Quick Decision

Verdict

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

For a 1M input token plus 500K output token workload, the estimated API cost is $20 for GPT Chat Latest and $105 for GPT-5.2 Pro.

Best Fit

Choose GPT Chat Latest when you care most about lower input-token price, and lower output-token price.

Choose GPT-5.2 Pro when its provider, model quality, latency, or availability is more important than the numeric price/context winner.
