Researchers in Lausanne developed an open medical model in collaboration with the Red Cross, focusing on humanitarian applications.

The German research consortium has released Soofi S, an open-source language model with 30 billion parameters, trained on Deutsche Telekom's AI cloud infrastructure. The model features a hybrid architecture that activates only 3.2 of its 31.6 billion parameters per token, maintaining processing speed with long inputs and excelling in both English and German benchmarks.

Investment in free, open-source AI is encouraged for governments, companies, and nonprofits to promote accessibility and innovation. Open-source AI can enhance collaboration and reduce reliance on proprietary technologies.

The Claude Design System prompt is a reverse-engineered system prompt and skill library that transforms a large language model (LLM) into an opinionated, accessibility-aware design collaborator. It is open source and MIT licensed, compatible with any LLM that supports system prompts, and addresses the limitations of typical design assistant prompts by avoiding generic outputs.

Anthropic CEO Dario Amodei warned lawmakers that open-source AI is becoming increasingly dangerous. He stated that once powerful models are released openly, companies cannot effectively monitor misuse, revoke access, or update safety measures.
