An AI safety researcher at Anthropic resigned this week with a stark warning that the "world is in peril," citing concerns about artificial intelligence, bioweapons, and the state of the world. Mrinank Sharma, who shared his resignation letter on X, announced he would be leaving the US firm to pursue writing and poetry, and relocate to the UK. This news comes amid a flurry of activity and concern in the AI world, including advancements in language models and the development of tools to enhance AI capabilities.
Sharma's departure follows the resignation of another researcher from OpenAI, who also expressed worries about the direction of the technology. In his letter, Sharma did not elaborate on the specific threats he perceived, but his decision underscores growing anxieties within the AI community about the potential risks associated with rapid advancements in the field.
Meanwhile, researchers continue to push the boundaries of AI capabilities. Nvidia has developed a new technique called dynamic memory sparsification (DMS) that can reduce the memory costs of large language model reasoning by up to eight times, according to VentureBeat. This method compresses the key value (KV) cache, which is temporary memory LLMs use to process information. Experiments show that DMS enables LLMs to "think" longer and explore more solutions without sacrificing accuracy.
In other AI-related news, a musician who lost his voice to ALS was able to sing again thanks to AI. As reported by MIT Technology Review, the musician, Patrick Darling, was diagnosed with ALS at age 29 and lost the ability to sing. AI technology allowed him to perform on stage with his bandmates again.
Further developments in AI tools include the creation of cloudrouter, a skill for Claude Code/Codex that allows users to spin up cloud VMs and GPUs. This tool, as described on Hacker News, gives AI agents the ability to create cloud sandboxes, run commands, transfer files, and automate browsers.
The convergence of these developments highlights the rapid evolution of AI, encompassing both advancements in capabilities and growing concerns about potential risks. The AI landscape is rapidly changing, with new tools and techniques emerging alongside increasing scrutiny of the technology's impact on society.
