Breaking — Partnership Restructure

Microsoft and OpenAI have overhauled their landmark deal, ending Azure’s exclusive cloud lock and removing the AGI-trigger clause that once gave Microsoft veto rights if OpenAI crossed into superintelligence territory.

Microsoft and OpenAI Tear Up Exclusivity — AGI Clause Gone, Deal Extended to 2032

Azure is no longer the only cloud that can run OpenAI’s products. A restructured agreement uncaps what OpenAI owes Microsoft and strips the provision that once froze the partnership if AGI arrived.

Microsoft and OpenAI announced Monday a comprehensive restructuring of the partnership that has defined the AI industry since 2019, ending Azure’s exclusive cloud hold on OpenAI products while simultaneously extending the overall agreement through 2032. Under the new terms, OpenAI can now ship its models and services across any cloud provider it chooses — Azure’s position shifts from exclusive to “preferred,” with OpenAI products continuing to launch first on Azure before appearing elsewhere.

The most closely watched change involves the revenue share OpenAI has historically owed Microsoft. The new structure introduces a cap on that figure through 2030, giving OpenAI greater financial clarity as it scales toward a projected $100 billion in annualized revenue. The exact cap was not disclosed in the public announcement, but people familiar with the negotiations described it as “substantially below what the previous uncapped structure would have required.”

Equally significant is the removal of the AGI trigger clause — a provision in the original agreement that suspended the partnership’s financial terms if OpenAI’s own board determined it had achieved artificial general intelligence. The clause, long a source of legal and practical ambiguity, had become a flashpoint during OpenAI’s board crisis in late 2023. Its deletion signals both companies prefer a commercially predictable relationship over a structure tied to contested definitions of machine cognition. Microsoft retains its equity stake and preferred-partner status through 2032.

Courtroom

Musk v. Altman Trial Opens in Oakland; OpenAI Counsel: “He Quit, Saying They Would Fail for Sure”

A nine-person jury is seated at the Ronald V. Dellums US Courthouse as the most consequential AI litigation in history formally begins. Musk seeks $130 billion in damages and Altman’s removal from OpenAI.

The trial of Musk v. Altman et al. officially began Monday before Judge Yvonne Gonzalez Rogers in the Ronald V. Dellums Federal Courthouse in Oakland, California, with jury selection completed and opening statements delivered. Nine jurors were empaneled after several days of voir dire over the preceding week. The case centers on Musk’s claim that OpenAI broke its founding charitable mission when it restructured as a for-profit entity, and that he was defrauded in the process.

OpenAI’s lead counsel delivered a blunt opening that set the adversarial tone for what could be a multi-week proceeding: “We are here because Mr. Musk didn’t get his way at OpenAI. He quit, saying they would fail for sure.” The argument is that Musk’s involvement was always contingent on controlling the organization, and that when that control was denied, he departed — before the company became the most valuable AI enterprise in history.

Musk’s legal team countered that OpenAI’s original nonprofit charter constituted a binding commitment to develop AI “for the benefit of humanity,” and that the for-profit conversion violated both that charter and Musk’s reasonable reliance on it when he donated roughly $44 million in the early years. Musk’s lawyers are seeking a court order compelling OpenAI to roll back its for-profit structure, oust Sam Altman as CEO, and pay approximately $130 billion in damages — a figure that roughly corresponds to their estimate of OpenAI’s current enterprise value.

China Blocks Meta’s Manus Deal

Beijing orders a full unwind of Meta’s $2 billion acquisition of Manus and bans two co-founders from leaving China — complicating a reversal already tangled by executives now on Meta’s payroll.

NDRC Orders Meta to Unwind Manus Acquisition; Two Co-Founders Barred From Leaving China

China’s National Development and Reform Commission issued a formal order Monday requiring Meta to fully unwind its $2 billion acquisition of Manus, the Singapore-incorporated agentic AI startup founded by Chinese engineers Xiao Hong and Ji Yichao. The NDRC cited national security concerns about the transfer of advanced agentic reasoning technology to a US entity, in a move that echoes Beijing’s 2021 block of Nvidia’s attempted Arm acquisition and signals a tightening posture on AI M&A involving Chinese-origin talent.

The order is complicated significantly by timing: key Manus executives — including members of the core engineering team — had already transitioned to Meta payroll following the deal’s close earlier this year. Unwinding their employment agreements, repatriating intellectual property, and reconstituting Manus as a going concern present a legal and logistical challenge that Meta’s lawyers are understood to be assessing urgently. The two named co-founders, Xiao Hong and Ji Yichao, have been issued exit bans pending a Chinese government investigation into the circumstances of the acquisition.

Open Weights

DeepSeek V4 Goes Fully Open

Three days after a teaser preview, the complete DeepSeek V4 weights are freely downloadable — a 1.6-trillion-parameter MoE and a 284-billion compact variant, both MIT-licensed.

Open-Source Milestone

DeepSeek V4-Pro (1.6T) and V4-Flash (284B) Land on Hugging Face Under MIT License

The largest open-weight MoE ever released, V4-Pro delivers frontier-class long-context performance. Both variants are available for self-hosting, fine-tuning, and auditing — no licensing restrictions.

