What the numbers mean

glm-5.3 is roughly 4.1× cheaper on input than gpt-5.6-sol. If your workload passes the quality bar on the cheaper model, that gap compounds across every request; route to gpt-5.6-sol deliberately rather than by default.

Measured intelligence index differs by only 2.7 points, which in practice means the two models are interchangeable on most tasks — pick on price and latency.
