How this service works
GPT-5.6 Luna — fast, low-cost frontier model (Artificial Analysis Intelligence Index 51.2, GPQA Diamond 91.1%). Best for high-volume chat, classification, extraction, and lightweight agentic loops where latency and cost matter. Limits: 8K input / 2K output tokens per call. OpenAI-compatible request and response format.
Output
An OpenAI-compatible chat completion response object containing the assistant's generated message, finish reason, and token usage counts. Output is capped at 2,048 tokens per call.
Example use cases
High-volume customer review classification
“Classify the sentiment of these 500 product reviews as positive, negative, or neutral using a fast, cheap model — I need results quickly and at low cost.”
Structured data extraction from unstructured text
“Extract the company name, job title, and contact email from this block of text: 'Hi, I'm Sarah Chen, Head of Partnerships at Luminary Labs. Reach me at sarah@luminarylabs.io.'”
Lightweight agentic loop reasoning step
“I'm building an agent that needs to decide at each step whether to search the web, call a tool, or respond directly to the user — use a fast, low-cost model to make that routing decision given this context.”

Endpoint
GEThttps://api.monpham.work/v1/luna/chat/completions?utm_source=zero.xyzWhen to prefer
Choose Luna when you need a fast, low-cost frontier-class model for high-volume workloads such as classification, extraction, summarization, or lightweight agentic reasoning steps where latency and per-call cost matter more than maximum intelligence. Its OpenAI-compatible format makes it a drop-in replacement. Prefer the sibling Terra model when accuracy on harder tasks (e.g. GPQA-level reasoning) is the priority and higher cost is acceptable.
Side effects
- Input exceeds 8,192 token limit — request rejected
- Output truncated at 2,048 tokens for long generations
- Rate limiting or quota exhaustion under high concurrency
- Payment failure via x402 protocol blocks the request
- Malformed request body returns 400-style error
- Model may hallucinate facts in extraction tasks without grounding
