OpenAI models
All OpenAI models on Aether API: chat, image, audio, and embeddings behind one OpenAI-compatible key, with per-token pricing and at least 30% below OpenAI's own list price.
GPT chat models, image generation, audio, and embeddings, reachable through the same key as every other model.

How OpenAI models work on Aether API
- The request format is the OpenAI format, so the OpenAI SDK works after changing the base URL to
https://api.aetherapi.dev/v1. - Priced per token against prepaid credits, at least 30% below OpenAI's own list price.
- One key for OpenAI and every other provider in the catalogue, with spend limits per key.
