What is new in Gemma 4

Google DeepMind shipped Gemma 4 in April 2026 as a four-tier family: two compact edge models (E2B, E4B) tuned for laptops and 12 GB consumer GPUs, a 26B-parameter Mixture-of-Experts variant with 4B active parameters (A4B) targeting mid-range desktops, and a 31B dense flagship for serious local inference. All four are natively multimodal, accepting text and image input and emitting text output.

Two architectural choices matter for local users:

• Multi-Token Prediction (MTP) on the 26B A4B: the model speculatively decodes multiple tokens per forward pass and verifies them in a single batched step, yielding roughly 3x throughput at equivalent quality.
• Selective expert routing on the MoE variant keeps active VRAM around 16 GB at Q4_K_M while the full 26B weights stream from system RAM — making it viable on a single RTX 4080 or RTX 5070 Ti.

If you are new to local inference, start with our local LLM guides hub or skim the model catalog for a side-by-side spec sheet.

Hardware requirements by variant

The table below assumes Q4_K_M quantization (Ollama's default) and a 4k context window. Higher context or Q5/Q8 quants scale VRAM roughly linearly.

Variant	Parameters	Q4_K_M VRAM	Recommended GPU	CPU fallback
Gemma 4 E2B	2.4 B	~6 GB	RTX 3060 12 GB, M2/M3 8 GB	16 GB RAM, 8–12 tok/s
Gemma 4 E4B	4.3 B	~9 GB	RTX 4060 Ti 16 GB, M3 Pro 18 GB	32 GB RAM, 3–5 tok/s
Gemma 4 26B A4B	26 B (4 B active)	~16 GB active + 12 GB RAM	RTX 4080 16 GB, RTX 5070 Ti 16 GB	Not recommended (MoE thrashes)
Gemma 4 31B	31 B	~22 GB	RTX 4090 24 GB, RTX 6000 Ada	64 GB RAM, <1 tok/s

Installing Ollama and pulling Gemma 4

Ollama remains the lowest-friction runtime for Gemma 4. Below are the four canonical pulls plus a verification step that catches the streaming bug Daniel Vaughan documented on Apple Silicon in April 2026.

Step 1: Install Ollama

# macOS / Linux
curl -fsSL https://ollama.com/install.sh | sh

# Windows: download installer from ollama.com/download/windows

Pin a known-good version. The Gemma 4 launch coincided with a streaming regression in Ollama 0.6.0–0.6.6 that broke tool-calling on M-series chips. Confirm 0.6.7 or later:

ollama --version

Step 2: Pull the right variant

ollama pull gemma4:2b         # E2B, ~1.8 GB on disk
ollama pull gemma4:4b         # E4B, ~3.1 GB
ollama pull gemma4:26b-a4b    # MoE, ~15 GB
ollama pull gemma4:31b        # dense flagship, ~19 GB

Step 3: Set a sane context window

Ollama defaults to 2k context, which truncates real prompts. Override at runtime or in a Modelfile:

ollama run gemma4:4b --ctx 8192
# or in a Modelfile: PARAMETER num_ctx 8192

Step 4: Smoke-test multimodality

ollama run gemma4:4b "Describe this image" /path/to/image.png

If the model replies I cannot see images, you have an older non-multimodal pull. Re-pull explicitly against the :4b tag and confirm against the official Ollama Gemma 4 page.

Benchmarks: Gemma 4 vs Qwen 3 vs Llama 3.3

The numbers below combine Google's April 2026 release benchmarks with independent runs from the BestLLMfor benchmark pipeline. Local results use Q4_K_M on an RTX 4090 24 GB at 4k context, batch=1.

