OpenCode Setup

OpenCode is an open-source terminal AI coding tool, similar to an open-source alternative to Claude Code. With OfoxAI, you can use any model.

Setup Steps

1. Install OpenCode


# macOS / Linux
curl -fsSL https://opencode.ai/install | bash
 
# Or install with Go
go install github.com/opencode-ai/opencode@latest

2. Configure Environment Variables

OpenCode supports multiple provider configurations. We recommend using OpenAI compatible mode:

~/.zshrc


# OpenAI compatible mode
export OPENAI_API_KEY=<your OFOXAI_API_KEY>
export OPENAI_BASE_URL=https://api.ofox.ai/v1

If you primarily use Claude models, you can configure Anthropic mode instead:

~/.zshrc


export ANTHROPIC_API_KEY=<your OFOXAI_API_KEY>
export ANTHROPIC_BASE_URL=https://api.ofox.ai/anthropic

3. Configuration File

You can also configure via OpenCode’s config file:

~/.config/opencode/config.toml


[providers.ofoxai]
api_key = "<your OFOXAI_API_KEY>"
base_url = "https://api.ofox.ai/v1"
 
[models.default]
provider = "ofoxai"
model = "anthropic/claude-sonnet-4.5"

4. Verify


opencode "Hello, how are you?"

Recommended Models

Scenario	Model	Description
Daily coding	`anthropic/claude-sonnet-4.5`	Balanced performance
Complex tasks	`anthropic/claude-opus-4.6`	Most capable reasoning
Quick tasks	`moonshotai/kimi-k2.5`	Low cost, high speed

OpenCode’s configuration options may change with version updates. See the OpenCode official documentation for the latest information.
