Anthropic has leased a site in western Queensland for its first Australian datacentre, a $31.9bn facility that would be Australia's largest. Queensland Premier David Crisafulli called it a major win for jobs and the energy grid.

The paper shows that architectural interventions—not just data and parameter count—can change pre-training scaling exponents, leading to exponential compute savings. Looped transformers with model growth (including shared-weight variants) yield the largest exponent shifts; a 7.4B model-growth architecture matches GPT-3 13B on CORE with ~20× less compute.

Introduces FairInference, a serving system that provides delta-token latency fairness for multi-tenant LLM inference, guaranteeing that a well-behaved client's token latency degrades by at most delta compared to isolated execution. It addresses a real gap left by throughput-fair scheduling approaches that fail to protect tail latencies.

The authors analyze how reward hacking is represented internally in frontier open-source LLMs and find that simple difference-of-means vectors coherently capture reward hacking in Kimi K3, GLM 5.2, and Qwen 3.8 Max across behaviors in common evaluations. These vectors are both generalizable and interpretable, enabling reliable detection of hacking in benchmarks like DeepSWE and SWE-bench.

ImpossibleRubrics benchmarks 169 impossible tasks across six categories paired with verifiable oracle certificates, designed to stress-test rubric-based reward signals used in reinforcement learning, LLM-as-a-judge evaluation, and automated grading. It isolates whether rubrics reward honest acknowledgment of impossibility over adversarial answers.

Adoption signal: 3,231 stars today indicate breakout developer momentum. Why it matters: Its security automation can make testing and control mapping more repeatable across AI workflows, provided teams validate coverage and benchmark quality.

Adoption signal: 927 stars today indicate strong developer attention. Why it matters: It packages reusable agent capabilities instead of another model layer, signaling a shift toward portable, governed workflow components.

Adoption signal: 1,546 stars today indicate breakout developer momentum. Why it matters: It can lower the friction of deploying or operating models, so its value depends on measured gains in latency, cost, and hardware efficiency.

Adoption signal: 1,179 stars today indicate breakout developer momentum. Why it matters: It is attracting attention for tinycast — a tiny, fully native macOS launcher, hotkeys, and clipboard history; teams should verify that this capability removes a concrete workflow bottleneck before adoption.

Adoption signal: 778 stars today indicate strong developer attention. Why it matters: It is attracting attention for ever® Gauzy™ - Open Business Management Platform (ERP/CRM/HRM/ATS/PM) - https://gauzy.co; teams should verify that this capability removes a concrete workflow bottleneck before adoption.
