MaestroBillions of Agents, Millions of Models, One AI Execution Model
by ZB Stack
One model that makes every AI model and every AI agent work together on your job, checks every result, and gets it done for a fraction of the tokens.
Build with the best of AI,
for up to 90% less.
One account. One bill. Maestro runs all of it.
-
300+
AI models
The best of every model provider, in one place. The right one on every task.
-
100+
AI agents
Ready to work: code, design, payments, marketing, legal, customer service and more.
-
Up to 90%
less on your AI bill
The same work and the same result, for a fraction of the tokens.
The lab
We build intelligence through collaboration: systems in which many AI models and AI agents reason, act and learn together, and accomplish what no single model can.
The bill
Every agent runs on tokens.
Every piece of AI work is paid for in tokens. A token is a piece of a word. Every question, every answer, every line of code and every picture is tokens in and tokens out, with a bill for each one.
A model thinks. An agent acts. An agent is a model with hands: it can open a file, call a tool, read a contract, send an email, write code and run it. Every company is building agents now, and every agent spends tokens on every task it does. Almost all of them send every task to one big model, at the top price.
- One answers customers.tokens on every answer
- One reads the contracts.tokens on every page
- One writes the code.tokens on every line
- One watches the servers.tokens on every check
Same task.
90% less.
There are millions of models, and each one is best at something. One writes the best plan. One writes the best code. One draws the best pictures. They do not cost the same, and the best model for a task is rarely the priciest one. Put them to work together, each on what it does best, and the same job costs up to 90% less.

The category
Not a model that does the work.
A model that gets the work done.
One job is thousands of tasks. Build a store, and inside it are the spec, the plan, the pictures, the code, the tests and the words for every email. Every one of those tasks has a right model, a right agent and a right price. Making them all work together, thousands of times a day, is a job of its own. It needs a model of its own.

We built the first one. Its name is Maestro.
Maestro
A maestro plays no instrument.
A maestro in front of an orchestra plays nothing. The maestro knows which instrument to call on, and when, and hears when a note is wrong. Maestro does the same with AI. It knows what every model and every agent does best, what each one costs and how fast it runs, and it makes them work together on one job.
- 01
Break down.
The job becomes tasks, each with a clear result to reach.
- 02
Route.
Each task goes to the model or the agent that does it best, yours, ours or anyone’s, on the cloud that runs it for the least.
- 03
Check.
Every result is tested or reviewed by a model that did not produce it. A failed check sends that one task, and only that task, up to a stronger model.
- 04
Assemble.
The pieces come together into one result, and every model and agent gets what it needs to know from the one before it.
- 05
Learn.
Maestro remembers which route won, and uses a new model the day it becomes the best choice. Better routes every job, and the bill goes down on its own.
Who it is for
One model.
Three kinds of builder.
-
Startups.
Bring an idea. A team of AI agents turns it into a business, working together: the plan, the product, the pages, the code, the answers to customers. Maestro gets every task done by the right model, for the price of the cheapest one that does it well.
For startups -
Enterprises.
You already have agents, models and a token bill. Maestro makes the agents you have and the models you choose work together on every job, checks every result, and puts every task on record. One bill for all of it.
For enterprises -
Nations.
A nation’s own AI, with the best of every model. Your own models and your own agents where you want them, working together with the best model in the world for every other task.
For nations
