What it is
What you pay for when you buy a custom AI agent
A custom AI agent has two kinds of cost. The build and upkeep cost is engineering time: designing the agent, connecting it to your tools and data, testing it on real cases and fixing it when a model, an API or your process changes. The running cost is model usage and hosting, billed by the providers you use and driven by how many runs the agent makes.
AY Automate prices the engineering side as one monthly partnership, from $3K a month. There is no per-project quote, because most agents keep changing after launch and a fixed scope stops covering the work within weeks. You can cancel anytime, and a 90-day replacement guarantee applies to the engineer on your account.
Running cost depends on your volume and the model you pick, so we do not quote a fixed number for it. Our free AI agent cost calculator estimates monthly cost per run from your own inputs, and the free audit turns your real volumes into the same estimate before you commit.
The comparison most teams make is against hiring. On our hire AI developers page, a US in-house AI engineer is shown at $150,000 or more a year in salary, about $30,000 in employer taxes and benefits and $20,000 to $40,000 in recruiting cost. A partnership from $3K a month has none of those extras.

When NOT to use this
- You need a single FAQ chatbot with no actions. A managed chatbot product is cheaper.
- You want a fixed-price, one-off build with no upkeep. We work as an ongoing partnership, not per project.
- You have no workflow defined yet. Write down the job the agent should do first, or start with the free audit.

FAQ
Custom AI agent cost questions
How much does it cost to build a custom AI agent?+
AY Automate builds custom AI agents from $3K a month as an ongoing partnership. There is no per-project quote. The price covers an engineer on your account, the first agent in production and monitoring and maintenance afterwards. Cancel anytime, with a 90-day replacement guarantee. Model usage and hosting are billed separately by the providers you choose.
How much does a custom AI agent cost for a SaaS company?+
The same: AY Automate builds custom AI agents for SaaS companies from $3K a month, cancel anytime. SaaS agents usually start with support triage, onboarding or sales research, and they need upkeep as the product changes, which the monthly partnership covers. Running cost depends on your ticket or account volume, and the free AI agent cost calculator estimates it from your inputs.
How much does fractional AI engineering cost?+
AY Automate places fractional and embedded AI engineers from $3K a month, with no recruitment fee and no employer taxes on top, and a 90-day replacement guarantee. Placement usually takes 2 to 4 weeks. For comparison, our hiring page shows a US in-house AI engineer at $150,000 or more a year before taxes, benefits and recruiting.
What drives the cost of an AI agent?+
Three things. How many systems the agent has to read from and write to, how risky its actions are, which decides how much testing and approval it needs, and how often it runs, which drives model usage. A narrow agent on one system is quick to set up. An agent across several systems with sensitive actions takes longer and needs more upkeep.
What does it cost to run an AI agent each month?+
Running cost is model usage plus hosting, and it scales with the number of runs and the model you choose. We do not quote one number for it because it depends on your volume. The free AI agent cost calculator estimates monthly cost per run, and the audit call works it out from your real volumes.
Is a custom AI agent cheaper than hiring an AI engineer?+
For most teams with one or two agents, yes. Our hiring page shows a US in-house AI engineer at $150,000 or more a year, about $30,000 in employer taxes and benefits and $20,000 to $40,000 to recruit. AY Automate starts from $3K a month with none of those extras. Hiring in-house makes sense once you have enough agent work to keep a full-time engineer busy.
Do you charge per project?+
No. AY Automate works as an ongoing partnership from $3K a month, not per project. Agents change after launch as models, APIs and processes change, so the upkeep is part of the price instead of a new quote each time.
