Advancing Artificial Intelligence (AI) Agent Ecosystems through the National Science Foundation Pathways to Enable Secure Open-Source Ecosystems (NSF PESOSE) Program Encourages NSF Pathways to Enable Secure Open-Source Ecosystems (NSF PESOSE) proposals that focus on the protocols enabling AI agent ecosystems.
Encourages NSF Pathways to Enable Secure Open-Source Ecosystems (NSF PESOSE) proposals that focus on the protocols enabling AI agent ecosystems. The U.S. National Science Foundation (NSF) encourages proposals to the Pathways to Enable Secure Open-Source Ecosystems (PESOSE) program that focus on protocols enabling AI agent ecosystems.
The PESOSE program strengthens open-source ecosystems that produce publicly accessible, modifiable, and shareable software and hardware, models and specifications, languages and measures for security and cybersecurity of artificial intelligence (AI) models and systems, metrology, data tools and benchmarking tools.
These open ecosystems drive innovation across AI, cloud computing, finance, healthcare, education, manufacturing, mobility, and national security. PESOSE supports the maturation of the organizations that manage open-source ecosystems by helping them distribute development and grow broad user and contributor communities across academia, industry, and government.
The program also advances security and privacy by addressing vulnerabilities that affect how open ecosystems evolve. AI agent protocol ecosystems AI agents are moving beyond simple chat interfaces. They can operate for long periods, write and debug code, search databases, manage email and calendars, buy goods, and operate laboratory equipment.
These capabilities rely on open interfaces and shared standards that allow agents to communicate with tools, data sources, and each other. An AI agent ecosystem is a network of autonomous agents that communicate, coordinate, and work together using common protocols. These protocols let agents - built by different organizations or using different frameworks - smoothly share data, and perform tasks across different environments.
They are essential for scalable, secure, and reproducible AI systems. PESOSE and AI agent ecosystems The U.S. has a long history of advancing open technology ecosystems and their enabling protocols.
For example, early investments by the Defense Advanced Research Projects Agency (DARPA) and NSF enabled the Transmission Control Protocol/Internet Protocol (TCP/IP) which became the industry standard for addressing, transmitting, and routing data across interconnected networks. Today TCP/IP is the backbone of the Internet.
This Dear Colleague Letter (DCL) highlights NSF’s interest in PESOSE proposals that similarly advance the protocols for AI agent ecosystems, strengthen open‑source foundations and support growth across sectors. PESOSE welcomes proposals that advance one or more of the following: Interoperability. Develop open standards so agents can work across platforms and organizations without custom connectors.
Scalability. Create architectures that support large networks of agents, tools, and services while keeping integration simple. Cross-domain data classification mapping, Role- and attribute-based access control enforcement, Secure, policy-compliant communication channels, Robust authentication and fine-grained authorization, End-to-end auditability, and Formally specified, safe message formats.
Open Science Applications. Demonstrate and evaluate security features in AI ecosystem protocols that enable open science. Partnerships.
Build collaborations among academic, nonprofit, industry, and government partners to accelerate appropriate adoption. Education and Training. Expand training for students and postdoctoral researchers to contribute to AI agent ecosystems, including security and reliability.
NSF will give strong consideration to proposals that address these priorities. Research must remain unclassified and publicly releasable. When responding to this DCL, please title your proposal: “PESOSE / AI: Track #: (title)”.
Proposals must follow the requirements in the NSF Proposal & Award Policies & Procedures Guide (PAPPG) and the NSF PESOSE solicitation. NSF will evaluate proposals submitted in response to this DCL based on their alignment with the goals above. For details, consult the full PESOSE solicitation and/or website.

This program supports research to unlock the value of datasets for AI-enabled scientific discovery. It focuses on the ideas, talent, and infrastructure that strengthen U. S.
RET Sites close October 14, 2026 — about nine awards from $5.8 million, capped at $600,000 over three years, with a PI eligibility rule that disqualifies most of the people who write outreach proposals. RET Supplements reach the same money for $15,000 a teacher and are not a competition.
Read articleNSF 26-523 folds 12 core physics programs and three cross-cutting ones into a single solicitation with $180 million and roughly 300 awards. Proposals are accepted anytime, but AMO-Experiment and Gravitational Physics still target November 25 and QIS targets December 8. Cost sharing is prohibited, indirect cost rates are now a tiebreaker, and NSF reserves the right to phase out long-duration efforts after comparative review.
Read articleFuture CoRe (NSF 25-543) advertises $280 million and 400 to 600 awards across 11 programs, with a September 10, 2026 target date. The directorate behind it is running 43 percent below its own four-year average, $1 billion of NSF's budget is locked in a central account, and the two-proposal cap is enforced with no exceptions. Here is how to read the gap between what the solicitation promises and what the directorate is actually paying for.
