DEEPMIND'S APPROACH TO AGI SAFETY

Google DeepMind outlines its perspective on building safe and secure artificial general intelligence, emphasizing oversight and technical safeguards as AGI capabilities progress.

OPENAI JUST MADE ITS FIRST CYBERSECURITY INVESTMENT

OpenAI invested in Adaptive Security, a startup using AI to simulate and train employees against social engineering hacks. Adaptive Security secured $43M in Series A funding, with plans to bolster its platform amid growing AI threats. Co-founded by veteran entrepreneur Brian Long, the startup has quickly amassed over 100 clients since launching in 2023.

OPENAI NONPROFIT GUIDANCE COMMISSION

OpenAI is forming a new expert commission to shape how its philanthropic arm supports communities using AI, aiming to align AI innovation with real-world nonprofit needs.

ARTICULATED KINEMATICS DISTILLATION FROM VIDEO DIFFUSION MODELS

This work introduces Articulated Kinematics Distillation (AKD), a framework that leverages skeleton-based animation and generative diffusion models to produce high-fidelity, physically plausible character motions with reduced complexity. It ensures structural consistency and outperforms existing methods in 3D coherence and expressive motion quality by using Score Distillation Sampling to guide joint-level control.

ENHANCED LORA-BASED FINE TUNING

MetaLoRA introduces dynamic parameter generation using meta-learning principles, enhancing the flexibility and task-awareness of LoRA-based fine-tuning strategies.

BACKDOOR ATTACKS IN CLIP

CLIP models are highly vulnerable to poisoning backdoor attacks, achieving nearly 100% attack success with minimal poisoned data. An efficient detection method is to use local outlier detection to uncover unintentional backdoors in existing datasets.

LARGE SMALL NET

A new family of lightweight vision models inspired by the dynamic heteroscale capability of the human visual system, i.e., "See Large, Focus Small". LSNet achieves state-of-the-art performance and efficiency trade-offs across various vision tasks. It introduces a new type of convolution kernel.

PPLX CUDA KERNELS

Perplexity has released some of its MoE kernels, which outperform DeepSeek at scale while being slightly more flexible and less opinionated about the MoE architecture.

HATEBENCH FOR EVALUATING HATE SPEECH

HateBench provides a framework for evaluating hate speech detection models on LLM-generated content along with a manually annotated dataset and code for analyzing adversarial and stealthy hate campaigns.

ZONOS TTS

A compelling Apache 2.0 model for speech generation and voice cloning. It has multi language support and expressive real time generation.

HUGGING FACE'S AI AGENTS COURSE

Hugging Face released an AI agents course today. This free course will take you on a journey, from beginner to expert, in understanding, using, and building AI agents.

GOOGLE IS SHIPPING GEMINI MODELS FASTER THAN ITS AI SAFETY REPORTS

Google has launched an AI reasoning model, Gemini 2.5 Pro. The model leads in coding and math capabilities, but Google hasn't released safety reports yet. Google plans to publish these reports after collecting feedback from experimental releases, though this approach raises transparency concerns. Despite pledges for transparency, Google seems to prioritize speed in model deployments, diverging from industry norms for responsible AI practices.

CODE WITH CLAUDE DEVELOPER CONFERENCE

Anthropic has announced its first developer event focused on hands-on sessions and best practices for building with Claude - it is set to take place in May in San Francisco.

THE LLM COURSE FROM HUGGING FACE

Hugging Face has revamped its popular NLP course into a broader LLM curriculum with expanded chapters on fine-tuning, reasoning models, and modern AI agent workflows.

DEVIN, THE VIRAL CODING AI AGENT, GETS A NEW PAY-AS-YOU-GO PLAN

Cognition launched a $20 entry-level plan for its AI programming tool, Devin, which has been improved to handle complex coding tasks better.
