🤖 A tool that allows you to collect ML models based on a text denoscription

There's an entire agent system inside that automates the entire ML creation cycle - from the idea to the finished solution, without manual fiddling with architecture and pipelines.

How it works:
You formulate the task in ordinary text and provide the data. If necessary, the system extracts the schema itself

Under the hood, a group of AI agents work: one designs the model, the second writes the code, the third evaluates the quality and corrects errors

If there's a lack of data, the system can generate a synthetic dataset for testing

There's support for Ray for parallel model exploration and scaling to cores or clusters

It connects to any cloud or local models via LiteLLM


It's ideal for rapid prototyping and experiments, when it's important to quickly get a working result - get it here.