DeepSeek posted the full open weights for both V4-Pro (1.6T total parameters, Mixture-of-Experts architecture) and V4-Flash (284B) to Hugging Face on Monday, three days after a preview window that allowed limited API access. The MIT license terms are unrestricted: researchers, enterprises, and developers can self-host, fine-tune, fork, and audit the weights without royalties or usage constraints — the same permissive approach DeepSeek took with V3.

The release places the most capable open-weight, long-context MoE architecture ever publicly available into OSS hands. V4-Pro’s parameter count surpasses any previously open-licensed model by a substantial margin, and its MoE design — activating only a fraction of parameters per token — makes inference tractable on well-resourced consumer or cloud hardware. The V4-Flash variant targets latency-sensitive deployment scenarios. Community benchmarking is expected to begin immediately, with comparisons against GPT-5.5 and Gemini 3 Flash already underway in the research community.

ICLR Day 4: Research Wire

MedAgentGym takes ICLR’s Outstanding Paper award; IBM Research proposes “thinking without words” via abstract tokens; the World Models Workshop draws 1,500 attendees.

ICLR Outstanding Paper

MedAgentGym Wins ICLR 2026 Outstanding Paper — 72,413 Tasks Across 129 Biomedical Categories

The ICLR program committee awarded an Outstanding Paper designation to MedAgentGym, a scalable training environment for large language model agents on biomedical reasoning tasks. The benchmark encompasses 72,413 task instances across 129 categories drawn from 12 real-world biomedical scenarios — clinical decision support, drug interaction prediction, genomic analysis, and more. Agents trained within the sandbox using offline reinforcement learning followed by online RL fine-tuning showed dramatic improvements: the Med-Copilot model variant gained +43% on held-out biomedical tasks and +45% on cross-domain generalization, relative to its baseline. Program chairs cited the scale, ecological validity, and reproducibility of the training framework as decisive factors in the award.

Reasoning Efficiency

“Thinking Without Words”: IBM Research Cuts Reasoning Tokens 11.6x With Abstract Chain-of-Thought

IBM Research presented a preprint describing Abstract Chain-of-Thought (ACoT), a method that replaces natural-language reasoning traces — the step-by-step prose that enables chain-of-thought — with discrete “abstract” tokens drawn from a reserved vocabulary. Models are trained to think in this compressed token space via a policy-iteration warm-up that first learns to translate natural-language chains into abstract sequences, then fine-tunes on the compact representations. On math, instruction-following, and multi-hop question answering benchmarks, ACoT achieves up to 11.6x fewer reasoning tokens at comparable task performance, suggesting that human-legible reasoning traces may be computationally wasteful scaffolding rather than a fundamental requirement for complex problem solving.

ICLR Workshop

ICLR World Models Workshop Draws 1,500 Researchers on Knowledge Extraction and Cross-Modal Scaling

The ICLR 2026 World Models Workshop convened Monday with more than 1,500 registered participants, making it one of the largest satellite workshops of the conference. Sessions covered three main tracks: understanding and knowledge extraction from learned world representations, large-scale training and evaluation methodology, and cross-modal control-centric scaling — the challenge of building models that reason jointly over video, language, physics simulation, and motor control. The workshop reflects the rapid institutionalization of world model research as a distinct subfield, distinct from both purely language-centric scaling and traditional model-based reinforcement learning.

Bugcrawl Spotted in Leaked UI Screenshots — 10 Parallel Agents Scour Entire Codebases for Bugs

Leaked UI screenshots circulating Monday appear to show a Claude Code feature called Bugcrawl, which deploys 10 parallel Claude agents across a full codebase simultaneously to surface bugs and propose fixes. The screenshots suggest a UI that surfaces agent findings in a unified review panel, similar in spirit to the /ultrareview command released April 22 but oriented toward defect detection rather than code quality. Bugcrawl appears targeted at Teams and Enterprise tier users; no official announcement has been made. Anthropic declined to comment on unreleased features when contacted by Testing Catalog, but did not deny the screenshots’ authenticity.

GitHub Copilot CLI

Copilot CLI v1.0.37: Location-Based Permissions Now On by Default, Plus Clipboard Fix

GitHub Copilot CLI v1.0.37 graduated location-based permission persistence from experimental to on by default — the system now remembers per-directory approval decisions across sessions, reducing repeated prompts. Additional changes include shell completion support for bash, zsh, and fish; a session picker that cycles through sort orders (most recent, alphabetical, most used); and a fix for an X11 clipboard handle leak on Linux that caused resource exhaustion in long-running sessions.

GitHub Billing Change

GitHub Copilot Moves to AI Credits on June 1 — Code Review to Consume Actions Minutes

GitHub announced Monday that on June 1, 2026, Copilot’s usage-based billing will migrate from Premium Request Units to a unified AI Credits system. Simultaneously, Copilot code review on private repositories will begin consuming GitHub Actions minutes — a change that aligns AI-powered review with the platform’s existing CI/CD cost model. Public repositories remain unaffected by both changes. GitHub said the AI Credits model simplifies cross-feature usage tracking and will eventually extend to other AI-powered GitHub features beyond Copilot.
