Red-team and evaluate AI agents before they reach production
Adversarial evaluation of agents to surface unsafe, non-compliant or unreliable behaviour before they run against real users and real money.
Measure and track how much fine-tuning private models with LangTrain improves accuracy for your specific domain.
Verify that agent responses are repeatable and reliable enough for regulated workflows such as clinical, lending or claims decisions.
Evaluate agents that work across text, voice, vision and other modalities rather than text alone.

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.
