Gemma 3 270M Instruct -- Lossless Compressed

512 MB - 338 MB (34% smaller). Bit-identical weights. Drop-in replacement.

Use it in 2 lines

pip install "bigsmall>=4.0"

python

from transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained("wpferrell/gemma-3-270m-it-bigsmall")

It works exactly like loading the original model. No code changes needed.

Size comparison

	Size
Original (google/gemma-3-270m-it)	512 MB
This compressed version	338 MB
Saved	174 MB (34%)

What "lossless" means

Every weight is mathematically identical to the original model.

Not quantized. Quantization rounds weights and changes model behaviour.
Not pruned. Pruning removes parts of the model.
Bit-for-bit identical. md5 is verified on every tensor at decompression.

Low-VRAM streaming

python

from bigsmall import BigSmallStreamingModel

model = BigSmallStreamingModel.from_pretrained(
    "wpferrell/gemma-3-270m-it-bigsmall",
    device="cuda",
    lru_max_vram_gb=2.0,
)

Uses up to ~12- less VRAM than standard loading by streaming layers on demand.

Stream straight from the Hub (no disk)

python

import bigsmall
state_dict = bigsmall.stream_from_hub("wpferrell/gemma-3-270m-it-bigsmall", device="cpu")

Decompresses directly from the HuggingFace CDN over HTTP range requests. With the default cache=False, no .bs file is ever written to disk (V10).

Decompress to safetensors

python

import bigsmall
from safetensors.torch import save_file

# bigsmall decompress works on local .bs files, not Hub repos, so
# stream the weights from the Hub and write them out as safetensors.
state_dict = bigsmall.stream_from_hub("wpferrell/gemma-3-270m-it-bigsmall", device="cpu")
save_file(state_dict, "gemma-3-270m-it-bigsmall.safetensors")

Original model

This is a lossless-compressed copy of google/gemma-3-270m-it. All credit to the original authors. The weights are unchanged.

Want to compress your own model?

bash

pip install "bigsmall>=4.0"
bigsmall compress my-model/ -o my-model.bs

Requires

bigsmall >= 3.14.4 for the latest features. Earlier versions (>= 3.0.0) can still decode this model.
