Cost & ROI hub/Agent pricing
How much does an AI agent cost to build and run?
Two products share the name. A SaaS chatbot rents you answers. A production agent reads and writes your systems, and someone has to operate it after launch. Kemeny Studio quotes the second one at a fixed price per stage.
The short answer
In the LatAm market in 2026, a custom AI agent on one workflow typically costs $20,000 to $80,000 USD to build over 4 to 6 weeks, plus $2,000 to $8,000 USD per month to operate. A no-code chatbot is $50 to $500 per month and rarely moves an operating metric. Figures are market ranges; Kemeny Studio quotes a fixed fee after a 10-day audit.
What are you actually buying when you buy an “AI agent”?
A chatbot answers from a script or a knowledge base. An agent takes actions with consequences: it quotes, files, matches, or flags, using your CRM, ERP, or inbox. The the chatbot cost calculator is the honest comparison when the job is conversations; this page is the comparison when the job is a back-office or sales workflow.
Kemeny Studio builds the second kind. The flagship packaged version is Comercial AI, a sales agent on your own WhatsApp number. Everything else is scoped as one workflow after the audit.
What does it cost to build versus run an AI agent?
The build is the 4-to-6-week window: integrations, evaluation on your data, and a production deploy. The LatAm market sits in the $20,000–$80,000 band for one workflow; US consultancies often quote $150,000+ for the same shape. The run is the part most quotes skip: model APIs, monitoring, evaluation, prompt drift, and engineering time when the model vendor ships a breaking change. Plan $2,000–$8,000 per month per agent.
Token cost is the smallest slice of the run. Price it on the the LLM API cost calculator so it stops dominating the meeting, then budget the rest. The full stack is on the AI implementation cost guide.
| Line | SaaS chatbot | Custom agent (LatAm market) |
|---|---|---|
| To start | $50–$500 / month | $20,000–$80,000 build, 4–6 weeks |
| To keep running | Inside the subscription, plus per-conversation fees | $2,000–$8,000 / month managed |
| Your data | Lives in the vendor | Lives in systems you control |
| Cost as volume grows | Rises with seats and messages | Flat operation fee |
Should you buy a platform or build an AI agent?
Buy when the problem is standard and the vendor’s connectors reach your systems. Build when the agent must execute your cycle, keep data in systems you own, or when per-conversation fees will overtake a flat operation fee at your volume. The how to choose an AI vendor page is the eight questions to ask before you sign either way.
Kemeny Studio is an AI and software factory, not a seat licence. The the AI Sprint takes a validated workflow to production in four weeks. If a packaged tool already resolves more than 60% of the work, we will tell you to keep it.

FAQ
Cost questions, answered
How much does a custom AI agent cost in Mexico or Chile?+
The LatAm market typically quotes $20,000 to $80,000 USD to build one production workflow, plus $2,000 to $8,000 USD per month to operate it. The same shape from a US firm is often $150,000+. Kemeny Studio operates from Mexico City and Santiago and quotes a fixed price after a 10-day audit, not a range on this page.
Is the LLM API the main cost of an AI agent?+
Almost never. Tokens are usually a small fraction of a production agent. Integration, evaluation, and day-two operation dominate. Price the tokens with the LLM calculator so the conversation can move to the lines that actually move the total.
How much does it cost to keep an AI agent in production?+
Plan $2,000 to $8,000 USD per month per agent in the LatAm market: model APIs, infrastructure, monitoring, evaluation, and the engineering time to absorb model updates. An unbudgeted operation line is the most common reason agents die after launch.
Can I start with a cheap chatbot and upgrade later?+
Yes, if the chatbot already resolves the majority of the work. You are not building equity in the vendor’s prompts, so the later custom build still starts near zero. That can still be the right sequence when you need a yes/no on demand before committing to a 4-week sprint.
Does Kemeny Studio sell AI agents by the seat?+
No. There is no seat licence and no per-conversation fee. The audit is a fixed fee, the build is a fixed-scope quote, and operation is a flat monthly fee. That is the engagement model, not a catalogue price list.
