Where GPT-6 Luna fits
The "Luna" in its name marks a lighter tier of OpenAI's lineup. Models like this are a common fit for high-volume work such as classification, extraction, tagging, routing and short replies, where cost per request matters most. By list price at a 3:1 input-to-output mix it is in the lowest-priced third of the 69 models on Bearer Club.
Its context window of 1,050,000 tokens can take very long inputs, such as long documents, large code files or long chat histories, in one request.
It is a closed model from OpenAI, so it is for Members and Executives only.
Bearer Club does not publish benchmark scores. Test GPT-6 Luna on your own prompts before you move traffic to it.

For security, abuse prevention and debugging we store request and response content, encrypted, and delete it after 30 days; error details may be kept longer. We also keep usage details (model, tokens, cost, latency, status and time). The model provider may keep requests briefly for abuse monitoring under its own terms.
Research Share: available. Opt in per key and pay less. Data from that key will be used to accelerate AGI and supplied to top frontier labs for AGI purposes, and only for traffic after you opt in.
