GPT 6 Luna - Unifically

GPT 6 Luna is OpenAI’s fastest and cheapest GPT-6 model, built for high-volume tasks like classification, extraction, and short chat replies. It accepts text and image input, returns text, and has a context window of about 1 million tokens. More on this model: GPT 6 Luna API page.

Model

openai/gpt-6-luna


Provider	OpenAI
Name	GPT 6 Luna

Supported Endpoints

All three API formats are supported:

Chat Completions — POST /v1/chat/completions
Responses — POST /v1/responses
Messages — POST /v1/messages

Send LLM requests to https://direct-api.unifically.com, not https://api.unifically.com. The main host sits behind Cloudflare, and Cloudflare’s proxy timeout cuts most LLM requests short before the model has finished writing. When that happens you receive a truncated reply and are still charged for every token generated up to the cut-off. direct-api.unifically.com reaches the same API without the Cloudflare proxy, so long responses complete in full.

Example

curl -X POST https://direct-api.unifically.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "model": "openai/gpt-6-luna",
    "messages": [
      {"role": "user", "content": "Classify this support ticket as billing, bug, or feature request: My card was charged twice."}
    ]
  }'
