Integrate RodiumAI with OpenCode in your project

Add RodiumAI as a custom provider in OpenCode Desktop in 4 steps: Settings → Providers → Custom provider, paste your base URL and API key, add your models from the RodiumAI catalog, and start coding.

Why OpenCode + RodiumAI?

OpenCode is an AI-powered coding agent available as a desktop app. It supports any OpenAI-compatible provider through its custom provider feature — which means you can connect RodiumAI directly from the settings UI, no config file needed.

With RodiumAI you get:

One API key for GPT, Claude, Gemini, DeepSeek, Mistral, and more.
RODI credits rechargeable via Mobile Money (Orange, MTN, Wave…) or bank transfer.
Smart routing profiles (auto, pro, fast) that balance cost and performance automatically.
Full usage visibility in your RodiumAI dashboard.

Prerequisites

Before starting, make sure you have:

A RodiumAI account — sign up at rodiumai.io.
At least one API key created in your dashboard (Dashboard → API Keys).
A positive RODI credit balance (Dashboard → Billing → Top up).
OpenCode Desktop installed — download at opencode.ai.

Note: Your RodiumAI API key starts with rd_sk_prod_ for production keys. It is only shown once at creation — if you lose it, use the Regenerate button in the dashboard.

Step 1 — Open Settings → Providers

Launch OpenCode Desktop. Click the ⚙️ Settings icon at the bottom left of the sidebar.

In the Settings panel, click Providers under the Server section.

Step 2 — Add a Custom provider

On the Providers page, you will see a list of popular providers. Scroll to the bottom and click + Connect next to Custom provider.

OpenCode Providers list — Custom provider option at the bottom with Connect button

A form opens asking for:

Provider ID — a unique identifier for this provider (e.g. rodiumai)
Display name — the label shown in the model selector (e.g. RodiumAI)
Base URL — the RodiumAI API endpoint
API key — your RodiumAI key

OpenCode — Custom provider form with Provider ID, Display name, Base URL and API key fields

Step 3 — Fill in the RodiumAI connection details

Get the Base URL

Go to rodiumai.io/docs and look for the Base URL section. All API samples use:

https://api.rodiumai.io/v1

RodiumAI Docs — Base URL https://api.rodiumai.io/v1 highlighted

Get your API key

Go to rodiumai.io/dashboard/api-keys. Your key is displayed in the format:

rd_sk_prod_u••••••••••••••••••••••••zeMK

Important: The full secret is only shown once at creation. Only the prefix and last 4 characters are stored on the RodiumAI side. If you no longer have the full key, click Regenerate to create a new one.

Fill in the form

Enter the details in the OpenCode Custom provider form:

Step 4 — Add your models

Still in the same form, scroll down to the Models section. Here you add each model you want to use from RodiumAI.

For each model, fill in two fields:

Model ID — the exact slug from the RodiumAI catalog
Display Name — the label shown in the UI (your choice)

Find model slugs

Go to rodiumai.io/models to browse the full catalog. Each model card shows its exact slug — for example:

openai/gpt-5.5
openai/gpt-5.5-pro
anthropic/claude-sonnet-4-6
google/gemini-2.5-flash
deepseek/deepseek-chat

Copy the slug exactly as shown and paste it into the Model ID field. Then type the display name you want to see in the model picker.

Click + Add model to add more models.

Step 5 — Save and restart OpenCode

Once all fields are filled, scroll down and click Save (or Submit depending on your version).

Then close and reopen OpenCode Desktop. This is required for the new provider and its models to appear in the model selector.

Step 6 — Select a RodiumAI model and start coding

Click the model selector at the bottom of the chat panel (next to Build). You will now see RodiumAi as a provider section in the list, with all the models you added.

Select the model you want and start sending requests. Your RODI credits are consumed per request and tracked in your dashboard.

Monitor your usage

Every request made by OpenCode consumes RODI credits. Track your spending in real time:

Go to rodiumai.io → Dashboard → Usage Logs
Filter by date range, model, or API key
Set up a low balance alert under Billing settings to avoid interruptions
