How much does an AI agent cost? An AI agent costs three things: the software or platform it runs on, the implementation that connects it to your business, and the AI usage it consumes every month. On official pages checked on October 28, 2026, Salesforce lists Agentforce Max Edition from $550 per user per month and Botpress lists its Team plan at $750 a month billed annually or $939 billed monthly.
OpenAI lists its gpt-6-astra model at $10 per million input tokens and $50 per million output tokens at standard speed for prompts of up to 272K input tokens. Tokens are the pieces of text the model reads (input) and writes (output), and a prompt is everything the agent sends the model in one request.
With MAGIA Solo, Catalizadora builds your AI agent in 15 days: it answers WhatsApp day and night, books appointments and shares payment links, and everything stays in your name. Below is what each cost covers, so you can model your own number.
AI agent software cost grows with your users, conversations and actions
Business AI agent platforms rent you the agent and bill it every month. Salesforce's Agentforce pricing page lists Max Edition from $550 per user per month, for its Sales, Service, Sales/Service and Industries editions, with the Agentforce add-on and 2.75 million Flex Credits per organization per year included. Past that, Salesforce sells Flex Credits at $500 per 100,000 to pay per action, and a standard Agentforce action uses 20 credits, which by our math is $0.10 per action.
Salesforce also lists a per-conversation option at $2 per conversation for customer-facing agents. The Agentforce pricing page carries this note: "This page is provided for information purposes only and is subject to change."
Botpress lists its Team plan at $750 a month billed annually or $939 billed monthly, with 1,500 conversations a month and $150 of AI usage included. Extra conversations come in packs of 100 for $50, and its Enterprise plan has custom pricing.
With a platform, the bill follows your headcount, your conversations and your actions for as long as you stay subscribed. With MAGIA Solo, the build is paid once, monthly operations are paid at cost in your name, and what we build is yours.
How much does an AI agent cost to run each month: the API bills it per million tokens
The API is the paid connection your agent uses to call an AI model, and model makers bill it per million tokens, the pieces of text the model reads (input) and writes (output). Anthropic says that, with the tokenizer its current models use to split text, 1 million tokens is roughly 555,000 words.
If you were pricing an autonomous agent on GPT-4, that model is gone: OpenAI's deprecations page says access to gpt-4 was shut down on October 23, 2026. On OpenAI's pricing page, gpt-6-astra costs $10 per million input tokens and $50 per million output tokens at standard speed for prompts of up to 272K input tokens, and longer prompts and its Fast and Ultrafast modes cost more, for example $120 per million input tokens and $450 per million output tokens on Ultrafast with prompts over 272K tokens. Anthropic lists Claude Fable 5.1, built "for demanding reasoning and long-horizon agentic work" (hard problems an agent solves in many steps on its own), at a base price of $10 per million input tokens and $50 per million output tokens, matching the gpt-6-astra standard rate.
By our own math, at $10 per million input tokens and $50 per million output tokens, every 10 million input tokens plus 1 million output tokens cost $150 on gpt-6-astra at standard speed for prompts of up to 272K input tokens, or on Claude Fable 5.1 at its base price. Your real number depends on how many conversations the agent handles and how long they run. For a closer look at models, see how to choose the best autonomous AI agent for business.
If your agent answers on WhatsApp, Meta adds its own fee. Meta charges per delivered message, at a rate that depends on the message category and the country of the number that receives it. Since October 1, 2026, each business phone number gets 1,000 free delivered service messages a month, and Meta charges from the 1,001st delivered service message.
Meta's rates by country and a sample month are in our guide to WhatsApp chatbot pricing.
AI agent implementation cost is the work of connecting and testing it
Implementation is the build: connecting the agent to your systems, teaching it your information and testing it before customers see it. Clutch's AI development pricing page, updated September 21, 2026, says AI development projects reviewed on Clutch range from $10,000 to $49,999, in U.S. dollars, based on reviews from verified AI development clients. The same page puts the average project at $120,594.55, based on reviews on Clutch, and the typical timeline at 10 months, so budgets can run above that range.
OpenAI's guide to building agents explains where that work goes. Tools connect the agent to the systems underneath, evals (test sets that measure how well the agent does the job) set a performance baseline, and sensitive, irreversible or high-stakes actions, such as making payments, should trigger human oversight until confidence in the agent's reliability grows.
MAGIA Solo covers connecting, training and testing inside its 15 days. We train the assistant on your real services, your prices and the way you talk, then connect everything and test it with real cases until it answers the way it should. When a query gets sensitive or falls outside its scope, the assistant hands it to you instead of improvising.
MAGIA Solo puts a working AI agent in your name in 15 days
When you work alone, every unanswered message is a sale going cold. MAGIA Solo is built for professionals and small businesses: in 15 days we hand you a system that answers, books and gets you paid. Its assistant handles WhatsApp day and night, with your voice and your prices.
The assistant offers your slots, books them on your calendar, sends the reminder and shares a payment link right in the chat. You also get your professional page and a panel with clients, appointments and sales on a single screen.
MAGIA Solo is a one-time payment of 4,500 USD, with training and 6 months by your side included. Monthly operations (keeping the system online and the AI that answers) are paid at cost, directly to the providers and in your name. If you want your system to stay hosted and operated by Catalizadora, that requires an active plan, from 99 USD a month.
Code, data, domain and accounts are in your name from day one. Catalizadora has built more than 500 projects, served more than 100,000 clients with AI and has systems running in 5 countries, as the MAGIA Solo page shows.
