Cursor is preparing to launch a model router, a tool that automatically selects the optimal AI model for specific tasks while balancing performance and cost. The release is expected as soon as Wednesday, according to a draft company announcement reviewed by The Information. The move reflects growing industry interest in routers as a way to optimize AI deployment efficiency.

Beijing-based Moonshot released Kimi K3, a 2.8 trillion parameter open-source AI model that topped Arena's coding leaderboard ahead of OpenAI's GPT-5.6 and Anthropic's Claude Fable 5. The release has reignited debate about whether Chinese AI developers are closing the capability gap with U.S. firms, with Arena's CEO noting this marks the first time a Chinese model challenges the perception that such advances rely primarily on distilling American models.

Humanoid, a London-based robotics company, has achieved unicorn status after raising $150 million in the first tranche of a Series A funding round that values the company at $1.2 billion excluding new funds. The funding closed earlier this week, with the company reportedly aiming to raise additional capital. The milestone marks a significant validation for the UK robotics sector.

The robotics industry is splitting into two competing camps over which AI approach will power the next generation of physical robots. Vision-language-action models (VLAs), derived from large language models, compete against world models, which predict physical outcomes based on video training. Recent moves by Luma and 1X to launch world model labs signal growing momentum for the latter approach, even as major figures like Elon Musk and Jensen Huang predict a robotics ChatGPT moment is near.

Anthropic announced that Claude now writes 80% of its code, highlighting progress toward recursive self-improvement, where AI systems create the next generation without human involvement. The company simultaneously warned that this capability poses control risks, as unintended model behaviors could compound across generations and become harder to understand. The announcement reflects broader industry momentum, with OpenAI, Google DeepMind, and well-funded startups like Recursive Superintelligence and Inherent all pursuing similar capabilities.

Cognition is repositioning its Devin Desktop application as a neutral platform for managing AI coding agents from multiple providers, including competitors OpenAI and Anthropic. The move, announced Tuesday, reflects a strategic shift to compete not just with rival startups but with the AI giants that supply the underlying models. By positioning itself as a Switzerland-like intermediary rather than a locked-in vendor, Cognition aims to strengthen its market position in an increasingly crowded field of AI coding tools.

Cursor is developing software codenamed Origin to replace core GitHub functions, including repository hosting, security reviews, and automated testing features. The project, led by engineers from Graphite (which Cursor acquired), is set to launch this summer. GitHub leadership has grown concerned about competitive threats from Cursor and Anthropic as the platform faces recent outages and operational issues.

SpaceX and Cursor plan to complete their acquisition 30 days after SpaceX's public market debut, expected in mid-June. The deal will close roughly in July, following what is anticipated to be the largest IPO in U.S. history. The timing ties the AI coding tool's acquisition to SpaceX's transition to public company status, linking two of Elon Musk's ventures in a significant consolidation move.

Andrej Karpathy, a founding member of OpenAI and former director of AI at Tesla, has joined Anthropic as an employee. Karpathy announced the move on X, stating that he believes the next few years at the frontier of large language models will be especially formative. The hire represents a significant acquisition of talent for Anthropic, given Karpathy's prominent track record in AI research and development.

During cross-examination in his lawsuit against OpenAI, Elon Musk acknowledged that it is 'partly' true that xAI has distilled OpenAI's models in developing its own AI systems. The admission came on the second day of testimony in the ongoing legal dispute. The comment raises questions about the technical foundations and training methodologies behind xAI's model development efforts.

Standard Intelligence, a two-year-old startup, has raised $75 million at a $500 million valuation to develop computer use models that can autonomously operate computers and perform tasks ranging from website testing to email management and vehicle control. The startup's approach differs from traditional training methods by rethinking the data pipeline rather than relying solely on textual data. The funding round, led by Sequoia Capital and Spark Capital, represents a 16x increase from the company's seed valuation in late 2024, signaling strong investor confidence in the computer use model category.

Anthropic is investigating unauthorized access to several unreleased AI models, including Mythos, a model the company has deliberately withheld from release due to its potential for enabling cyberattacks. According to an Anthropic spokesperson, a group of unauthorized users gained access to these models. Bloomberg first reported the incident on Tuesday. The investigation is ongoing and details remain limited.
