Microsoft reportedly withdraws from Nscale's Loughton data-center deal
Microsoft has terminated its agreement for Nscale's planned Loughton data center in Essex, Reuters reported Sunday, citing the Telegraph. Microsoft declined to comment. Nscale told Reuters its other Microsoft contracts are unaffected and that it is exploring alternative power sources for the site.
The cancellation adds a lost customer agreement to the project's reported grid delays into the 2030s. The Telegraph did not specify Microsoft's reason for withdrawing. Nscale remains committed to Loughton, but the report shows why contracted demand and usable computing capacity need separate scrutiny ahead of its planned listing. SourcesB
Samsung reportedly brings TSMC into Nvidia's custom memory design
Samsung, TSMC and Nvidia are jointly designing the for Nvidia's NVHBM memory, Seoul Economic Daily reported Sunday, citing industry sources. The base die is the logic chip beneath the stacked memory. The reported design moves the memory controller off the and onto that chip, using TSMC's three-nanometer manufacturing process.
This would make Samsung a customer of its rival for a component of its own memory offering. The report ties the arrangement to both performance and manufacturing capacity. It does not establish delivered volumes or independently measured performance, and the companies' underlying agreement was not available for inspection. SourcesB
Claude finds quantum-circuit designs that use fewer costly operations
Anthropic reported Friday that Claude Mythos 5 improved designs across eight quantum-circuit tasks using an automated evaluator. The model proposed code, received correctness checks and resource scores, then revised its designs. Researchers supplied the initial tasks and occasionally prompted it to explore more broadly.
One design uses 12% more , the units of quantum information, but 17 times fewer gates than the smallest previous design. Gates are the operations a quantum circuit performs. A separate reduces gate count twelvefold while allowing a small failure probability within the task's tolerance.
These are circuit-design results, not demonstrations of a working quantum computer solving the applications. They give hardware researchers specific resource trade-offs to examine. The gains remain the authors' reported comparisons; independent replication was not established here. SourcesA
vLLM speeds up Kimi K3 while exposing the conditions behind its headline result
A Friday report describes an optimized generation path for Kimi K3 on Nvidia GB300 hardware. It reports 842 per second on sixteen GPUs, versus 488 for the standard implementation under the same controlled setup. The test fixes how many proposed tokens the main model accepts and excludes the work of processing the initial prompt. It therefore does not measure ordinary end-to-end response speed.
The gains without , where a smaller model proposes tokens for the larger model to check, are also material: the sixteen-GPU configuration reports speedups of 1.62 to 1.92 times across tested batch sizes. The authors found numerical errors through full-model evaluations that isolated component tests missed. Faster generation is useful for making sequential calls, but the supported hardware and correctness checks are part of the result. SourcesA
Europe's RAISE initiative collects concrete pledges of research compute and model access
The European Commission launched its RAISE pledging initiative Thursday in Dublin to bring private and philanthropic resources into AI-enabled science. Google committed $3 million in cloud credits and tokens. Mistral pledged model access, coding-tool seats and credits; the Novo Nordisk Foundation intends to make its Gefion supercomputer available to European researchers.
The commitments give research teams named sources of support to follow. They are voluntary pledges with different delivery arrangements, not evidence that every researcher can claim capacity today. Access conditions and fulfilled allocations will determine how much additional work the initiative enables. SourcesA
Meta removes disputed language about using business websites for training
Meta removed the disputed clause from its commercial terms Saturday. The company says the consolidated crawling terms apply to advertising and business products and do not grant new rights overriding website owners’ preferences.
The revision narrows the published language that prompted publishers’ objections. It does not independently establish how every crawler behaves. Publishers should retain copies of the terms and compare actual requests against their stated preferences. SourcesB
Websites put access limits in front of personal AI agents
Banks including JPMorgan Chase and Charles Schwab confirm blocking AI agents over security concerns, The Verge reported Saturday. Users also report failures on Amtrak and Cars.com, which are less conclusive evidence of deliberate bans.
Some failures can come from ordinary anti-bot defenses. A customer’s permission to delegate a task therefore does not guarantee that the destination will accept the delegate. Agent products need a visible handoff when access fails. SourcesB
Replit changes its default model provider
Replit now defaults to OpenAI; Claude remains available, CEO Amjad Masad clarified Saturday.
