How It Works
Fine-tuning in minutes, not months
From plain English description to production-ready API in four simple steps. No ML expertise or data preparation required.
Step 01
Describe your goal
Write what you want the model to do, how it should respond, and what it should avoid. Use natural language — no technical jargon required.
- Define the model's personality and tone
- Specify rules and constraints
- List edge cases to handle
- Describe the expected output format
I need a customer support bot that: - Uses a friendly, professional tone - Escalates to humans for refunds > $100 - Never shares internal pricing data - Responds in the customer's language
Step 02
Agents go to work
Our AI agents take your description and automatically generate training data, then run fine-tuning jobs across multiple providers in parallel.
- 200+ synthetic training examples generated
- Parallel training on OpenAI, Together AI, Replicate
- Real-time progress updates via WebSocket
- Multiple model variations tested simultaneously

Step 03
Review results
Compare outputs side by side. Our LLM-as-judge evaluation scores each model on accuracy, tone, and rule compliance.
- Side-by-side output comparison
- Automated scoring on multiple criteria
- Test with your own custom inputs
- Detailed failure case analysis
