More and more public services—such as affordable housing, public school matching and child welfare—are relying on algorithms to make decisions and allocate resources. So far, much of the work that has gone into designing these systems has focused on workers’ experiences using them or communities’ perceptions of them.More and more public services—such as affordable housing, public school matching and child welfare—are relying on algorithms to make decisions and allocate resources.

Open-source small language models (SLMs) can provide conversational responses that are similar to resource-intensive, proprietary large language models (LLMs) such as OpenAI’s ChatGPT, but at a lower cost, researchers at the University of Michigan have found. Their findings are published on the arXiv preprint server.Open-source small language models (SLMs) can provide conversational responses that are similar to resource-intensive, proprietary large language models (LLMs) such as OpenAI’s ChatGPT, but at a lower cost, researchers at the University of Michigan have found.

Generative artificial intelligence (AI) tools are used to create text, images and videos, impacting the way society consumes and produces online content. As that technology continues to evolve, it is becoming increasingly difficult to tell the difference between AI-generated and human-generated content.Generative artificial intelligence (AI) tools are used to create text, images and videos, impacting the way society consumes and produces online content.

Metal coins may be just about the oldest medium of exchange still in use today, but ensuring their worth requires some of the most state-of-the-art technology available. Counterfeit coins remain a threat to global currencies, with malicious actors flooding markets with fakes. European police broke up a Spain-based criminal ring in late April, demonstrating the issue’s ongoing urgency.Metal coins may be just about the oldest medium of exchange still in use today, but ensuring their worth requires some of the most state-of-the-art technology available.
