ATLAS: A WORLD MODEL FOR SPATIAL INTELLIGENCE

Atlas is a world generation model pretrained from scratch to natively operate on text, images, video, and 3D. It combines all inputs into a shared spatial context and uses that context to generate what comes next. The model is built to scale, and its performance improves with increased training compute. Atlas can perform a broad range of tasks spanning world generation, reconstruction, and simulation. Video examples of what the model is capable of are available in the article.

AI STARTUP COGNITION SET TO RAISE AROUND $1 BILLION AT A $47 BILLION VALUE

Cognition is set to close a new round of funding of around $1 billion. The final raise size may exceed that amount as Cognition is fielding outsized demand for the round. The startup is now bringing in more than $900 million in annualized revenue. The new funding round would vault its valuation to about $47 billion.

THE EFFICIENT FRONTIER OF LLM INFERENCE

Frontier models offer the highest degree of intelligence at a given cost or size. Efficient frontiers also exist in inference engineering. This is most often expressed as a trade-off between latency and throughput, but researchers can also exchange quality for throughput, or intelligence for speed. This article details what inference engineering techniques let researchers target a point on the frontier and which techniques push the frontier out.

FLUID COMPUTE

Vercel described Fluid, a unified compute layer that dynamically configures infrastructure for different workloads and absorbs burst capacity. The system already powered builds, sandboxes, and functions at volumes exceeding a trillion requests per month.

WHAT COMES AFTER HBM

A handful of early-stage memory technologies could yield either faster access speeds than current HBM or HBM-bandwidth with NAND-like density. Technologies like magnonics and vertical FeRAM stand out as being possible platonic ideals for memory, but they have a very long way to go before being remotely commercially relevant. Commercializing these technologies will require founding teams capable of raising hundreds of millions of dollars, possibly billions. If any of these technologies make it, they would be truly revolutionary transformations of the constraints for AI and how developers think about these systems.

HUGGING FACE ATTACK POSTMORTEM: CIVILIZATIONS, REACTIONS, AND NEXT ACTIONS

It is highly fortunate that OpenAI agents attacked Hugging Face, as it is the only reason we know about all of the severe internal failures at OpenAI. Factions that are trying to dismiss what happened as nothing but engineering failures are missing what's happening. The situation is a warning shot, and we might not get another before things get quite bad.

TRAINING FRONTIER KNOWLEDGE WORK AGENTS: A 397B RL TRAINING GUIDE WITH SKYRL

Mercor and SkyRL post-trained Qwen3.5-397B-A17B on 1,928 expert knowledge-work tasks, lifting APEX-Agents Pass@1 by 70%. The recipe shows that robust environments, exact token accounting, async RL, and harness design matter as much as algorithm choice at frontier scale.
