OpenCode is an AI coding agent that runs in your terminal. You can connect it to NagaAI by defining a custom provider in ~/.config/opencode/opencode.json and then authenticating with your NagaAI API key inside OpenCode.

​
Setup

1

Install OpenCode

Follow the official installation docs at https://opencode.ai/docs.You can install it with the official install script:
curl -fsSL https://opencode.ai/install | bash
Or install it with npm:
npm install -g opencode-ai
2

Create a NagaAI API key

Create an API key in the dashboard: https://naga.ac/dashboard.
If you’re new to NagaAI, follow the Quickstart first.
3

Add NagaAI as a custom provider

Open ~/.config/opencode/opencode.json and configure a custom provider named naga-ai:
{
  "$schema": "https://opencode.ai/config.json",
  "disabled_providers": [],
  "provider": {
    "naga-ai": {
      "name": "NagaAI",
      "npm": "@ai-sdk/openai",
      "models": {
        "gpt-5.4": {
          "name": "GPT 5.4",
          "limit": {
            "context": 1050000,
            "output": 128000
          },
          "modalities": {
            "input": ["text", "image"],
            "output": ["text"]
          }
        }
      },
      "options": {
        "baseURL": "https://api.naga.ac/v1"
      }
    }
  }
}
This example registers gpt-5.4, but you can add other NagaAI models too. For agentic coding, prefer models with tools support.

Connect your API key in OpenCode

Start OpenCode in your project directory:
opencode
Then run:
/connect
In the provider list:
  1. Select NagaAI
  2. Paste your NagaAI API key
  3. Save the credential

Choose the model and start coding

After connecting, select the configured NagaAI model in OpenCode and start your session.
The provider base URL should be https://api.naga.ac/v1.
