When implementing small language models in business environments, cost optimization becomes crucial. For input-heavy applications, GPT-4o-mini offers significant advantages with its $0.15/1M input token pricing. However, if your application generates substantial output, Hermes 3 might be more cost-effective with its $0.30/1M output token rate.
