OpenAI

proxium calls OpenAI with your own OpenAI key. Your applications send their requests to proxium with a proxium virtual key. They never hold the OpenAI key.

Add OpenAI to a project​

  1. Get a key from OpenAI at platform.openai.com/api-keys.
  2. In the console, open Providers and select Add a vendor.
  3. In What are you adding, select OpenAI. proxium fills in the base URL and the models.
  4. Paste the key into API key, and select Add OpenAI.

proxium stores the key encrypted with AES-256-GCM. The console does not show the key again.

Models​

A new OpenAI vendor starts with these models. You can change the list on the Providers screen.

  • gpt-4o
  • gpt-4o-mini
  • o3-mini

Call a model​

A vendor that you add has the provider id t.<project>.openai, where <project> is the project slug. Send GET /v1/models to get the exact ids that your key can use.

curl https://proxium.tech/v1/chat/completions \
  -H "Authorization: Bearer $PROXIUM_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "t.<project>.openai/gpt-4o", "messages": [{"role": "user", "content": "Hello"}]}'

You can also send a tier name, such as trial, in model. proxium then picks the model from the routing policy of the project. Refer to Routing.
