Arcee's U.S.-made, open source Trinity Large and 10T-checkpoint offer rare look at raw model intelligence. Arcee has released Trinity Large, a 400-billion parameter open language model, alongside a raw checkpoint for researchers. This development enhances the accessibility of advanced AI tools for developers and enterprises.

By open-sourcing a 400B-parameter MoE plus a 10-trn-token raw checkpoint, Arcee sets a new U.S. benchmark for transparency. Meta’s largest open weights stop at 70B. Regulated industries can now audit and self-align, shifting compliance power from model vendors to users.

Microsoft Unveils Maia 200, An FP4 and FP8 Optimized AI Inference Accelerator for Azure Datacenters. Microsoft has unveiled the Maia 200, an AI inference accelerator optimized for Azure datacenters. This development aims to enhance performance for large language models and other AI workloads, reflecting a significant investment in AI infrastructure.

Power, not silicon, is the choke. A 200 MW Maia inference zone drains electricity for 150 k homes, nibbling at the 5 GW U.S. spare grid headroom through 2026. Microsoft trades Nvidia fees for TSMC dependence and a scramble for scarce electrons, edging out smaller users.

Why people can have Alzheimer's-related brain damage but no symptoms. Research reveals that some individuals with Alzheimer's-related brain changes do not exhibit symptoms, offering insights into resilience mechanisms against cognitive decline.

Brains can stay sharp even when packed with Alzheimer’s plaques. Among 190 donated brains, 88 showed heavy amyloid/tau but preserved cognition and unique neuron-microglia patterns, suggesting innate “cognitive armor.” Decoding these traits could seed preventive drugs within 5–10 years.

Microsoft to disable NTLM by default in future Windows releases. Microsoft's decision to disable the NTLM authentication protocol by default addresses longstanding security vulnerabilities, marking a significant shift in their cybersecurity strategy.

Ending NTLM sets a forced migration clock for millions of legacy hospital, factory and ATM systems still running the 1993 protocol. Attackers now have a final 90-120 day window, mirroring SolarWinds lag, to mass-harvest hashes before orgs can replatform.

Canucks defeat Anaheim 2-0. Vancouver defeat the Anaheim Ducks 2-0 at Rogers Arena.

Drew O’Connor’s 5-on-5 strike and Teddy Blueger’s shorthanded marker delivered a rare clean sheet and a 2-0 win, meaning seven of the club’s last nine goals have come from the bottom six—vital cover while the Pettersson unit has managed just two in its past four games. At 18-31-5 (-53 GD) and still marooned in 8th place, Vancouver now faces 24-21-9 Toronto knowing that sustained depth production, not star power, is the only credible path to making the standings gap look respectable over the final 28 games.
