CI needs an OAuth token, not a classic PAT | | `openrouter` | `OPENROUTER_API_KEY` | Optional `OPENWIKI_OPENROUTER_PROVIDER_ONLY` allowlist | | `anthropic` | `ANTHROPIC_API_KEY` | Optional `ANTHROPIC_BASE_URL` | | `gemini` | `GEMINI_API_KEY` | Google AI Studio | | `gemini-enterprise` | Google ADC + `GOOGLE_CLOUD_PROJECT` | Optional `GOOGLE_CLOUD_LOCATION` (defaults to `global`) | | `bedrock` | AWS credentials + region | Explicit Bedrock keys or the AWS SDK default chain | | `baseten` | `BASETEN_API_KEY` | Optional `BASETEN_BASE_URL` | | `fireworks` | `FIREWORKS_API_KEY` | Optional `FIREWORKS_BASE_URL` | | `nebius` | `NEBIUS_API_KEY` | Nebius Token Factory | | `nvidia` | `NVIDIA_API_KEY` | Optional `NVIDIA_BASE_URL` | | `openai-compatible` | `OPENAI_COMPATIBLE_API_KEY` | Requires `OPENAI_COMPATIBLE_BASE_URL` and a custom model ID | Credentials and defaults are stored in `~/.openwiki/.env`. Process environment values take priority over file values. You can set the active provider and model with: ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} OPENWIKI_PROVIDER=openai OPENWIKI_MODEL_ID=gpt-5.6-terra ``` ### Provider retries Override retries after the first provider request: ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} OPENWIKI_PROVIDER_RETRY_ATTEMPTS=3 ``` The value must be a positive integer. If unset, OpenWiki defaults to 3 retries. ## GitHub Copilot To use GitHub Copilot: 1. Select GitHub Copilot during `openwiki --init`. If you have an active GitHub CLI session, OpenWiki can reuse it. Otherwise, run `gh auth login` from the credential prompt. 2. Choose a model (for example `gpt-5.5`). OpenWiki leaves the GitHub CLI token in the GitHub CLI credential store. It does not copy that token into `~/.openwiki/.env`. For CI or headless environments without a GitHub CLI session, set `COPILOT_API_KEY` to a GitHub **OAuth token**. Personal Access Tokens (classic or fine-grained) are rejected by the Copilot API for third-party integrations. ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} OPENWIKI_PROVIDER=copilot OPENWIKI_MODEL_ID=gpt-5.5 ``` ## OpenAI (ChatGPT login) The `openai-chatgpt` provider calls OpenAI's Codex backend using your ChatGPT subscription instead of a metered API key: ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} OPENWIKI_PROVIDER=openai-chatgpt openwiki code --init ``` The wizard opens the OpenAI auth page in your browser (and prints the URL for headless use). After sign-in, OpenWiki stores managed OAuth tokens in `~/.openwiki/.env` and refreshes the access token automatically. Treat the refresh token like a password. ## Gemini Enterprise (Vertex AI) The `gemini-enterprise` provider uses Google Application Default Credentials. No API key is required: ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} OPENWIKI_PROVIDER=gemini-enterprise GOOGLE_CLOUD_PROJECT=your-gcp-project GOOGLE_CLOUD_LOCATION=global ``` The credentials need Vertex AI access (`roles/aiplatform.user`), and the models you use must be enabled in Model Garden. Partner/open-weight (MaaS) models are region-specific, so set `GOOGLE_CLOUD_LOCATION` explicitly when using them. ## AWS Bedrock ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} OPENWIKI_PROVIDER=bedrock BEDROCK_AWS_ACCESS_KEY_ID=your-access-key-id BEDROCK_AWS_SECRET_ACCESS_KEY=your-secret-access-key BEDROCK_AWS_REGION=us-east-1 OPENWIKI_MODEL_ID=anthropic.claude-sonnet-5 ``` When explicit Bedrock credentials are not set, OpenWiki uses the AWS SDK default credential provider chain. Paste the Bedrock model ID directly. Some newer models require a cross-region inference profile ID (for example `us.anthropic.claude-sonnet-5`) instead of the bare model ID. ## OpenAI-compatible endpoints Use the `openai-compatible` provider for gateways or local servers that expose OpenAI-compatible chat completions: ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} OPENWIKI_PROVIDER=openai-compatible OPENAI_COMPATIBLE_API_KEY=your-gateway-key OPENAI_COMPATIBLE_BASE_URL=https://your-gateway.example.com/v1 OPENWIKI_MODEL_ID=your-gateway-model-name ``` Local examples such as Ollama (`http://localhost:11434/v1`) and LM Studio (`http://localhost:1234/v1`) use the same pattern. OpenWiki still requires `OPENAI_COMPATIBLE_API_KEY` even when the local server ignores the key value. ## OpenRouter provider pinning When OpenRouter serves a model through multiple upstream providers, restrict routing: ```bash theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}} OPENWIKI_PROVIDER=openrouter OPENROUTER_API_KEY=your-key OPENWIKI_OPENROUTER_PROVIDER_ONLY=Novita ``` ## See also * [Quickstart](/oss/openwiki/quickstart) * [CLI reference](/oss/openwiki/cli-reference) * [Customize OpenWiki](/oss/openwiki/customize) ***
