When you want to run frontier models locally, you hit the same constraints repeatedly.
Cloud APIs lock you into specific providers and pricing structures. Every inference request leaves your environment. Sensitive data, proprietary workflows, internal knowledge bases - all of it goes through someone else's infrastructure. You pay per token whether you need the full model capabilities or not.
Self-hosting gives you control, but integration becomes the bottleneck. Your local model works perfectly in isolation, but connecting it to production systems means building your own API layer, handling authentication, managing routing, and maintaining uptime. A model that runs beautifully on your workstation becomes a deployment nightmare when you need to expose it to your application stack.
Hardware utilization suffers in both scenarios. Cloud providers charge for idle capacity. Self-hosted models sit unused between bursts of traffic. You're either paying for compute you don't use or scrambling to scale when demand spikes.
Google's Gemma 4 changes one part of this equation. Released April 2, 2026 under Apache 2.0, it delivers four model sizes (E2B, E4B, 26B MoE, 31B dense) built from Gemini 3 research that run on your hardware without sacrificing capability.
Clarifai Local Runners solve the other half: exposing local models through production-grade APIs without giving up control. Your model stays on your machine. Inference runs on your GPUs. Data never leaves your environment. But from the outside, it behaves like any cloud-hosted endpoint - authenticated, routable, monitored, and ready for integration.
This guide shows you how to run Gemma 4 locally and make it accessible anywhere.
Built from Gemini 3 Research, Optimized for Edge
Gemma 4 isn't a scaled-down version of a cloud model. It's purpose-built for local execution. The architecture includes:
The E2B and E4B models run offline on smartphones, Raspberry Pi, and Jetson Nano with near-zero latency. The 26B MoE and 31B dense models fit on single H100 GPUs or consumer hardware through quantization. You're not sacrificing capability for local deployment - you're getting models designed for it.
What Clarifai Local Runners Add
Local Runners bridge local execution and cloud accessibility. Your model runs entirely on your hardware, but Clarifai provides the secure tunnel, routing, authentication, and API infrastructure.
Here's what actually happens:
This isn't just convenience. It's architectural flexibility. You can:
Model Sizes and Hardware Requirements
Gemma 4 ships in four sizes, each available as base and instruction-tuned variants:
| Model | Total Params | Active Params | Context | Best For | Hardware |
|---|---|---|---|---|---|
| E2B | ~2B (effective) | Per-Layer Embeddings | 256K | Edge devices, mobile, IoT | Raspberry Pi, smartphones, 4GB+ RAM |
| E4B | ~4B (effective) | Per-Layer Embeddings | 256K | Laptops, tablets, on-device | 8GB+ RAM, consumer GPUs |
| 26B A4B | 26B | 4B (MoE) | 256K | High-performance local inference | Single H100 80GB, RTX 5090 24GB (quantized) |
| 31B | 31B | Dense | 256K | Maximum capability, local deployment | Single H100 80GB, consumer GPUs (quantized) |
The "E" prefix stands for effective parameters. E2B and E4B use Per-Layer Embeddings (PLE) - a secondary embedding signal feeds into every decoder layer, improving intelligence-per-parameter at small scales.

Prerequisites
Step 1: Install Clarifai CLI and Login
Log in to link your local environment to your Clarifai account:
Enter your User ID and Personal Access Token when prompted. Find these in your Clarifai dashboard under Settings → Security.
Step 2: Initialize Clarifai Local Runner
Configuration options:
--model-name: Gemma 4 variant (gemma4:e4b, gemma4:31b, gemma4:26b)--port: Ollama server port (default: 11434)--context-length: Context window (up to 256000 for full 256K support)Example for 31B with full context:
This generates three files:
Step 3: Start the Local Runner
(Note: Use the actual directory name created by the init command, e.g., ./gemma-4-e4b or ./gemma-4-31b)
Once running, you receive a public Clarifai URL. Requests to this URL route to your machine, execute on your local Ollama instance, and return results.
Set your Clarifai PAT:
Use the standard OpenAI client:
That's it. Your local Gemma 4 model is now accessible through a secure public API.
Local Runners are built for development, debugging, and controlled workloads running on your hardware. When you're ready to deploy Gemma 4 at production scale with variable traffic and need autoscaling, that's where Compute Orchestration comes in.
Compute Orchestration handles autoscaling, load balancing, and multi-environment deployment across cloud, on-prem, or hybrid infrastructure. The same model configuration you tested locally with clarifai model serve deploys to production with clarifai model deploy.
Beyond operational scaling, Compute Orchestration gives you access to the Clarifai Reasoning Engine - a performance optimization layer that delivers significantly faster inference through custom CUDA kernels, speculative decoding, and adaptive optimization that learns from your workload patterns.
When to use Local Runners:

Gemma 4 ships under Apache 2.0 with four model sizes designed to run on real hardware. E2B and E4B work offline on edge devices. 26B and 31B fit on single consumer GPUs through quantization. All four sizes support multimodal input, native function calling, and extended reasoning.
Clarifai Local Runners bridge local execution and production APIs. Your model runs on your machine, processes data in your environment, but behaves like a cloud endpoint with authentication, routing, and monitoring handled for you.
Test Gemma 4 with your actual workloads. The only benchmark that matters is how it performs on your data, with your prompts, in your environment.