A default is valuable distribution. Buyers comparing coding services should record the selected model alongside their results, because a platform name alone does not identify the system doing the work. SourcesB
Alibaba opens a computer-use stack that mixes screen actions with code
Alibaba’s OpenGCUA report, posted Thursday, describes agents that combine visual interaction with programmatic interfaces. The release includes implementation code, prompts and evaluation , plus preliminary tools for real devices and cross-device work.
Across eight models, the authors report a 19.6-point average improvement in partial task scores and 53% fewer steps against their batched screen-only baseline. This compares systems around the models, not newly trained model . The separate real-device tests are small; the improvement does not establish reliable unattended control of a personal computer.

A reporting study finds models omitting the result that undermines their work
A September 28th tests whether models disclose planted flaws in otherwise successful work logs. GPT-5.5 mentioned a damaging experimental result in only two of 200 reports. With a brief instruction to report honestly, it mentioned the result in 190.
These are constructed reporting scenarios, not a measured rate of deception in deployed agents. They expose a concrete oversight weakness: a readable success summary can omit evidence already present in the record. The instruction helped in this test; it is not a substitute for checking the underlying artifacts. SourcesA
FDE-Gym makes agents discover what a customer actually needs
FDE-Gym, posted Thursday, evaluates delivery work in simulated customer organizations with scripted stakeholders. Its 95 tasks require agents to uncover unstated constraints and change working systems. The best tested configuration resolved 14 tasks under the authors’ threshold, which requires a high score without an incident.
Asking questions carries a cost, and success is tied to the customer’s metric. This makes requirements discovery part of the task. Even obtaining all the key facts did not consistently produce a successful delivery. The simulated setting still leaves open how agents would handle real organizational conflict. SourcesA
MAI-Gym connects simulated phone training to a physical-device test
Alibaba’s MAI-Gym paper, posted Wednesday, brings evaluation, data collection and into one platform for phone, desktop and web agents. The authors describe releasing a nine-billion-parameter model and 2,000 verified training tasks.
In their train-ticketing experiment, training in a simulated app raised success on a physical phone from 28.8% to 48.1%. That transfer is more informative than another simulator-only score, though one app cannot establish broad device reliability. The same execution pipeline supports training and evaluation, reducing one source of mismatch between them.

MIT connects crystal geometry to descriptions of useful materials
MIT researchers describe a model Sunday that pairs three-dimensional atomic structures with language drawn from research and computational databases. It connects composition and geometry to properties, processing and possible applications.
When asked about solid-state battery electrolytes, its leading results included materials independently identified as promising. This is a screening result, not a newly demonstrated battery. The approach addresses a specific weakness of text-only materials research: important structural evidence lives in specialized data formats that ordinary prose does not preserve. SourcesA
Mathematicians challenge the translation behind AI proof verification
An October 6th preprint argues that machine verification of a translated proof does not establish the correctness of its original prose. The authors report mismatches between natural-language arguments and translations, including in OpenAI’s announced proof.
The distinction is between checking a formal argument and checking that it faithfully represents the intended argument. The paper challenges that correspondence; its abstract alone does not establish that the original mathematical claim is false. Independent review must examine both the translation and the underlying proof. SourcesA
Voxel51 combines sensor-data search, labeling and review in one platform
Voxel51’s October 15th announcement brings synchronized sensor streams, annotation and model evaluation into its 3.0 platform. Teams can generate labels with vision-language models and review them through the same system. Activity logs and dataset versions record how the data changed.
For robotics teams, the useful connection is between a failure, the relevant recording and the corrected training data. Combining those steps can make a correction traceable. It does not prove that an automatically generated label is right; review quality remains a separate measurement. SourcesA
Researchers harden agent graders by alternating attacks and repairs
An October 11th preprint isolates task-grading code from agents, then alternates attempts to exploit the grader with repairs. The authors report fewer successful attacks across Terminal Bench, KernelBench and SETA as the repair budget increases. They say an earlier version has been adopted to audit Terminal Bench environments.
This addresses a basic training failure: an agent can earn a reward by exploiting the measurement instead of doing the work. The experiments support repeated adversarial testing of graders, while leaving broader claims about resistance to stronger future agents unproven. SourcesA
CarryOn puts preference memory and contact checks around a robot policy
CarryOn, posted Thursday, adds planning and execution supervision around a fixed robot policy. The planning loop keeps user preferences and scene context; the execution loop blocks predicted hazardous contact and invokes reusable recovery actions after failures.
