• Check your balance (prod backend):

- Start local services (tracing DB + env service):
```bash
uvx --from synth-ai synth-ai serve --force

• Explore examples:
  • Evals Demo
  • Rejection Training (SFT)

​

What you can do

• Configure simple and modular evals and metrics for agent runs
• Run inference on and finetune Open models via Synth endpoints to iterate on hypotheses
• Inspect every LLM/tool call with structured tracing
• And more

​

Jump in

• Evals Demo: compare models and export datasets
• Rejection Training: generate → filter → train → run
• On-Policy RL: deploy task app → mint env key → check → run RL

​

API

• HTTP endpoints (inference, files, SFT, models, balance):
  • See the concise spec: HTTP API Reference
