GPT 5.6 Luna
OpenAI's fastest, most affordable GPT-5.6 tier — for high-volume, latency-sensitive, and budget-conscious workloads.
From OpenAI, GPT 5.6 Luna is a cloud text model. It is multimodal: alongside a text prompt it accepts images, then replies with generated text. Its context window handles up to 1.05M input tokens and up to 128K output tokens, and it supports adjustable reasoning effort for harder problems. It runs through Replicate using your own API key, from $1.00 per million input tokens.
