- your workload re-reads context (agents, RAG, long chats): cached input costs $0.050/Mtok — 90% off its list input price, a discount Reka Core doesn't offer
- you need the longer context: 1M tokens vs 128K (8.2×)
- this pairing gives Reka Core no edge on price, context, cache discount, or measured performance — pick it only for qualitative fit (ecosystem, compliance, model behavior on your prompts)
The cheaper option here — Gemini 3 Flash Preview costs $1.13/Mtok blended on Google.
