When to pick which
distilled from the pricing and spec data above
Pick Solar Pro 4 if…
- cost dominates: $0.052/Mtok blended vs $1.00 — 94.8% 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 Sonar doesn't offer
- you need the longer context: 524K tokens vs 200K (2.6×)
Pick Sonar if…
- this pairing gives Sonar no edge on price, context, cache discount, or measured performance — pick it only for qualitative fit (ecosystem, compliance, model behavior on your prompts)
