OpenCode

OpenCode is a terminal-based AI coding assistant. Quick start (no install):

npx @opperai/cli launch opencode

The CLI writes the Opper provider block into ~/.config/opencode/opencode.json and starts OpenCode. To wire it manually instead:

mkdir -p ~/.config/opencode
curl -o ~/.config/opencode/opencode.json https://raw.githubusercontent.com/opper-ai/setup/main/data/opencode.json
export OPPER_API_KEY=your-api-key

Vercel AI SDK

The Vercel AI SDK is a TypeScript toolkit for building AI-powered applications. Install the Opper provider package and pass any Opper model string to generateText, streamText, embed, or tool calls:

npm install @opperai/ai-sdk-provider ai

import { opper } from '@opperai/ai-sdk-provider';
import { generateText } from 'ai';

const { text } = await generateText({
  model: opper('openai/gpt-5.5'),
  prompt: 'Hello!',
});

Pass any Opper model string: opper('anthropic/claude-sonnet-4-6'), opper('gemini/gemini-2.5-flash'), opper('default'), etc. Session tracing: Wrap your model with opperSpan to group every call in a conversation under one trace in Opper:

import { wrapLanguageModel, generateText } from 'ai';
import { opper, opperSpan } from '@opperai/ai-sdk-provider';

const { middleware, handle } = opperSpan({ name: 'my-chat-session' });

const model = wrapLanguageModel({
  model: opper('openai/gpt-5.5'),
  middleware,
});

const { text } = await generateText({ model, prompt: 'Hello!' });
await handle.end(text); // closes the span

OpenClaw

OpenClaw is a personal AI assistant built on pi that runs on WhatsApp, Telegram, Discord, and other chat apps. Add Opper as a custom provider in ~/.openclaw/config.json:

{
  "env": { "OPPER_API_KEY": "your-api-key" },
  "agents": {
    "defaults": {
      "model": { "primary": "opper/anthropic/claude-opus-4-7" }
    }
  },
  "models": {
    "providers": {
      "opper": {
        "baseUrl": "https://api.opper.ai/v3/compat",
        "apiKey": "${OPPER_API_KEY}",
        "api": "openai-completions",
        "models": [
          { "id": "anthropic/claude-opus-4-7", "name": "Claude Opus 4.7 (Opper)" },
          { "id": "anthropic/claude-sonnet-4-6", "name": "Claude Sonnet 4.6 (Opper)" },
          { "id": "mistral/mistral-large", "name": "Mistral Large EU (Opper)" },
          { "id": "gemini/gemini-2.5-flash", "name": "Gemini 2.5 Flash EU (Opper)" }
        ]
      }
    }
  }
}

Switch models at any time:

openclaw models set opper/anthropic/claude-sonnet-4-6

This method gives you full model access with a single API key, but no session span tracing. For that, use the native pi extension.

pi

pi is a terminal-based coding agent. Quick start (no install):

npx @opperai/cli launch pi

The CLI adds an opper provider entry to ~/.pi/agent/models.json (idempotently, alongside any existing providers) and starts pi. For deeper integration (300+ Opper models, automatic session span tracing, and 7 multimodal tools), install the @opperai/pi-provider package:

pi install npm:@opperai/pi-provider
export OPPER_API_KEY=your-api-key

Then use /model inside pi to switch to any Opper model. The package also registers 7 multimodal tools directly in pi: image generation, image analysis, text-to-speech, speech-to-text, web search, web fetch, and embeddings. Load only the provider or only the tools:

{
  "packages": [
    {
      "source": "npm:@opperai/pi-provider",
      "extensions": ["extensions/provider.ts", "extensions/tools.ts"]
    }
  ]
}

Optional environment variables:

Variable	Description
`OPPER_AGENT_NAME`	Override the framework name sent in headers (default: `pi-code`)
`PI_IMAGE_SAVE_MODE`	Default image save mode: `tmp`, `project`, `global`, or `custom`

Hermes

Hermes is an open-source terminal agent by Nous Research. Quick start (no install):

npx @opperai/cli launch hermes

The CLI uses an isolated HERMES_HOME=~/.opper/hermes-home/ so your real ~/.hermes/ is untouched. Manual setup: To wire Opper into your existing Hermes setup, add your API key and register Opper as a named custom provider, then point the model block at it to make it the default:

# Add your Opper API key
echo 'OPPER_API_KEY=your-api-key' >> ~/.hermes/.env

# ~/.hermes/config.yaml
model:
  provider: opper
  default: anthropic/claude-opus-4-7

custom_providers:
  - name: opper
    base_url: https://api.opper.ai/v3/compat
    key_env: OPPER_API_KEY

Switch models mid-session:

/model custom:opper:anthropic/claude-opus-4-7
/model custom:opper:gemini/gemini-2.5-flash

Hermes discovers the available models from Opper automatically — the model picker lists the full Opper catalog without any per-model configuration.

