OpenCodeReview

OpenCodeReview (command name ocr) is Alibaba's open-source AI code review CLI: it reads the Git diff and calls a large model for review comments. It ships with an OpenAI-compatible provider and also supports custom OpenAI-compatible gateways, so requests can be routed to aicentos.

PrerequisitesCopy anchor link

Create a dedicated key in the aicentos console (naming it ocr-ci makes usage easier to track). OCR only supports the OpenAI and Anthropic protocols; this guide uses OpenAI's Chat Completions path. Code review depends on the model's function calling capability, so pick a model that supports tool calling.

Configuration to fill inCopy anchor link

Setup stepsCopy anchor link

• Install the CLI (Node.js required, or Homebrew on macOS):

  Copy

  npm install -g open-code-review

• Write the configuration with the non-interactive commands; it ends up in ~/.opencodereview/config.json:

  Copy

  ocr config set provider                   openai
  ocr config set model                      claude-sonnet-5
  ocr config set providers.openai.url       https://aicentos.com/v1
  ocr config set providers.openai.api_key   your_api_key_here

• If you prefer a graphical walkthrough, run ocr config provider and ocr config model instead: pick the provider, enter the key and choose the model in the TUI, and a connectivity check runs automatically at the end.

TestCopy anchor link

Verify the endpoint on its own first:

ocr llm test

Once it passes, run a real review in any Git repository:

ocr review

NotesCopy anchor link

• The URL only goes up to /v1; do not extend it to the full /chat/completions.
• The configuration resolver needs all three of URL, key and model; merely exporting environment variables is not enough — anything missing must still be written into config.json, otherwise you get a 401.
• Environment variables can also override the configuration temporarily and take the highest precedence: OCR_LLM_URL / OCR_LLM_TOKEN / OCR_LLM_MODEL.
• For the built-in provider the field is providers.<name>.url; for custom providers it is custom_providers.<name>.url. Do not mix up the two maps.
• An insufficient account balance shows up as 401 / 403; check the balance on the wallet page first.
