## Separately installed local model and runtime

The local runner uses the Ollama tag [`qwen2.5:7b`](https://ollama.com/library/qwen2.5:7b). The upstream [Qwen2.5-7B-Instruct model](https://huggingface.co/Qwen/Qwen2.5-7B-Instruct) identifies its license as Apache 2.0; its [full model license](https://huggingface.co/Qwen/Qwen2.5-7B-Instruct/blob/main/LICENSE) includes Copyright 2024 Alibaba Cloud. [Ollama's full runtime license](https://github.com/ollama/ollama/blob/main/LICENSE) is MIT, Copyright (c) Ollama. Consult those upstream license files for the separately installed model and runtime. The public application source archive contains neither model weights nor the Ollama binary.

The Sanity/React/other packages are installed from the package manifest and retain their own licenses and notices in their distributions. Original Access Atlas code is covered by its accompanying LICENSE. This notice was checked against the primary source and upstream license pages on 2 October 2026.
