An OpenAI API alternative that is a one-line change

If you already call the OpenAI API, Text Generator accepts the same requests. You keep your code and gain a wider model choice and failover.

Same chat.completions.create call and response shape
Use GPT models or switch to Claude, Gemini, Grok, Kimi K3 or DeepSeek by changing the model string
text-generator/auto picks a model per request for quality, speed and cost
Pay-as-you-go credits with no mandatory subscription
