Well I think there's many cheaper models in terms of bang for buck currently per token and intelligence than gpt4o. Other than OpenAI having very high rate limits and throughout available without a contract done with sales, I don't see much reason to use it currently instead of sonnet 3.5 or 3.7, or Google's Flash 2.0

Perhaps their training cost and their current inference cost is higher, but what you get as a customer is a more expensive product for what it is, IMO.
