Quest-35B open source, Emyx slashes enzyme cost

Models & Releases

QUEST‑35B: Open‑source Deep Research Agent Trained on 32 H100s

Ohio State’s NLP group released QUEST‑35B, a 35‑billion‑parameter deep‑research agent trained on 32 H100 GPUs with ~8K synthetic tasks. They open‑sourced the model weights, training scripts, data pipeline and benchmarks, letting anyone reproduce frontier research‑agent performance. This lowers the barrier to building citation‑grounded, fact‑seeking agents.

Emyx slashes training cost while beating RFdiffusion in all-atom enzyme design

Emyx is a 140 M‑parameter conditional flow‑matching model that generates all‑atom proteins for enzyme design. It matches sparse geometric constraints, runs in just 682 GPU‑hours, four times less than RFdiffusion3, yet outperforms both Proteína‑Complexa and RFdiffusion3 on the AME benchmark for fold recovery, catalytic geometry, and structural diversity.

AI model adds 18 new rare‑disease diagnoses to stalled child cases

OpenAI’s o3 Deep Research model re‑examined 376 unsolved pediatric rare‑disease cases and helped clinicians confirm 18 new genetic diagnoses, boosting yield by 4.8%. The AI supplied evidence‑linked hypotheses, letting experts focus testing on the most promising leads and showing how periodic AI‑assisted reanalysis can unlock hidden answers.

Transformer FFNs Vary Widely in Linearity, Learning Determines It, Not Architecture

The authors measure each feed‑forward block’s linear recoverability (R²_lin) via a closed‑form least‑squares fit and find a stark, non‑monotonic spread, from near‑linear (>0.99) to highly nonlinear (<0.3), across blocks in GPT‑2, Pythia‑160M and LLaMA‑160M. This variability isn’t set by the activation function; it’s a property learned during training, opening new avenues for targeted compression and analysis.

Google’s AMIE matches PCPs in disease‑management reasoning, study shows

A Nature paper demonstrates that Google’s Articulate Medical Intelligence Explorer (AMIE), built on Gemini’s long‑context models, performed on par with 21 primary‑care physicians in a blinded multi‑visit OSCE study, and beat them on treatment precision and guideline alignment. The results suggest conversational AI could soon support clinicians in chronic disease management.

Thermodynamic Diagnostics Boost LLM Hallucination Detection by 6.5 AUROC Points

The paper introduces Free‑Energy Signatures (Fes), a thermodynamic descriptor that treats each layer’s attention Laplacian as a Hamiltonian and extracts partition functions, entropy, heat capacity, and random‑matrix spectral form factors. Across six open‑weight LLMs and benchmarks, a lightweight probe using Fes outperforms previous attention‑spectral detectors, raising average AUROC by 6.5 points and achieving 0.71 in a fully unsupervised setting.

DeepMind unveils tiered AI control roadmap to curb rogue agents

Google DeepMind released version 0.1 of its GDM AI Control Roadmap, outlining a four‑pillar strategy, misuse prevention, human oversight, robust deployment, and control science. The report maps threat models to concrete defenses, from low‑cost chain‑of‑thought monitoring to future real‑time access controls, linking mitigation tiers to model capability.
