internlm/Intern-S1
internlm/Intern-S1 is a internlm record on this register. The Hugging Face model API lists the pipeline tag as image-text-to-text. The safetensors index gives an exact parameter count of 240,709,856,128. Architectural context length (max_position_embeddings) is 65,536. The listed licence is apache-2.0. The Hub repository was created on 24 Jul 2025, which is the release date this register uses.
Primary source: the Hugging Face model card for internlm/Intern-S1. Fields below come from that card, the Hub model API, and the repository’s own config.json when those files exist. A field we cannot source is omitted rather than guessed.

How to run
Safetensors weights are on the Hugging Face repository. The parameter count on this page came from that index.
The Hugging Face model API lists the library as transformers.
Load it from huggingface.co/internlm/Intern-S1. This page does not add install steps that the Hub files do not state.
