Rapid42/gemma-4-E2B-it-MLX

Gemma 4 (~1B, E2B ultra-efficient variant) — MLX format for Apple Silicon, instruction-tuned

Converted and optimized by Rapid42 — engineering tools for fast pipelines.

What This Is

This is Gemma 4 E2B — Google DeepMind's ultra-compact multimodal Gemma 4 variant (~1B parameters) in MLX format for native Apple Silicon inference. Instruction-tuned (-it) for chat and task-following.

The E2B is the smallest model in the Gemma 4 family — prioritising speed and minimal memory over raw capability. It still supports image input, making it the most capable sub-2B multimodal model available in MLX format.

• Parameters: ~1B (E2B = Efficient 2B-class, actual ~1B)
• Modality: Text + Image input → Text output
• Format: MLX (Apple Silicon native)
• Base model: google/gemma-4-it
• License: Apache 2.0

Hardware Requirements

Device	RAM	Experience
Any M-series Mac (8GB+)	~1.5GB	✅ Runs on everything
M1 MacBook Air (8GB)	~1.5GB	✅ Extremely fast
iPhone / iPad (via MLX)	~1.5GB	✅ On-device capable
M3 Max	~1.5GB	✅ Near-instant — alongside any other app

The lightest multimodal model you can run locally. Load time under 2 seconds.

Quick Start

pip install mlx-lm

Text chat:

from mlx_lm import load, generate

model, tokenizer = load("Rapid42/gemma-4-E2B-it-MLX")

messages = [{"role": "user", "content": "Summarize this in one paragraph: [paste text]"}]
prompt = tokenizer.apply_chat_template(
    messages, add_generation_prompt=True, return_dict=False
)

response = generate(model, tokenizer, prompt=prompt, max_tokens=256, verbose=True)
print(response)

CLI (fastest way to chat):

mlx_lm.chat --model Rapid42/gemma-4-E2B-it-MLX

With image input (via MLX-VLM):

pip install mlx-vlm
python -m mlx_vlm.generate \
  --model Rapid42/gemma-4-E2B-it-MLX \
  --prompt "What's in this image?" \
  --image /path/to/image.jpg

E2B vs E4B — Which to Use?

Use Case	E2B (~1B)	E4B (~8B)
Quick summaries, short answers	✅ Fast	✅ More accurate
Complex reasoning	❌ Limited	✅ Much better
Always-on background assistant	✅ Ideal	⚠️ Uses more RAM
Image understanding	✅ Basic	✅ Strong
On-device mobile	✅ Yes	⚠️ Tight
Code generation	⚠️ Simple only	✅ Good

Rule of thumb: Use E2B when you need speed and low overhead. Use E4B when you need quality.
