Jetstream2 Introduces LLM Inference Service

The ACCESS resource Jetstream2 at Indiana University recently unveiled a Large Language Model (LLM) inference service tailored to the system’s users. The service provides access to advanced open-weight LLMs through two primary interfaces: a browser-based chat interface via Open WebUI similar to ChatGPT; and OpenAI-compatible inference APIs for seamless integration into projects and applications. For more information see Indiana University’s recent news release.

SC25 Content Deadlines

While the deadline for Paper submissions for SC25 has passed, there are still a number of opportunities to participate in the conference. The next deadline is April 28 for Tutorials and Panels submissions. Find all the open opportunities here.
