low-resource systems.

Open4Bits is a model distribution and optimization initiative under ArkAI Labs, which is run and operated by ArkDevLabs. Through Open4Bits, ArkAI Labs publishes quantized, optimized, and deployment-ready models in GGUF and other inference-friendly formats.


About Open4Bits

gemma-3-270m-Q8_0.gguf Q8_0 Near-baseline quality (reference)

Recommended Variants

  • Q4_K_M โ€“ Recommended for most users (best balance of quality, speed, and memory)
  • Q5_K_M โ€“ Higher quality for users who can afford additional memory usage
  • Q8_0 โ€“ Near-baseline reference for evaluation and comparison

Quantization Overview

IQ4 Variants

  • Extremely small and fast
  • Suitable for very limited hardware
  • Noticeable quality reduction compared to K-quant variants

Q4_0 / Q4_1

  • Older quantization formats
  • Included for compatibility and comparison
  • Generally inferior to modern K-quant variants

K-Quant Variants (Q4_K_S, Q4_K_M, Q5_K_S, Q5_K_M)

  • Newer, higher-quality quantization methods
  • Better accuracy per bit
  • Standard choice for GGUF deployments

Q8_0

  • Near-baseline (FP16-like) quality
  • Highest memory usage among provided variants
  • Intended for reference, testing, and debugging

Usage with llama.cpp

./main -m gemma-3-270m-Q4_K_M.gguf \
  -p "Explain what GGUF quantization is." \
  -n 128

Usage with Ollama

Create a Modelfile:

FROM ./gemma-3-270m-Q4_K_M.gguf

Then run:

ollama create gemma-270m -f Modelfile
ollama run gemma-270m

System Requirements (Approximate)

Quantization Memory Requirement
IQ4_NL / IQ4_XS ~300โ€“400 MB
Q4_0 / Q4_1 ~450โ€“500 MB
Q4_K_S ~500 MB
Q4_K_M ~550โ€“600 MB
Q5_K_S ~600โ€“650 MB
Q5_K_M ~650โ€“750 MB
Q8_0 ~900 MB โ€“ 1 GB

Actual memory usage depends on context length and runtime configuration.


Intended Use and Limitations

This model is a small, lightweight base language model optimized for low-resource inference.
