Gemma 4 E2B IT — Hardware Requirements & GPU Compatibility

ChatFunctions

The smallest model discussed here from Google's Gemma 4 E-series, Gemma 4 E2B IT, comes in at roughly 5 billion parameters. It is tuned for chat and instruction-following rather than multimodal tasks, prioritizing a minimal footprint over broad input support. Models at this size are comfortable on typical consumer GPUs, and can even run on integrated graphics when quantized aggressively, making it one of the more accessible options for local deployment. It ships with a 128K token context window, matching its larger E4B sibling, and is released under the Apache 2.0 license for open commercial and research use. Google published it on March 2, 2026, alongside the E4B variant, as the entry point into the Gemma 4 generation.

Run Gemma 4 E2B IT

3.5 GB VRAM at 16K context · fits the RTX 4090 (20.5 GB free)

Works on macOS, Windows and Linux.

Install Ollama (Linux)
$curl -fsSL https://ollama.com/install.sh | sh
Install Ollama (macOS / Windows)
Download and run the app; it installs the ollama command.
Download Ollama ↗
Run Q4_K_M
$ollama run hf.co/unsloth/gemma-4-E2B-it-GGUF:Q4_K_M
Raise the context window
Type it inside the chat. For the API server instead, start it with OLLAMA_CONTEXT_LENGTH=16384 ollama serve.
$/set parameter num_ctx 16384
A larger context needs more memory than the weights alone.
Use the API
Ollama serves its API on http://localhost:11434.

Works on macOS, Windows and Linux.

Install LM Studio
Desktop app for macOS (Apple silicon), Windows and Linux.
lmstudio.ai ↗
Download the model
In the app press Ctrl/Cmd + Shift + M and search google/gemma-4-e2b, then pick Q4_K_M. Or use the CLI (run LM Studio once first):
$lms get google/gemma-4-e2b@q4_k_m
Open on Hugging Face ↗
Load and chat
Open the model loader, select the model and set Context Length to 16384. Leave GPU offload at maximum if it fits.
Start the local server (optional)
$lms server start

Works on macOS, Windows and Linux.

Install llama.cpp (macOS)
MacPorts, Nix and conda-forge also work.
$brew install llama.cpp
Install options ↗
Install llama.cpp (Windows)
$winget install llama.cpp
Install llama.cpp (Linux)
Download the prebuilt llama-*-bin-ubuntu-* archive for your GPU backend (CPU, Vulkan) from the releases page, unpack it and run the binaries from that folder. Homebrew (brew install llama.cpp) and conda-forge also work on Linux.
llama.cpp releases ↗
Start the server
Downloads the model on first run. The chat UI and an OpenAI-compatible API are at http://localhost:8080.

Frequently Asked Questions

How much VRAM does Gemma 4 E2B IT need?

Gemma 4 E2B IT requires 3.4 GB of VRAM at Q4_K_M, or 10.6 GB at BF16. Full 131K context adds up to 0.7 GB (4.1 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 5.1B × 4.8 bits ÷ 8 = 3.1 GB

KV Cache + Overhead ≈ 0.3 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 1 GB (at full 131K context)

Can I run Gemma 4 E2B IT on a Mac?

Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Gemma 4 E2B IT. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 3.4 GB of usable unified memory (RAM minus macOS overhead).

Can I run Gemma 4 E2B IT locally?

Yes — Gemma 4 E2B IT can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Gemma 4 E2B IT?

At Q4_K_M, Gemma 4 E2B IT can reach ~1399 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~191 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: NVIDIA B200 → 8000 ÷ 3.43 × 0.65 = ~1516 tok/s
