Launch
Making developing and maintaining a SOTA AI system simpler.
Synth logs agent activity, identifies failure modes, and fine-tunes base models used by the agent to improve performance. It provides a three-step workflow—summarize logs, flag issues, and address them with fine-tuned models and suggested code changes—targeting teams building multi-step AI agent systems.
