## Limitations

The official project-linked collection identifies this public 3B checkpoint. The README uses a separate unavailable WebShepherd/web-shepherd-base URL; redirect equivalence is not asserted. Two safetensors shards and a Qwen2 causal-language-model configuration are present. No model card or weight license is published in the inspected manifest. The separately announced multimodal 3B model is not assumed released.
