AI Proxy Advanced: OpenAI SDK: Chat route with dynamic model selection - Plugin

OpenAI SDK: Chat route with dynamic model selectionv3.8+

Configure a chat route that reads the target model from the request path instead of hardcoding it in the configuration.

For this plugin to work properly, you need a Gateway Route with the following configuration:
routes:
 - name: openai-chat
   paths:
     - "~/(?<model>[^#?/]+)/chat/completions$"
   methods:
     - POST

Applying this configuration will let you target different models dynamically using an OpenAI-compatible SDK. For example:

client = OpenAI(
  base_url="http://localhost:8000/gpt-4"
)

In this case, the Python SDK automatically expands the URL to http://localhost:8000/gpt-4/chat/completions, and Kong Gateway extracts the model name (gpt-4) from the path to route the request appropriately.

Prerequisites

This example requires the following variables to be added to your manifest. You can specify values at runtime by setting TF_VAR_name=value.

variable "openai_api_key" {
  type = string
}

Add this section to your declarative configuration file:

_format_version: "3.0"
plugins:

    config:
      targets:

          header_name: Authorization
          header_value: Bearer ${{ env "DECK_OPENAI_API_KEY" }}
        logging:
          log_statistics: true
          log_payloads: false
        model:
          provider: openai
          name: "$(uri_captures.model)"

Make sure to replace the following placeholders with your own values:

consumerGroupName|Id: The id or name of the consumer group the plugin configuration will target.

Make sure to replace the following placeholders with your own values:

region: Geographic region where your Kong Konnect is hosted and operates.
controlPlaneId: The id of the control plane.
KONNECT_TOKEN: Your Personal Access Token (PAT) associated with your Konnect account.
consumerGroupId: The id of the consumer group the plugin configuration will target.

See the Konnect API reference to learn about region-specific URLs and personal access tokens.

Next, apply the KongPlugin resource by annotating the KongConsumerGroup resource:

kubectl annotate -n kong  CONSUMERGROUP_NAME konghq.com/plugins=ai-proxy-advanced

Prerequisite: Configure your Personal Access Token

terraform {
  required_providers {

Add the following to your Terraform configuration to create a Konnect Gateway Plugin:
