Is Solar Pro 3 on the Pareto frontier, and what beats it?

Off the frontier

No. GPT-5.6 Luna (xhigh) is at least as smart for the same money or less.

Next step up: Gemini 3.7 Flash (low), smarter but dearer.

Deciding

Should you use Solar Pro 3?

Should you use Solar Pro 3?

Only when it fits your setup: GPT-5.6 Luna (xhigh) is at least as smart for the same money or less, so Solar Pro 3 is off the value frontier today.

What is better and cheaper than Solar Pro 3?

GPT-5.6 Luna (xhigh) — at least as smart for the same money or less.

How much does Solar Pro 3 cost?

$0.15/$0.60 in/out per 1M tokens, and $158 to run the full Artificial Analysis Intelligence Index, the honest all-in number for reasoning models.

Is Solar Pro 3 on the Pareto frontier?

No: GPT-5.6 Luna (xhigh) beats it on intelligence, cost, or both.
