Libraries

How to use wyattearp/Gemma-4-E4B-text-base with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="wyattearp/Gemma-4-E4B-text-base")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForCausalLM

processor = AutoProcessor.from_pretrained("wyattearp/Gemma-4-E4B-text-base")
model = AutoModelForCausalLM.from_pretrained("wyattearp/Gemma-4-E4B-text-base", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Google Gemma-4-E4B-text-base (Modality-Stripped Text Backbone)

Gemma-4-E4B-text-base is a clean, text-only extraction of Google's Gemma-4-E4B-it instruction-tuned model. By decoupling and stripping multimodal projections (vision and audio towers), this checkpoint provides a pure language model backbone optimized for text, software engineering, and tool-calling deployments.

⚡ Why Modality-Stripped?

Standard Gemma-4 checkpoints integrate multimodal encoders and cross-attention projectors. For dedicated text generation, reasoning, and coding agent workloads:

VRAM Reduction: Saves memory otherwise reserved for vision transformer buffers and projector parameters.
Simplified Inference: Eliminates multimodal input pre-processing overhead and dependencies in downstream serving engines (vLLM, TensorRT-LLM, llama.cpp).
Pristine Weight Fidelity: The underlying text transformer parameters (model.language_model.*) are 100% identical bit-for-bit to the upstream release.

🔬 Model Profile

Parameter Count: $\sim 4.2\text{B}$ parameters.
Context Length: 131,072 tokens.
Format: Standard Hugging Face safetensors compatible with transformers >= 4.40.0.
Vocabulary Size: 256,000 tokens.

⚠️ Important: Tool-Calling Parser Bugfix in vLLM

Upstream Bug Report: vllm-project/vllm#54256
Official Pull Request: vllm-project/vllm#54257 — [Bugfix][Parser] Support bare call: and whitespace-free channel transitions in Gemma4 parser
