OpenCode | HyperFlowSI Docs

OpenCode is an open-source coding agent for the terminal, desktop and IDEs. Add HyperFlowSI as an OpenAI-compatible provider and pick its models with /models.

Install OpenCode

curl -fsSL https://opencode.ai/install | bash

See OpenCode’s install guide for other options.

Set your key

export HYPERFLOW_API_KEY="sk-..."

Add HyperFlowSI as a provider

Add this to ~/.config/opencode/opencode.json:

opencode.json

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "hyperflow": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "HyperFlowSI",
      "options": {
        "baseURL": "https://ai.hyperflow.fun/v1",
        "apiKey": "{env:HYPERFLOW_API_KEY}"
      },
      "models": {
        "openai/gpt-6-luna": {
          "name": "GPT-6 Luna"
        }
      }
    }
  }
}

Add every HyperFlowSI model you want under models, keyed by its id from the Models page.

Start OpenCode

cd /path/to/your/project
opencode

Run /models and pick a HyperFlowSI model.

To keep the key out of the config file, leave out apiKey, run /connect inside OpenCode, choose Other, enter the provider id hyperflow and paste your key. OpenCode stores it in ~/.local/share/opencode/auth.json.

Troubleshooting

Authentication errors: check HYPERFLOW_API_KEY is set in the shell that starts OpenCode, or run /connect again.
Model not found: the key under models must match the model id exactly, such as openai/gpt-6-luna.
The agent doesn’t edit files: pick a model with tool calling.