Claude Code

Claude Code is Anthropic’s CLI. Quick start (no install):

npx @opperai/cli launch claude

The CLI sets ANTHROPIC_BASE_URL / ANTHROPIC_AUTH_TOKEN and starts Claude Code with traffic routed to Opper’s Anthropic-compatible endpoint. To wire it manually, export the variables in your shell, or add the same keys to .claude/settings.local.json under env:

export ANTHROPIC_BASE_URL=https://api.opper.ai/v3/compat
export ANTHROPIC_AUTH_TOKEN=your-api-key
export ANTHROPIC_DEFAULT_SONNET_MODEL=anthropic/claude-sonnet-4-6
export ANTHROPIC_DEFAULT_HAIKU_MODEL=anthropic/claude-haiku-4-5
export ANTHROPIC_DEFAULT_OPUS_MODEL=anthropic/claude-opus-4-7

Claude Desktop

Claude Desktop is Anthropic’s macOS / Windows desktop app. Both the chat and Claude Code surfaces inside the app run through whichever inference profile is active. Quick start (no install):

npx @opperai/cli launch claude-desktop

The CLI uses Claude Desktop’s documented third-party-inference mode (deploymentMode: "3p"). It writes an Opper profile to ~/Library/Application Support/Claude-3p/configLibrary/ on macOS (or %LOCALAPPDATA%\Claude-3p\configLibrary\ on Windows), pointing at Opper’s Anthropic-compatible endpoint. If Claude Desktop is already running, it is quit and reopened so the change takes effect immediately. The picker shows Opus, Sonnet, and Haiku with Opus 4.7 as the default; pass --model <id> to pin a different default. To revert Claude Desktop to standard Anthropic inference:

npx @opperai/cli agents uninstall claude-desktop

This flips deploymentMode back to "1p" and removes the Opper profile entry. Other tools’ third-party profiles and your own preferences are left untouched.

On first launch, macOS will prompt “opper would like to control Claude”. Accept this so the CLI can quit and reopen the app cleanly. Available on macOS and Windows. Anthropic does not ship a Linux build of Claude Desktop.

Cursor

Cursor is an AI-powered code editor. Download the Opper rules file for your language and drop it in your project to give Cursor context about the Opper SDKs.

Download the .mdc file for your language:
- Python: Download
- TypeScript: Download
Place it in your project at .cursor/rules/opper.mdc.
In Cursor, make sure the rule is set to Always.

Cline

Cline is an AI coding agent for VS Code. Add Opper as a provider in the Cline settings panel:

Select OpenAI Compatible as the API Provider.
Set the Base URL to https://api.opper.ai/v3/compat.
Enter your Opper API key.
Set the Model ID to any model available on Opper (e.g. gemini/gemini-2.5-flash).

Continue.dev

Continue.dev is an open-source AI code assistant for VS Code and JetBrains. Add Opper manually to ~/.continue/config.yaml:

models:
  - name: Gemini 2.5 Flash (EU)
    provider: openai
    model: gemini/gemini-2.5-flash
    apiKey: your-api-key
    apiBase: https://api.opper.ai/v3/compat
    roles:
      - chat
      - edit

GitHub Copilot

GitHub Copilot Chat and Agent mode in VS Code can be routed through Opper via the OAI Compatible Provider extension. Inline completions stay on GitHub’s own service. Quick start (no install):

npx @opperai/cli editors github-copilot-vscode

The CLI prompts before installing the community extension, then writes the Opper provider block into your VS Code user settings.json. Reload the window, then in Copilot Chat: model picker → Manage Models → OAI Compatible → paste your OPPER_API_KEY when prompted. To wire it manually instead:

Install the extension: code --install-extension johnny-zhao.oai-compatible-copilot

Add Opper to your VS Code user settings.json:

"oaicopilot.baseUrl": "https://api.opper.ai/v3/compat",
"oaicopilot.models": [
  {
    "id": "anthropic/claude-opus-4-7",
    "owned_by": "opper",
    "apiMode": "openai",
    "context_length": 1000000
  }
]

Open Copilot Chat → model picker → Manage Models → OAI Compatible → paste your Opper API key when prompted.

Copilot Business / Enterprise users may need their org admin to enable the “Bring Your Own Language Model Key in VS Code” policy.
