Multimodal Embedding & Reranker Models with Sentence Transformers

[AINews] Meta Superintelligence Labs announces Muse Spark, first frontier model on their completely new stack

a quiet day lets us reflect on MSL finally shipping!

GenLCA: 3D Diffusion for Full-Body Avatars from In-the-Wild Videos

We present GenLCA, a diffusion-based generative model for generating and editing photorealistic full-body avatars from text and image inputs. The generated avatars are faithful to the inputs, while supporting high-fidelity facial and full-body animations. The core idea is a novel paradigm that...

VersaVogue: Visual Expert Orchestration and Preference Alignment for Unified Fashion Synthesis

Diffusion models have driven remarkable advancements in fashion image generation, yet prior works usually treat garment generation and virtual dressing as separate problems, limiting their flexibility in real-world fashion workflows. Moreover, fashion image synthesis under multi-source...

ALTK‑Evolve: On‑the‑Job Learning for AI Agents

Selective Neuron Amplification for Training-Free Task Enhancement

Large language models often fail on tasks they seem to already understand. In our experiments, this appears to be less about missing knowledge and more about certain internal circuits not being strongly activated during inference. We explore Selective Neuron Amplification, which increases the...

ConceptTracer: Interactive Analysis of Concept Saliency and Selectivity in Neural Representations

Neural networks deliver impressive predictive performance across a variety of tasks, but they are often opaque in their decision-making processes. Despite a growing interest in mechanistic interpretability, tools for systematically exploring the representations learned by neural networks in...

Stress Estimation in Elderly Oncology Patients Using Visual Wearable Representations and Multi-Instance Learning

Psychological stress is clinically relevant in cardio-oncology, yet it is typically assessed only through patient-reported outcome measures (PROMs) and is rarely integrated into continuous cardiotoxicity surveillance. We estimate perceived stress in an elderly, multicenter breast cancer cohort...

[AINews] Anthropic @ $30B ARR, Project GlassWing and Claude Mythos Preview — first model too dangerous to release since GPT-2

Anthropic steps up the offensive vs OpenAI's upcoming IPO woes

Safetensors is Joining the PyTorch Foundation

Extreme Harness Engineering for Token Billionaires: 1M LOC, 1B toks/day, 0% human code, 0% human review — Ryan Lopopolo, OpenAI Frontier & Symphony

We shed light on OpenAI's first Dark Factory for the first time.

[AINews] Gemma 4 crosses 2 million downloads

a quiet day lets us give due respect to the enormously successful Gemma 4 launch

[AINews] Good Friday

a quiet day.

Gemma 4 and what makes an open model succeed

Hint: it's not benchmark scores.