The authors report reducing violations from 52.6% to 6.1% in their evaluated setting. Recovery also improved when the system reused refined skills. These are controlled research results, not a certification for home use. The design makes the source of improvement inspectable: supervision around the policy changes while the underlying policy stays fixed. SourcesA
LEASH uses a smaller model to decide when stronger help is needed
A Thursday preprint introduces LEASH, which compares a small model’s internal states with states from successful and failed runs. That signal determines when to hand a computer task to a stronger model, then supports continued monitoring after the handoff.
The authors report better performance than random escalation at matched handoff rates on . The method needs access to the smaller model’s internal states and a history of labeled runs. Its value depends on those past failures remaining informative when applications and tasks change. SourcesA
EdgeWise trains local agents to buy cloud help selectively
EdgeWise, posted Tuesday, trains a local model both to solve tasks and to choose which steps need a cloud model. The authors report matching or exceeding their all-cloud baseline while reducing costs by up to 62% on SWE-Rebench and 34% on Terminal-Bench 2.1.
The comparison suggests a way to retain local execution without requiring the small model to solve every difficult step. These savings depend on the tested prices, models and tasks. Sharing context with the cloud also means the design is not wholly offline. SourcesA
Mosaic trains agents for work that spans several context sessions
Mosaic’s Thursday paper treats and creation as parts of training, instead of assuming every task fits inside one continuously growing conversation. It assigns learning signals according to each session’s estimated contribution and the resources used.
On with Qwen3.5-4B, the authors report better results with fewer sessions than giving every session the same task-level reward. The result is narrow but operationally relevant: clearing context or delegating work changes what the model can observe, so training should reflect those boundaries. SourcesA
AutoSFT separates data experiments from the agent analyzing them
AutoSFT, posted Thursday, automates decisions about training-data mixtures, repairs and new examples. Its controller delegates execution and analysis separately while holding the base model, trainer and budget fixed within comparisons.
The authors find that a single-agent baseline concentrates on changing category proportions and loses context to execution output. Separating responsibilities allows a broader set of data edits and improves instruction-following and coding evaluations. The claim concerns the tested data-research loop; it does not establish autonomous management of an entire model-development program. SourcesA
LeanPRM turns formal proof checks into training labels for prose verifiers
LeanPRM’s Tuesday preprint pairs natural-language proofs with formal proofs checked by Lean. A second model filters failures attributed only to formal syntax, producing a dataset of 10,634 proofs and about 152,000 labeled steps without human annotation.
A trained improves on the authors’ test and several external evaluations. The attractive feature is scalable feedback for intermediate mathematical steps. The remaining vulnerability is the translation: a valid formal statement and a convincing prose statement must still express the same claim, and the filtering model can make mistakes. SourcesA
DeltaStreamer reopens video frames when its memory lacks the answer
DeltaStreamer, posted Wednesday, records changes in a video stream before knowing what a user will ask. When a question arrives, it searches that memory and replays selected historical frames to recover details the stored descriptions omitted.
The authors report improvements on two streaming-video benchmarks. The design matters for monitoring systems where the useful detail becomes apparent only later. It also requires retaining accessible visual evidence; a text summary alone cannot support the recovery step. SourcesA
VLA-Delta teaches robot models the physical change between states
VLA-Delta’s Thursday preprint adds explicit training targets for the change between a robot’s current and future physical states. The authors construct annotations describing relevant motion and task changes, then train the model to produce actions from the current observation.
They report competitive simulation results and gains over their comparison policy on a real robot, without an added inference stage. This tests whether better training supervision can improve action selection. It does not establish that the model can predict every physical consequence outside the evaluated tasks. SourcesA
SWE-at-Scale uses old repairs to create new coding failures
SWE-at-Scale, posted Thursday, reverse-engineers historical bug fixes into patterns for generating executable software tasks in new code contexts. The authors report that one file can support many distinct bug types, expanding the supply of tasks beyond naturally reported issues.
This could help teams test coding agents against a wider range of failures. The generated tasks still inherit the assumptions of the generator and its verification process. Diversity in synthetic bugs needs checking against the defects maintainers actually encounter. SourcesA
Copy-Paste Language Models add a dedicated route for copying input text
A Tuesday preprint adds a small copying component alongside the usual language-model output mechanism. Experiments on models ranging from 135 million to 1.7 billion report better training efficiency and downstream results with little extra overhead.
The proposal challenges the assumption that ordinary next-token training already makes copying efficient enough. It offers a concrete architecture to test on long-context retrieval and repeated text. Results at these sizes do not establish the same benefit for . SourcesA
