NVIDIA'S PUSH ON PHYSICAL AI

NVIDIA unveiled innovations in neural rendering, 3D generation, simulation, and reasoning models for physical AI at SIGGRAPH 2025. Highlights included new Omniverse NuRec libraries for large-scale reconstruction, Cosmos Reason VLM for physics-aware reasoning, and updates to the Metropolis vision AI platform.

ANTHROPIC'S CLAUDE CHATBOT CAN NOW REMEMBER YOUR PAST CONVERSATIONS

Anthropic released a memory function for its Claude chatbot that allows users to recall past conversations on demand. The feature supports web, desktop, and mobile, and is currently available to Max, Team, and Enterprise subscribers. Unlike OpenAI's ChatGPT, Claude doesn't build a user profile and retrieves past chats only when requested.

GPT-5S ARE ALIVE: BASIC FACTS, BENCHMARKS, AND THE MODEL CARD

OpenAI released several good models at once: GPT-5, GPT-5-Thinking, GPT-5-With-The-Router, GPT-5-Pro, and GPT-5-API. These models cut down on errors and hallucinations and are easier to use. This post provides an introduction to these models, including basic facts, benchmarks, and the model card. GPT-5-Thinking and GPT-5-Pro look like substantial upgrades to o3 and o3-Pro.

HOW MUCH POWER WILL FRONTIER AI TRAINING DEMAND IN 2030?

Epoch AI estimates the largest AI training runs will require 4-16 gigawatts by 2030, enough to power millions of homes, if current trends hold. US AI data center capacity would need to increase 10x over the next 5 years to 50 gigawatts to support this scale, roughly 5% of the nation's total power generation.

AN ESSENTIAL PRIMER FOR BUILDING ENTERPRISE-READY MCP SERVERS

MCP doesn't require compromising security - it enables security to be applied intelligently so that teams can embrace AI safely, confidentially, and without unnecessary barriers. Overly restrictive access slows innovation, frustrates developers, and prevents teams from realizing the full potential of MCP-based integrations. Organizations should already have guardrails proven to protect critical systems - they should have faith in those foundations.

FORWARD DEPLOYED AI RESEARCH

Forward Deployed Research is the discipline of living with a problem, building just enough to learn, throwing it into the wild, and pulling the feedback directly into the next version. It is where the real progress in AI is happening now: the people pushing the boundaries refuse to accept the traditional divide between research and deployment. AI may cause the distinction between scientist and engineer to blur.

PHYSICALLY CONTROLLABLE RELIGHTING OF PHOTOGRAPHS

This study presents a self-supervised approach to in-the-wild image relighting that enables fully controllable, physically based illumination editing. The approach combines the physical accuracy of traditional rendering with the photorealistic appearance made possible by neural rendering. It represents a significant step in bringing the explicit physical control over lights available in typical 3D computer graphics tools to in-the-wild relighting. A 5-minute-long video explaining the study with examples is available.

HOW BENCHMAXXED IS GPT-OSS-120B?

An analysis of currently available cutting-edge open source models found that gpt-oss-120b scored the worst on LiveBench, a private benchmark that uses secret questions. While the model looked good on release day, a bunch of critical reports have since been released. This isn't conclusive evidence that OpenAI is gaming benchmarks, but it brings up the question of whether it is worth creating meta-benchmarks that try to measure overfitting in more robust ways.

HERE IS HOW OPENAI WILL PRIORITIZE COMPUTE OVER THE NEXT COUPLE OF MONTHS

OpenAI will first make sure that current paying ChatGPT users get more total usage than they did before GPT-5, then it will prioritize API demand up to the allocated capacity and commitments it has made to customers, increase the quality of the free tier of ChatGPT, and prioritize new API demand.
