GPT 6 Luna
StandardOpenAI's fastest, most affordable GPT-6 tier for high-volume, latency-sensitive work.
1M-token context with surprisingly strong reasoning for its price. Ideal for classification, extraction, chat, and lightweight agent loops where speed and cost dominate.
▼
GPT 6 Luna is somewhat expensive at $0.10/M tokens input and $0.50/M tokens output. Cached input reads are priced at $0.01/M tokens, making repeated context cheaper. The model supports vision/image input, extended reasoning, a 1.1M context window.
