Dynamic AI agent testing for the real world with Collinear Simulations and Together Evals

Together AI · 9 months ago · 35

Collinear Simulations and Together Evals have integrated their products to enable testing of AI agents with dynamic, persona-driven interactions that simulate realistic human behavior across multiple traits like impatience and skepticism. The TraitMix system generates hundreds of multi-turn conversations using a model-agnostic method representing controllable user traits, which can then be evaluated automatically using Together's LLM-as-a-judge approach for metrics on helpfulness, safety, and factuality. This allows developers to identify how their agents perform under human variability and feed evaluation insights back into retraining and improvement workflows.
