What actually differs
- Context window
- Identical — both accept 1M tokens, so context length is not a reason to pick either.
- Weights
- Both publish weights — Inkling under Apache 2.0 (open-weight), Muse Spark under proprietary (closed / API-only, not open-weights). Check the licences rather than assuming they permit the same commercial use.
- Recency
- Inkling shipped 98 days after Muse Spark (2026-07-15 vs 2026-04-08).
