Quick Decision

Verdict

GLM 4.6V has the lower input price; GLM 4.6V has the lower output price; both models report the same context window. For the 1M input plus 500K output sample, GLM 4.6V is cheaper for the standard workload.

For a 1M input token plus 500K output token workload, the estimated API cost is $1.6 for Aion-2.0 and $0.75 for GLM 4.6V.

Best Fit

Choose Aion-2.0 when its provider, model quality, latency, or availability is more important than the numeric price/context winner.

Choose GLM 4.6V when you care most about lower input-token price, and lower output-token price.
