When to pick which
distilled from the pricing and spec data above- cost dominates: $2.00/Mtok blended vs $2.15 — 7% less on the same 50/50 token mix
- your workload re-reads context (agents, RAG, long chats): cached input costs $0.150/Mtok — 88% off its list input price
- you want open weights — self-host it, fine-tune it, or exit the API entirely; Muse Spark 1.1 is closed
- provider flexibility: available from 2 providers, so you can price-shop hosts or fail over
