OpenCode Now Works with GMI Cloud

GMI Cloud is now a native provider inside OpenCode, which means you can connect to the full GMI model catalog directly from the terminal with no custom configuration required.

This post covers what OpenCode is, what makes it different from other coding tools, and how to get up and running with GMI Cloud in just a few minutes.

What is OpenCode?

OpenCode is an open-source AI coding agent that runs in your terminal.  It is available as a terminal UI, a desktop application, and an IDE extension for VS Code, Cursor, and similar tools.

Unlike IDE-based tools that require you to switch windows or rely on a single provider, OpenCode treats models as interchangeable. It supports over 75 LLM providers, including Claude, OpenAI, Google Gemini, local models via Ollama, and now GMI Cloud.  You pick the provider, you pick the model, and you can switch mid-session without losing your conversation context.

OpenCode works directly inside any project folder. It reads your files, reasons about the codebase, and makes changes with your approval. The interface shows you what it is doing at every step, so you stay in control without having to manage individual file edits manually.

Two Modes Worth Knowing

OpenCode ships with two primary agents that cover most development workflows.

Plan is a read-only mode where OpenCode analyzes the codebase and proposes an implementation approach without making any changes.  This is useful before starting a complex feature, when you want to validate assumptions, or when you are working in a sensitive part of the codebase. In Plan mode, you iterate on the approach with the agent until the plan looks right, then switch to Build.

Build is the default mode with full tool access. The agent reads files, makes edits, creates new files, and runs commands.  You can undo any changes at any point using the /undo command. Switching between modes is done with the Tab key.

AGENTS.md: Giving OpenCode Context About Your Project

One of the most useful features in OpenCode is AGENTS.md.  This is a markdown file you place in your project root that contains instructions specific to your codebase: the stack you use, coding conventions, folder structure, testing requirements, and anything else the model should know before touching your code.

You can generate it automatically by running /init inside OpenCode. The agent scans your project and creates an AGENTS.md with concise project-specific guidance.  This file is included in the model's context at the start of every session, which significantly improves the quality and consistency of responses over time.

You can also maintain a global AGENTS.md at ~/.config/opencode/AGENTS.md that applies across all your projects.

Why GMI Cloud

GMI Cloud is a venture-backed AI infrastructure company that raised $82 million in Series A funding.  It operates NVIDIA H100 and H200 GPU clusters across data centers in the US and APAC.

For developers, what matters is the model catalog. Through the GMI Cloud API you get access to Claude, GPT, DeepSeek, Gemini, Qwen3-Coder, and more through a single OpenAI-compatible endpoint.  Because GMI Cloud is a native provider inside OpenCode, you do not need to manually configure base URLs or write custom JSON. You connect once and all available models appear in the OpenCode model picker.

Connecting GMI Cloud to OpenCode

Once OpenCode is installed and you are inside a project, type:

/connect

A provider list will appear. Scroll down and select GMI Cloud, then press Enter.

When prompted for an API key:

1. Go to console.gmicloud.ai
2. Navigate to API Keys
3. Click Create API Key and copy it
4. Paste it into OpenCode and press Enter

GMI Cloud is now connected. To browse available models, type:

/models

The model picker opens showing the full GMI Cloud catalog. You can switch models at any time during a session without losing context.

Recommended Models for Coding

‍

‍

The right model depends on what you are working on. For complex multi-file tasks or unfamiliar codebases, Qwen3-Coder-480B or DeepSeek V4 Pro give you the most reasoning depth.  For faster iteration on smaller tasks, DeepSeek V4 Flash keeps latency low.
