Grok 4.5: SpaceX & Tesla test new 1.5t-parameter AI. 6h ago · 0:00 listen · Source: The Hans India Summary. Elon Musk has announced that xAI's new Grok 4.5 model is now in private beta testing at SpaceX and Tesla. This model is built on a 1.5-trillion-parameter foundation and was trained with Cursor coding data. Musk shared that early evaluations suggest Grok 4.5's performance is close to, and possibly even better than, Anthropic's Claude Opus. He also mentioned that xAI plans to release new AI models "completely trained from scratch" every month for the rest of the year. This indicates a rapid acceleration in the company's AI development efforts. The V9 foundation model, which Grok 4.5 uses, is roughly three times larger than the current production model. This news shows that advanced AI models are being integrated into major technology companies. This is an AI-generated audio summary. Always check the original source for complete reporting.
Justice Department backs xAI's innovative tech in datacenter environmental case. June 27, 2026 The U.S. Justice Department has intervened in a legal case involving xAI, an artificial intelligence company founded by Elon Musk, urging a federal court to dismiss a lawsuit related to alleged environmental violations at its Mississippi datacenter. The lawsuit accuses xAI of installing methane-powered turbines at the site without obtaining the necessary air permits, thus breaching environmental laws. The plaintiffs argue that these turbines could emit harmful pollutants and have requested the court to halt their operations. In defense of the project, the Justice Department emphasized the datacenter's role in advancing AI technology, highlighting its significance for national and economic interests. Government attorneys contended that the energy systems at the facility are critical for sustaining large-scale AI projects, implying that the development of such infrastructure requires certain allowances. However, this stance has been met with resistance from community groups and environmental organizations. They assert that compliance with environmental regulations is mandatory for companies operating AI infrastructures, regardless of the purported importance of their projects. These groups insist that local communities should have the authority to hold corporations accountable for any pollution-related issues. The Colossus datacenters, as xAI's facilities are known, have drawn criticism from residents in nearby areas who are concerned about emissions and potential environmental damage. The situation underscores a broader tension between the rapid expansion of AI infrastructure and the imperative to safeguard public health and environmental standards.
xAI, Elon Musk's artificial intelligence company, has reportedly acquired Safe Superintelligence (SSI) in a deal valued at approximately $60 billion. SSI was co-founded in 2024 by Ilya Sutskever, a Pakistani-origin entrepreneur and former OpenAI chief scientist, alongside Daniel Gross and Daniel Levy. The startup focused on developing safe and highly capable AI systems, attracting significant investor interest despite operating with a low public profile. The acquisition is expected to strengthen xAI's position in the competitive AI landscape by combining SSI's AI safety research with xAI's technological ambitions. Industry analysts view the deal as a strategic move that could reshape the balance of power amongst major AI firms, creating one of the most influential AI research organisations globally.
Elon Musk's xAI, SpaceX face class action lawsuit. Elon Musk's companies, xAI and SpaceX, are facing a proposed class-action lawsuit filed by residents in Mississippi who allege that a massive power plant supporting nearby artificial intelligence data centers has created unbearable levels of noise, disrupted their daily lives, and reduced the value of their properties. The case marks another legal challenge tied to the rapid expansion of AI infrastructure and its impact on surrounding communities. The lawsuit was filed in federal court in Oxford, Mississippi, by three residents seeking to represent a class of more than 10,000 people living near the facility. The complaint names xAI, SpaceX, and xAI subsidiary MZX Tech as defendants, alleging that the companies negligently failed to prevent excessive noise generated by the gas-powered turbines that supply electricity to the data centers. Elon Musk himself was not named as a defendant. According to the plaintiffs, the turbines produce constant and intrusive sounds that can be heard day and night. The lawsuit describes the noise as "omnipresent and inescapable," arguing that residents have suffered emotional distress, sleep disturbances, and a loss of enjoyment of their homes. They also claim the continuous noise has negatively affected local property values and transformed peaceful neighborhoods into areas affected by industrial activity. The power facility was developed to support xAI's growing data center operations in Southaven, Mississippi. The project is part of a broader effort to build the large-scale computing infrastructure necessary to power advanced AI systems. As demand for artificial intelligence increases, technology companies are constructing increasingly powerful data centers that require enormous amounts of electricity and cooling resources. The lawsuit argues that the rapid growth of AI infrastructure has created new environmental and quality-of-life concerns for nearby communities. The plaintiffs claim the companies placed the demands of AI development ahead of the rights of local residents by operating equipment that allegedly generates excessive noise around the clock. They accuse the defendants of creating a public nuisance and acting negligently by failing to adequately control the disturbances. The residents are seeking compensation for emotional distress, reduced property values, and other alleged damages. They are also requesting the disgorgement of unspecified profits connected to the operation, arguing that the companies should not financially benefit from activities that allegedly harmed surrounding communities. xAI and SpaceX did not immediately respond to requests for comment regarding the lawsuit. The case comes amid broader legal scrutiny of the companies' AI-related facilities. Earlier in 2026, the NAACP filed a separate lawsuit accusing xAI of violating environmental laws in connection with the same Mississippi facility and its operations. The U.S. Department of Justice later indicated it may intervene in that dispute due to broader legal and policy questions involving AI infrastructure. The lawsuit highlights an emerging legal conflict between the technology industry's race to expand artificial intelligence capabilities and the rights of communities located near large-scale data centers. As AI companies build larger facilities requiring significant power generation, courts may increasingly be asked to determine how much disruption nearby residents must tolerate. Public nuisance claims have historically been used to address activities that interfere with the public's health, safety, comfort, or use of property. In this case, the plaintiffs will need to prove that the alleged noise is unreasonable and that the companies' operations directly caused the harms they describe. The outcome of the case could influence how technology companies design and operate future AI facilities. A ruling favoring residents may encourage stricter noise controls, additional environmental reviews, or greater community engagement before new AI data centers are developed. Although the lawsuit is still in its early stages and no court has determined whether xAI or SpaceX violated the law, the dispute represents a significant legal test over the environmental and community consequences of the expanding artificial intelligence industry. Key legal outcomes. * Mississippi residents filed a proposed class-action lawsuit against xAI, SpaceX, and MZX Tech. * The lawsuit alleges public nuisance and negligence caused by excessive noise from power turbines. * More than 10,000 residents may be included in the proposed class. * Plaintiffs seek damages for emotional distress, lower property values, and other alleged harms. * The case is in its early stages, and no court has ruled on the allegations. Why it matters. * The lawsuit is one of the first major legal challenges involving AI data center noise impacts. * It highlights the environmental and community costs of the AI expansion race. * The outcome could shape future regulations for large-scale AI infrastructure. * The case tests the limits of nuisance law in addressing modern technology projects. * It may influence how technology companies balance innovation with local community concerns.
