AIDelphi, which turns experts' knowledge into digital minds, runs its Python backend on Vercel with a 10-person team and no dedicated infrastructure role. The stack uses Vercel Workflows for long-running agents and Vercel Queues for background jobs. The team reports more than 100 production deploys a day.

AIPeriodic Labs, the team behind high-throughput materials labs in Menlo Park, reports progress on one of condensed matter physics' hardest problems. Its open-source model Neon, trained with mid-training and RL on 1,300 H200s plus months of lab data, surpasses GPT-6 Astra on the company's analysis benchmark. The work targets materials science challenges including superconductors, magnets, and semiconductors.

AIGreg Brockman says OpenAI's Astra and Luna are taking off. A quoted post reports that Astra led last week's spending while Luna led by a wide margin in token usage, compared with Anthropic.

AICognition and AWS have entered a multi-year Strategic Collaboration Agreement to help enterprises deploy the Devin autonomous engineer in production. Devin can be purchased through AWS Marketplace, and the companies are exploring deeper engineering integrations within customers' AWS environments. Mercedes-Benz reportedly used Devin to analyze more than 200,000 lines of COBOL, reducing an estimated eight-month modernization project to eight days.

Why it matters: The collaboration shows how an autonomous coding agent is being packaged for enterprise legacy modernization inside existing AWS environments, with concrete customer migration figures.

AIPeriodic Labs chose SGLang and Miles to build Neon, an open-source model it says surpasses GPT-6 Astra on its analysis benchmark after mid-training and RL on 1,300 H200s. RadixArk says Periodic extended both frameworks for scientific RL at trillion-parameter scale, delivering more efficient training, lower memory use, and 2.5x faster inference. The work has been contributed back to both projects.

AILangChain is using Baseten Loops, a managed fine-tuning service, to train custom models for LangSmith Engine, its in-platform agent that debugs and improves AI agents. The article says LangChain fine-tunes large open-weight models on agent traces and trains smaller open-weight models such as Qwen for tasks like failure-mode categorization. Baseten Loops supports supervised fine-tuning, reinforcement learning, and long-context workloads, and lets checkpoints be evaluated and deployed directly to inference.

AIAir Street Capital has led a $40 million Series A round in Jack & Jill, with Madrona joining and existing investors Creandum and Entrepreneurs First investing again.

AIWaymo, Nihon Kotsu and GO have agreed to prepare a commercial, fully autonomous ride-hailing service in Tokyo, targeting first public rides in 2027. The service will be available through the GO and Waymo apps, starting with an initial fleet and expanding to around 100 vehicles across key Tokyo neighborhoods. The launch depends on regulatory approval from national and local authorities and completion of ongoing validation.

AISatya Nadella says Quincy, Washington shows what datacenters can achieve when built alongside local communities and expanded over time. The post is a brief remark, with no figures or specific commitments stated in the text provided.

AIOracle co-CEO Mike Sicilia argued on the Q1 FY 2027 earnings call that AI accelerates rather than replaces packaged applications, and promised an "agentic AI accelerator" in October to compress SaaS deployments from years to months. Oracle's SaaS revenue grew 10 percent, while software license revenue fell 3 percent to $5.5 billion and cloud revenue rose 60 percent to $11.6 billion. The company also said GPUs coming up for renewal were renewed or resold at a 20 percent premium and that it turned on 850 MW of new datacenter capacity in the quarter.

AILaravel announced last week that it no longer accepts GitHub issues and requires contributors to submit pull requests instead. The article argues that PR-only policies filter out spam issues and help maintainers, since users can now generate PRs with AI.

AIThe CEO of AI assistant Instinct told investors he is looking to raise $1 billion in new funding. That could imply a $10 billion valuation, four times its valuation from last month.

AIOpenAI announced that a swarm of 10,000 agents produced a solution to the Navier-Stokes Millennium Problem, a result that angered mathematicians. NYU mathematician Tristan Buckmaster and Anthropic-employed collaborator Levent Alpöge had been working on related problems and released three draft papers of about 245 pages. Buckmaster said OpenAI's offer to merge efforts required acknowledging an OpenAI model and excluded Alpöge as co-author.

Why it matters: The piece separates the mathematical result from the collaboration dispute, showing how AI labs' compute spending is straining academic norms around credit and openness.

AINVIDIA's Bryan Catanzaro welcomed the idea of models that understand how humans interact and thanked builders using Nemotron Ultra. Humansand introduced Persimmon, which it describes as the first large-scale model designed to realistically simulate how people talk and interact.

AICognition has welcomed Jonathan Kelley and the Dioxus team, whose framework Cognition used extensively to build and improve Devin's performance.

The company is sharing the architecture and a playbook for building a continuous Defense Factory, where AI agents find vulnerabilities, validate them, and verify that fixes work.

Why it matters: The post shows an internal security effort using AI models to find and fix vulnerabilities, with a shared playbook for building a similar continuous defense loop.

AIMETR has reached an agreement with Anthropic to conduct an independent investigation of agent incidents at the company and the alignment properties of its models. METR says it will publish one or more reports sharing its findings and describing the terms of engagement.

AIMETR says its planned investigation will cover all questions raised in its recently updated post on how independent researchers could study AI propensities after misalignment incidents. The post defines misalignment incidents as cases where an AI agent autonomously took sophisticated, sustained actions violating human intent.

AIJakub Pachocki said he is grateful that Paul Christiano is joining the OpenAI Foundation board and noted there is much work ahead. The post itself gives no further details about Christiano's role or the Foundation's plans.

AIMicrosoft and the American Federation of Teachers announced a first-of-its-kind agreement setting a national AI safety and privacy standard for schools. The standard states that students are not products, teachers are not beta testers, and schools are not sources for data collection or experiments. Microsoft says it will make these protections available to every school district in the US.

AICognition's Devin agent, directed by Eric Lu, factored the 260-digit RSA-260 number using a new GPU implementation of the general number field sieve built on CADO-NFS. The author estimates the run cost about 13.5 GPU-years, roughly $400k at market prices, and projects RSA-1024 factoring at around $30M, while RSA-2048 is not meaningfully affected.

Why it matters: The source gives a full cost breakdown and scaling estimates for RSA factoring on GPUs, showing how far the cost of breaking RSA-1024 has fallen.
