Hermes model eval for finance business

Prompt

I am a debt advisor, and trying to pick the best models for our hermes agent that assists with deal tracking, email drafts, deal summaries and analyis. so lots of deal context and tool calling in hermes. gpt 5.6 luna has been working well. Minimax m3 is good for agentic stuff but not great personality for analyis or writing. Looking for other cost effective models, why would i use grok 4.5 over luna? any other similarly priced(cheaper models) you recommend?
