When to pick which
distilled from the pricing and spec data above- cost dominates: $1.30/Mtok blended vs $2.15 — 39.7% less on the same 50/50 token mix
- your workload re-reads context (agents, RAG, long chats): cached input costs $0.260/Mtok — 81% off its list input price
- you need the longer context: 1M tokens vs 256K (3.9×)
- you want open weights — self-host it, fine-tune it, or exit the API entirely; KAT-Coder-Pro V2.5 is closed
- provider flexibility: available from 2 providers, so you can price-shop hosts or fail over
