Relay Sports is an experimental fine-tuned derivative prepared by Yoseph Bagighni with AI development assistance. Upstream foundation model: Qwen/Qwen3-8B, created by the Qwen team at Alibaba Cloud. Starting format: mlx-community/Qwen3-8B-4bit. Exact local source/runtime hashes and training details accompany the release. The upstream Apache License2.0 is included in LICENSE. The original foundation was not trained from scratch by Relay; no exclusive ownership of upstream weights is claimed. The new trained weights provide an experimental sports/style adaptation, not comprehensive coaching or clinical expertise.
