Cheapest API setup for email/admin agent running 8 hrs/day?
trying to get realistic numbers here.
my use case is pretty basic: agent handles admin work like identifying relevant emails, sorting/prioritizing, drafting replies, and sending compliant cold outreach. Assume ~8 hours/day of work.
What are people actually PAYING per month for this?
Looking at APIs like:
- MiniMax
- Claude
- Gemini
- DeepSeek
- OpenAI
- GLM / Qwen etc.
Main questions:
- What’s the cheapest API that’s still reliable for boring admin/email tasks?
- Do you pay purely per use/tokens, or are people running monthly plans somewhere?
- For this type of workflow, do you route cheap model for 90% and only use Claude/Sonnet/etc. when it needs reasoning?
- What’s a realistic monthly cost if this runs daily?
- What stack are people actually using in production-ish setups?
Not trying to burn money using frontier models for email triage. Just want the lowest-cost setup that doesn’t hallucinate or loop itself into a token bonfire.
Curious what everyone here is using.
Trying to avoid the classic “cool agent, $400 API bill” situation.
