Train with your code as-is
No more performance losses from fitting your working code to a new training API. Wrap your code in a few HTTP routes, deploy it with Synth AI’s built-in tools, and start training. Zero additional infrastructure needed.Real-time observability
Watch your training run as it happens. Live dashboards show trial progress, score distributions, and token spend. No more waiting hours to find out something went wrong.Cost-aware optimization
Sample-efficient optimization algorithms. Built-in budget enforcement and adaptive batch sizing — set a token limit, Synth AI adheres to it.Fast iteration
Parallel evaluation across test cases. Adaptive rate limiting that maximizes throughput without hitting provider limits. Start a run, get results in minutes instead of hours.Multi-language support
Synth AI supports Python, TypeScript, Rust, Go, and Zig.Start training your model
