AI Briefing
Today's AI landscape is split between humbling reality checks and bold power moves. A new benchmark just exposed that every frontier model, including GPT-5.4 and Claude Opus 4.6, scores below 1% on tasks humans ace effortlessly, while Mistral quietly dropped an open-source voice model that can clone your voice from three seconds of audio. Meanwhile, both the White House and EU are racing to shape the rules of the AI game before it gets away from them.

ARC-AGI-3 Humbles Every Frontier AI Model, Scoring Below 1% Where Humans Get 100%
The ARC Prize Foundation launched ARC-AGI-3 on March 25, a new interactive benchmark that ditches static puzzles for turn-based games with no instructions and no stated goals. The results are striking: humans solve 100% of the environments while the best AI (Gemini 3.1 Pro) managed just 0.37%. GPT-5.4, Claude Opus 4.6, and Grok 4.2 all scored near zero. This benchmark measures something fundamentally different from previous tests, specifically the ability to explore, adapt, and learn on the fly, and it reveals a massive gap between pattern-matching at scale and genuine flexible reasoning.

Mistral Drops Voxtral TTS: A 4B-Parameter Open-Source Voice Model That Clones From 3 Seconds of Audio
Mistral released Voxtral TTS on March 26, a lightweight 4-billion-parameter text-to-speech model that supports nine languages and can clone a voice from as little as three seconds of audio. The model achieves a time-to-first-audio of just 90 milliseconds and runs on consumer hardware, including laptops and mid-range GPUs. Available on Hugging Face under a Creative Commons license, it puts Mistral in direct competition with ElevenLabs and OpenAI's voice offerings, but with a fully open-weight approach that lets developers self-host and customize.

White House Unveils AI Policy Framework, Seeks to Preempt State-Level AI Laws
The Trump administration released a National Policy Framework for Artificial Intelligence on March 20, urging Congress to create federal AI legislation that would override state-level AI regulations. The framework takes a deliberately light-touch approach: no new federal AI agency, sector-specific oversight through existing regulators, and broad preemption of state laws deemed to impose "undue burdens" on AI development. It also takes a position on copyright, stating that training on copyrighted material doesn't violate copyright law, while recommending courts settle specific disputes.

EU Council Agrees to Delay High-Risk AI Rules, Adds Ban on AI-Generated Abuse Content
On March 13, the EU Council agreed its negotiating position on streamlining the AI Act, pushing back deadlines for high-risk AI system compliance to December 2027 for standalone systems and August 2028 for products with embedded AI. The delay gives companies more time to prepare, but the Council also added teeth: a new prohibition on using AI to generate non-consensual sexual content and child abuse material. The position now heads to negotiations with the European Parliament, setting the stage for what could be the final shape of EU AI regulation.

Perplexity Launches 'Personal Computer,' an Always-On AI Agent Running on Your Mac Mini
Perplexity announced Personal Computer on March 11, a product that turns a dedicated Mac mini into an always-on AI agent that works across your local files, apps, and sessions 24/7. Instead of running AI through a browser tab, it puts an agent directly on your machine with access to your local system. Every sensitive action requires approval, every action is logged, and there's a kill switch. It is the clearest signal yet that AI companies see the future not in chat windows but in persistent agents that live on your hardware and act as a digital proxy.
