96 tokens per second. On consumer hardware. Gemma 4 didn’t just launch yesterday—by lunch, it was fixing real bugs in my codebase.
Google’s latest open model drop. Impressive specs on paper. But papers lie. Or at least, they hype. I fired up my home lab—two NVIDIA RTX 5060 Ti cards, 32GB VRAM total—and had it humming at speeds that smoke the official benchmarks.
Here’s the thing. Stock llama.cpp? Crashed hard. ‘Unknown model architecture: gemma4.’ No surprise. Google’s ahead of the curve, as usual. Or thinks it is.
Why Hack Your Own llama.cpp Build?
Tried the CUDA image first. Nope. Built from HEAD myself. Kaniko job on the cluster. Fifteen minutes later, custom image in my registry. No GitHub Actions dance. No cloud bills.
Dockerfile? Straightforward. Clone llama.cpp master, cmake with CUDA for Ampere and Blackwell. SM 86;120. Pushed to the same Kubernetes that runs inference. Self-hosted everything. It’s 2024—why trust outsiders with your ML stack?
Deploy command: llmkube deploy gemma4-26b –gpu –cuda –gpu-count 2. Model from Hugging Face, Q4_K_M at 15.6GB. Flash attention, Jinja templating, 32K context. Operator handles the Kubernetes grunt work. Health probes. OpenAI endpoint. Done.
Three minutes from command to first token. Mostly download. Then—bam. 96 tok/s generation. 128 tok/s prompts. Aggregate throughput? 170 under load. Zero errors. P50 latency at 2 seconds.
For context, the generic benchmarks floating around say Gemma 4 26B-A4B “exceeds 40 tok/s on consumer hardware.” We’re doing 96 tok/s on a single request and 170 tok/s aggregate under concurrent load.
That’s the original poster’s flex. And it’s legit. MoE magic—only 4B active params per token. Dual GPUs split the load like pros. Official numbers? Laughable.
But speed’s worthless without smarts. I threw real bugs at it. My own project. Kubernetes rolling updates deadlocking on GPUs. New pod can’t grab resources; old one clings like a bad ex.
Gemma 4? Nailed it. ‘Use Recreate strategy, not RollingUpdate. Conditional on GPU count.’ Chain-of-thought reasoning. Edge cases covered. Full YAML patch. 10.6 seconds for 1024 tokens.
Next: Orphaned Endpoints after deleting InferenceServices. Output? Production Go code. UnregisterEndpoint method. DNS sanitization. Service/Endpoint cleanup. NotFound handling. Logs. Spot-on.
11.1 seconds.
Tests? Matched my Gomega suite exactly. BeforeEach. ContainElements. NotTo(ContainElement). Four cases. 12.3 seconds.
Impressive. Not Claude-level. Reasoning dips on hairy multi-steps. Cuts off at limits sometimes. But good enough for 80% of dev drudgery.
Can Gemma 4 Run on Your Gaming Rig?
Short answer: Yes. If you’ve got 32GB VRAM. My Ryzen 9, Ubuntu 24.04, MicroK8s. NVIDIA 590 drivers. Scale down to one 4090? Still viable. Q4 quant keeps it lean.
The real win? Gap from ‘Google announces’ to ‘your hardware hums’ shrank to hours. Not weeks of waiting for quantized GGUF ports or enterprise distros.
Google’s PR spin? ‘Open models for everyone!’ Cute. But they know most devs won’t build from source. Or manage K8s operators. That’s the moat—subtle incompetence barrier.
I did it anyway. LLMKube handles the ops. One CRD for model, one for service. No babysitting.
Here’s my unique gripe-turned-prediction: This is the Homebrew moment for AI inference. Remember early CUDA? NVIDIA dropped binaries; hackers brewed their own. Sparked a GPU revolution. Gemma 4’s the same. Devs will fork, quantize, optimize locally. Cloud giants like Anthropic? They’ll whine about ‘safety’ while we run circles around their $20/request APIs.
Bold call: By EOY, 50% of indie devs ditch cloud LLMs for local MoE beasts like this. Electricity bill? $0.02 per million tokens. Try pricing that against Grok.
Why Does This Crush Official Benchmarks?
Tables don’t lie.
Generation: 96 tok/s. Prompt: 128 tok/s. Model: 15.6GB. Throughput: 170 tok/s aggregate. 110 requests. 0% errors.
Generic blogs? ‘Over 40 tok/s.’ Pfft. Single-node myths. No concurrency. No real load.
MoE shines here. 26B total, 4B active. KV cache sips 16GB leftover VRAM. 32K context? No sweat.
Skeptical? Run it. But don’t blame me if your electric meter spins.
Corporate hype check. Google open-sources Gemma to ‘democratize AI.’ Sure. While pushing Vertex AI hard. This local speed? Undercuts their own cloud pitch. Accidental rebellion?
Bug fixes weren’t fluff. Production code. Matches my style. I’d merge 90% as-is.
Limits? Yeah. Complex chains falter. Hallucinations on niche K8s arcana. But iterate—prompt better, chain models. It’s a tool, not a god.
The Dark Side: Still Not GPT-4o
Shallow reasoning on twists. Token cliffs mid-thought. Fine-tune it? GGUF makes that easy.
I’m claiming this: Local AI went from toy to teammate overnight. ShadowStack—my rig—now outperforms mid-tier clouds on latency and cost.
Historical parallel? Linux kernel patches in ‘95. Rough. Raw. But owned your stack. Gemma 4’s that for code gen.

Frequently Asked Questions
What is Gemma 4 and how do I deploy it?
Google’s open MoE model, 26B params. Deploy via llama.cpp on K8s or bare metal. Build from HEAD for support. Use Q4_K_M GGUF for speed.
How fast is Gemma 4 on consumer GPUs like RTX 4090?
96 tok/s single request on dual 5060 Ti. Expect 60-80 on single 4090. MoE efficiency crushes dense models.
Can Gemma 4 fix real production bugs?
Yes, for straightforward issues like K8s GPU scheduling or endpoint leaks. Generates merge-ready code in seconds. Complex logic? Needs human polish.
