When to pick which
distilled from the pricing and spec data above- cost dominates: $1.50/Mtok blended vs $1.56 — 4% less on the same 50/50 token mix
- your workload re-reads context (agents, RAG, long chats): cached input costs $0.075/Mtok — 90% off its list input price, a discount Grok 4.3 doesn't offer
- this pairing gives Grok 4.3 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 3.7 Flash costs $1.50/Mtok blended on Google.
