What actually differs
- Context window
- Identical — both accept 1M tokens, so context length is not a reason to pick either.
- Weights
- Laguna S 2.1 publishes weights (OpenMDW-1.1 (open-weight)); Muse Spark 1.3 is API-only. That decides self-hosting, air-gapped deployment and fine-tuning before any capability question does.
- Recency
- Muse Spark 1.3 shipped 43 days after Laguna S 2.1 (2026-09-02 vs 2026-07-21).
