Pull Gemma4:e4b with Ollama to Build a Local AI Coding Agent (v9.6)
Many developers run AI coding assistants from the cloud because it’s quick and the models are powerful. Yet that convenience comes with trade‑offs: ongoing fees, the need to ship proprietary code off‑site, and a black‑box view of how the agent actually works. If you’re watching your budget, protecting sensitive snippets, or just want to peek under the hood, a local stack can make sense.
This guide walks you through assembling one from three components—Ollama, Gemma 4, and OpenCode—so you end up with a self‑hosted coding agent that talks to a model running on your own machine. Ollama acts as the runtime, pulling and serving Gemma 4 locally and exposing a simple API that OpenCode can call. On Windows you can grab the installer from ollama.com/download or pull it via PowerShell with winget install Ollama.Ollama.
Once launched, the Ollama icon appears in the system tray, signalling that the service is ready in the background. From there, you’ll hook OpenCode up to the local LLM and start coding without ever leaving your device.
In PowerShell: ollama pull gemma4:e4b On Linux, use the same command: ollama pull gemma4:e4b You can check the downloaded model: ollama list On my machine, Ollama reports the following: gemma4:e4b 9.6 GB For reference, my laptop has an Intel i7-13800H CPU, 32 GB RAM, and an NVIDIA RTX 2000 Ada Laptop GPU with about 8 GB VRAM. You can choose gemma4:e2b instead if E4B feels too slow. The version of gemma4:e4b that we downloaded earlier is a 4-bit quantized model, with GGUF as the local model format used by Ollama runtimes. On my machine, Ollama reports gemma4:e4b supports with a 128K context length.
Why this matters
Can we truly run a capable coding assistant without sending anything to the cloud? By pulling Gemma 4:e4b into Ollama, we now have a 9.6 GB model that runs on a laptop with an Intel i7‑13800H, 32 GB RAM and an RTX 2000 Ada. The steps are simple—one `ollama pull` command on Windows or Linux, then `ollama list` to verify.
For developers worried about cost or data privacy, the appeal is clear: no recurring API fees, no external endpoints handling proprietary code. Yet the hardware prerequisites are non‑trivial; not every workstation matches the spec shown in the article. Moreover, the post assumes a level of comfort with command‑line tools that may limit broader adoption among less technical founders.
We appreciate the transparency of the guide, but remain uncertain whether the performance and reliability of a locally hosted Gemma 4 agent can consistently match that of cloud‑hosted alternatives. Until broader benchmarks emerge, the approach is a useful experiment rather than a guaranteed solution for all AI‑driven development workflows.
