Best estimate from public evidence; the vendor did not disclose every value. GPT-6 Luna served through the Decisions API, as identified by the exact OpenRouter checkpoint. OpenAI does not disclose parameter counts or architecture. Low-confidence estimates carry forward the existing GPT-6 Luna family record; these sources establish identity and closed API availability, not the estimated counts. The Decisions route returns typed choices and probabilities, without text generation or exposed reasoning controls.
