Track, evaluate, and ship AI models and agents in one connected environment.
Log metrics, losses, and media from training runs and compare them side by side in interactive charts to spot what actually improves your model.
Run automated hyperparameter sweeps and visualize parameter importance so you can converge on better configurations faster.
Version datasets and model artifacts, track lineage, and promote models through a registry from training to production.
Build, log, and evaluate LLM prompts and applications, with tracing and evaluation tools grouped under an LLMOps workflow.
Simulate hundreds of realistic user conversations to test and train your LLM app
Deploy diverse synthetic users with varied intents, tones, goals and interaction styles to mirror real-world behavior.
Run hundreds or thousands of multi-turn conversations in minutes instead of scripting them by hand.
Export evaluation sets with judge labels to feed your existing evaluation tooling and catch regressions.
Produce preference pairs for DPO or reward models and critique-and-revise triples for SFT as clean JSONL.
