Looking for the plugin's configuration parameters? You can find them in the AI Request Transformer configuration reference doc.

The AI Request Transformer plugin uses a configured LLM service to introspect and transform the client’s request body before proxying the request upstream.

This plugin supports llm/v1/chat style requests for all of the same providers as the AI Proxy plugin.

It also uses all of the same configuration and tuning parameters as the AI Proxy plugin, under the config.llm block.

The AI Request Transformer plugin runs before all of the AI Prompt plugins and the AI Proxy plugin, allowing it to also introspect LLM requests against the same, or a different, LLM.

How it works

Figure 1: The diagram shows the journey of a consumer’s request through Kong Gateway to the backend service, where it is transformed by both an AI LLM service and Kong’s AI Request Transformer and the AI Response Transformer plugins.

  1. The Kong Gateway admin sets up an llm: configuration block, following the same configuration format as the AI Proxy plugin, and the same driver capabilities.
  2. The Kong Gateway admin sets up a prompt for the request introspection. The prompt becomes the system message in the LLM chat request, and prepares the LLM with transformation instructions for the incoming user request body.
  3. The user makes an HTTP(S) call.
  4. Before proxying the user’s request to the backend, Kong Gateway sets the entire request body as the user message in the LLM chat request, and then sends it to the configured LLM service.
  5. The LLM service returns a response assistant message, which is subsequently set as the upstream request body.
