# POSE: Phase I: OpenTrustLLM: An Open-Source Ecosystem for Trustworthiness in Large Language Models

> **NSF 01002526DB NSF RESEARCH & RELATED ACTIVIT** · Lehigh University (PA) · $300,000

## Abstract

This Pathways to Enable Open-Source Ecosystems (POSE) project involves the creation of an open, community-driven framework to evaluate and enhance the trustworthiness of large language models (LLMs). Large language models are increasingly utilized in sectors such as healthcare, finance, education, and national security, yet concerns about their reliability, safety, and transparency remain significant. This project establishes a collaborative ecosystem that enables stakeholders to assess trustworthiness using open standards and transparent processes. By promoting confidence in artificial intelligence technologies, this project advances national health, economic growth, and benefits all Americans. The effort contributes to scientific and technological understanding by promoting rigorous evaluation practices and facilitating education around trustworthy artificial intelligence development. The project strengthens United States leadership in artificial intelligence safety and reliability, benefiting academic researchers, industry professionals, government agencies, and the broader public through more dependable artificial intelligence applications.

This Pathways to Enable Open-Source Ecosystems (POSE) project revises an existing trustworthiness evaluation platform into a sustainable open-source ecosystem named OpenTrustLLM. The project addresses the challenge of fragmented trustworthiness evaluation methods by constructing a unified infrastructure with distributed community go
