When GPT-4o mini is the right call
OpenAI's small, low-cost model for high-volume, latency-sensitive work.
On blended price, GPT-4o mini is mid-pack: 1 compared here are cheaper and 5 cost more. Whether its rate is worth paying comes down to fit. A model that resolves a task in fewer attempts or shorter prompts can come out ahead of a cheaper one that needs retries, so price it on your own evaluation set and token mix rather than the per-million rate alone.

Questions & answers
- How much does GPT-4o mini cost?
- GPT-4o mini is $0.15 per million input tokens and $0.60 per million output tokens, at public list price (2026-06). At a typical 3:1 input-to-output mix that blends to about $0.26 per million tokens.
- What is a cheaper alternative to GPT-4o mini?
- The cheapest option compared here is Gemini 1.5 Flash at about $0.13 per million blended, roughly 50% less than GPT-4o mini. Whether it fits depends on your task: a cheaper model that needs retries or longer prompts can cost more in practice.
- How much does GPT-4o mini cost to run an AI agent per month?
- On a representative agent workload (2,000 requests a day, 3 tool calls, RAG on), GPT-4o mini comes to about $274 a month. That includes the agentic context tax, where every tool call re-sends the conversation and you pay for it again. Your real figure depends on volume and tokens, so run it in the calculator.
A model's list price is not its bill.
Prompt caching, context trimming, and the right tier per task usually move an LLM bill more than the model choice does. Book a call, or leave your email and I'll reach out.
