+# NEXS Qwen2.5-7B Multi-SLERP Merge
+
+A multi-SLERP merge of Qwen2ForCausalLM domain experts covering **code and math**, produced with
+[mergekit](https://github.com/arcee-ai/mergekit). Part of the
+[NEXS multi-SLERP merge collection](https://huggingface.co/anjohn0077/NEXS-multislerp-merges).
+
+## Method
+
+Multi-SLERP (`multislerp`) performs barycentric spherical interpolation on a hypersphere for more than two models: it projects the models into the tangent space at their weighted Euclidean mean, interpolates, and projects back. Here it is run in **task-vector space** — each source's delta from the shared base model is computed, the deltas are spherically averaged with equal weight (`normalize_weights: true`, `eps: 1e-8`), and the result is added back to the base. Merging was done with [mergekit](https://github.com/arcee-ai/mergekit).
+
+All variants share an identical vocabulary (152064); no tokenizer reconciliation was needed.
