I haven't found a model at the price point of GPT-4o mini that is as capable. Based on the hype surrounding Llama 3.3 70B, it might be that one though. On Deepinfra, input tokens are more expensive, but the output token is cheaper so I would say they are probably equivalent in price.

Also, best bang for the buck is very subjective, since one person might need it to work for one use case vs somebody else, who needs it for more.
