Nanbeige 4.3-33B, an open-weight large language model, was released by the Nanbeige team.

What it means

Nanbeige 4.3-33B is an open-weight large language model with 33 billion parameters, released by the Nanbeige team. The '4.3' designates an iteration in their 4.x model series, and '33B' specifies the parameter count. Open-weight means the trained model weights are publicly accessible, allowing anyone to download, run locally, fine-tune, or inspect them. The release likely includes model weights and a model card hosted on platforms like Hugging Face.

Accuracy & sourcesGrounded

The claim originates from a post on r/LocalLLaMA that links directly to the official Hugging Face repository for Nanbeige 4.3-33B. As a primary-source release (the model weights and model card are the authoritative record), the claim is solidly based on the actual release.
