Green R

by GreenPT

Green R (green-r) is GreenPT's own reasoning model. GreenPT states it is backed by OpenAI's open-weight GPT-OSS and ships with GreenPT's Sustainability system prompt, tuned for GreenPT's use cases. When a caller supplies its own system prompt, GreenPT sends both upstream as a single system message, the caller's first and the model's rules last. GreenPT lists a 128K-token context window and up to 32K output tokens, with text, image and document input and multilingual support. It targets advanced reasoning, analysis, writing and content generation. A raw twin, green-r-raw, exposes the same reasoning stack without the GreenPT system prompt, which suits applications that need full control of the instructions sent to the model.
