The program provides researchers with the skills, knowledge, and experience needed to leverage Jetstream2 in their AI-based research projects.

The program includes project consulting, training, priority access to high-end GPUs, and community contributions.

"This fellowship has been instrumental in accelerating both the technical and instructional components of my project. The flexibility and power of Jetstream2 allowed me to move rapidly from benchmarking to infrastructure design, while the support from the broader NAIRR and JS2 communities helped me think more ambitiously about how to translate research workflows into reproducible, scalable learning experiences. I’m especially excited about how this work will impact students through the upcoming NAIRR Classroom Pilot and grateful for the opportunity to build something that bridges research, education, and responsible AI development." - 2025 NAIRR AI Fellow

Best apply by date is October 1, 2025.

Jetstream2 launches annual survey

The Jetstream2 Annual User Assessment has been sent to a select number of Jetstream2 community members.

Feedback is vital to the evolution of this important resource, so we ask for those who received it to please participate in the 2025 Jetstream2 User Satisfaction Survey, which aims to assess community members’ needs and current levels of satisfaction with Jetstream2 and its associated services.

This annual survey is a Qualtrics form that was sent via email fromqemailserver.com. In the event you haven't seen the survey in your inbox, please check your junk, spam, or trash email folders.

Jetstream2 announcements and system updates

The latest news, updates, and announcements from the Jetstream2 team. 

Jetstream2 August Maintenance

On August 5, 2025, Jetstream2 staff will be retiring the g3.small flavor during the August GPU Maintenance window from 7:00 a.m. to 7:00 p.m. Eastern Time. We will also perform routine infrastructure maintenance on systems that host all partial-GPU flavors (g3.small, g3.medium, and g3.large).

Jetstream2 large language model (LLM) inference service updates

We’re excited to announce that 191 ACCESS community members have utilized the web user interface (UI) to access the new inference service on Jetstream2. Since its release in April 2025, we have continued to develop and improve upon the initial service to keep up with accelerated developments and evolving community needs. 

Review all the inference service updates

 

CACAO interface updates

CACAO, one of the cloud-native user interfaces on Jetstream2, offers our users a platform to deploy and share complex research software stacks using Terraform and Ansible. The CACAO catalog currently includes numerous templates, ranging from creating virtual SLURM clusters ("Magic Castle" by the Digital Research Alliance) to configuring JupyterHubs for courses or teams.