Model	MMLU	HumanEval	GSM8K	MMMU (multimodal)	Decode tok/s (Q4)
Gemma 4 E4B	71.2	68.4	78.1	54.9	92
Llama 3.3 8B	69.8	62.1	74.3	n/a (text only)	87
Qwen3 8B	72.5	71.0	79.4	n/a	89
Gemma 4 26B A4B (MTP)	78.6	76.2	85.3	62.4	104
Gemma 4 31B	81.1	78.0	87.9	66.1	38
Qwen3 32B	80.4	82.1	86.5	n/a	34

Three editorial takeaways:

• E4B punches above its weight on math and code thanks to expanded reasoning post-training. It is the strongest 4B-class model we have benchmarked for math homework or autocomplete daemons.
• 26B A4B is the throughput champion. MTP gives it 104 tok/s decode — faster than most 8B dense models — at quality near the 31B flagship.
• 31B vs Qwen3 32B is a tie that splits by task. Gemma wins multimodal (Qwen3 32B is text-only at parity size) and math; Qwen3 wins HumanEval by ~4 points.

Methodology and raw logs are published per our benchmarking methodology, and the underlying scores feed the BestLLMfor public benchmarks API (CC BY 4.0) consumed by our catalog and the open-source MCP server.

Multi-Token Prediction in practice

MTP is the headline feature for local users. Standard autoregressive decoding emits one token per forward pass; MTP heads predict the next k tokens speculatively and verify them in a single batched step. On Gemma 4 26B A4B with k=4 we measure a 2.7–3.1x speedup over a hypothetical dense 26B at the same VRAM budget.

Two caveats before you wire MTP into an agent loop:

• Speedup degrades on diverse outputs. Highly structured generation (JSON, code) hits the upper bound; creative writing at high temperature falls to ~1.8x.
• Backend support is uneven. Ollama exposes MTP transparently and vLLM 0.7+ ships native support. llama.cpp added experimental kernels in May 2026 — see the Unsloth Gemma 4 documentation for current backend status and fine-tune notebooks.

Cost: local Gemma 4 vs hosted APIs

Assume a developer processes 5 M input + 1 M output tokens per month — a realistic workload for a coding assistant plus document Q&A.

Option	Monthly cost	Latency (p50 TTFT)	Notes
Gemma 4 31B local (RTX 4090)	~$8 electricity	180 ms	GPU amortized at $0/mo if already owned
Gemma 4 26B A4B local	~$6 electricity	120 ms	Best perf/cost; runs on 16 GB cards
Gemini 2.5 Flash API	~$4.20	~400 ms	No local infra, vendor lock-in
Claude Haiku 4.5 API	~$11.50	~350 ms	Higher quality, higher cost

At this volume hosted Gemini is marginally cheaper, but the break-even tips toward local around 15 M tokens/month — exactly where many internal tools land. Run your own numbers in the calculator.

Known issues and gotchas

• Ollama 0.6.0–0.6.6 streaming bug on Apple Silicon: tool calls return empty deltas. Fix: upgrade to 0.6.7+ or 0.7.x.
• Vision token budget: each image consumes ~256 tokens of context. Long PDF pipelines blow through 8k context fast — bump num_ctx to 32k.
• 26B A4B on AMD ROCm: experimental as of June 2026. CUDA and Metal are stable; ROCm hits a kernel-selection bug with MTP heads.
• Quantization quality cliff: Q3_K_M loses ~6 points on HumanEval vs Q4_K_M. Do not go below Q4 unless VRAM-starved.
• Safety filter false positives: Gemma 4's built-in refusals trigger on benign security and pentest prompts more often than Llama 3.3. Use a system prompt to set context.

Verdict: which Gemma 4 should you pull?

If you have...	Pull	Why
8 GB GPU or M2 laptop	gemma4:2b	Only viable option; surprisingly capable for size
12–16 GB GPU	gemma4:4b	Beats Llama 3.3 8B on math, fits comfortably
RTX 4080/5070 Ti, throughput priority	gemma4:26b-a4b	MTP makes it the fastest high-quality local model in 2026
RTX 4090/6000, quality priority	gemma4:31b	Best multimodal local model; ties Qwen3 32B on text
Code-heavy workload	Qwen3-Coder 32B Q4_K_M	Gemma 4 31B loses HumanEval; see best coding LLMs

For most readers with a 16 GB card, the answer is Gemma 4 26B A4B. It is the first local MoE that meaningfully outperforms dense alternatives on a single consumer GPU, and MTP makes it feel like running a 7B model. The 31B is worth the extra VRAM only if multimodal quality is non-negotiable. For details on each tag — sizes, license, multimodal support — cross-reference the 31B model page on ollama.com.
