Green L

by GreenPT

Green L is GreenPT's fast everyday model, built on Mistral Small 3.2 with 24 billion parameters. GreenPT positions it for multilingual writing and image understanding, and adds Dutch grammar guardrails on top of the base model. It handles text, images, and documents, with a 128K-token context window and up to 32K output tokens. Green L ships with GreenPT's built-in sustainability system prompt, which is applied automatically; if you send your own system prompt, both are sent and GreenPT's rules win on conflict. GreenPT also offers Green L Raw with identical specifications and no built-in system prompt, for callers who want full control over instructions. It fits writing assistance, everyday chat, and light image or document understanding, especially for Dutch-language content.
