When to pick which
distilled from the pricing and spec data above- cost dominates: $0.052/Mtok blended vs $0.750 — 93% less on the same 50/50 token mix
- your workload re-reads context (agents, RAG, long chats): cached input costs $0.006/Mtok — 80% off its list input price, a discount Mistral Large 3 doesn't offer
- you need the longer context: 524K tokens vs 128K (4.1×)
- this pairing gives Mistral Large 3 no edge on price, context, cache discount, or measured performance — pick it only for qualitative fit (ecosystem, compliance, model behavior on your prompts)
Summary
Solar Pro 4 by Upstage costs $0.030/Mtok input and $0.120/Mtok output, with a 524K-token context window. It supports text input.
