Where else you can run GPT 5.6 Terra Pro

The same model is resold by 3 providers we track. The typical one charges 2× what the cheapest does — $4.50 against $2.25 per 1M tokens, blended 3:1. Routing the same workload to a different host is often a bigger saving than switching model.

Third-party listings via models.dev, not rates we verify with each host the way we do first-party pricing. Treat them as a shortlist to check, not a quote — and confirm quantisation, context limits and rate limits before switching, since a cheaper host is not always serving the same thing.
