xAI, the artificial intelligence company founded by Elon Musk, has officially launched its latest flagship models, Grok 4 and Grok 4 Heavy. Alongside the release, the company introduced its most premium subscription tier to date, SuperGrok Heavy, which is priced at $300 per month and targeted at power users and developers.

Grok 4 is designed to compete with top-tier AI models like OpenAI’s ChatGPT and Google’s Gemini. As per xAI, Grok 4 demonstrates frontier-level performance across several benchmark evaluations. 

On Humanity’s Last Exam, an extensive test designed to evaluate general knowledge, Grok 4 scored 25.4% without using external tools, outperforming OpenAI’s o3 (high), which scored 21%, and Gemini 2.5 Pro, which scored 21.6%. 

When equipped with tools, Grok 4 Heavy scored 44.4%, making it the top-performing model in that category. For context, Gemini 2.5 Pro with tools scored 26.9%, as noted in a TechCrunch report.

xAI also highlighted Grok 4 Heavy’s “multi-agent” system, which enables multiple instances of the model to solve a problem in parallel and compare answers, similar to a study group. This collaborative approach is intended to improve both reasoning and accuracy in complex tasks.

The company also shared results from the ARC-AGI-2 benchmark, where Grok (Thinking) achieved new state of the art (SOTA) score on the test with 15.9%. As per Arc Prize in a post on X, this score is “nearly double(s) the previous commercial SOTA and tops the current Kaggle competition SOTA.”

The $300/month SuperGrok Heavy plan grants users early access to Grok 4 Heavy, as well as upcoming product features. Upcoming capabilities that are planned for release in the coming months include an AI coding model in August, a multi-modal agent in September, and a video generation system in October.

Grok 4 and Grok 4 Heavy are available via API as part of xAI’s push to engage developers and enterprise users. The company’s enterprise platform, which launched just two months ago, will also expand via partnerships with cloud hyperscalers to bring Grok models to broader infrastructure environments.

SpaceX is preparing to launch its final Starship V2 rocket on October 13, 2025. The launch closes the curtain on Starship V2 and marks the start of the ambitious spacecraft’s V3 era. 

Liftoff for Flight 11 is scheduled for 7:15 p.m. ET from Starbase in South Texas, with a 75-minute launch window. The mission will test reentry dynamics, new landing burn configurations, and heat-shield upgrades ahead of the transition to the next-generation Starship V3.

Starship V3 and beyond

Elon Musk confirmed on X that Starship V3 is already in production and could be “built & tested” and perhaps even flown before the end of 2025. The new version is expected to feature major performance and scale improvements, with Musk stating that Starship V3, provided that things go well, might be capable of reaching Mars, though V4 is more likely to perform a full-scale mission to the red planet. 

“Only one more V2 left to launch,” Musk wrote back in August following Starship’s successful Flight 10 mission. In another post, Musk stated that “Starship V3 is a massive upgrade from the current V2 and should be through production and testing by end of year, with heavy flight activity next year.”

Starship V2’s final mission

Flight 11 is designed to push the limits of Starship V2. SpaceX engineers have intentionally removed heat-shield tiles in vulnerable areas to analyze how the vehicle handles atmospheric reentry under stress, as noted in a Space.com report. The test will also refine subsonic guidance algorithms and new landing burn sequences for the Super Heavy booster that would be used for Starship V3.

“Super Heavy will ignite 13 engines at the start of the landing burn and then transition to a new configuration with five engines running for the divert phase. Previously done with three engines, the planned baseline for V3 Super Heavy will use five engines during the section of the burn responsible for fine-tuning the booster’s path, adding additional redundancy for spontaneous engine shutdowns. 

“The booster will then transition to its three center engines for the end of the landing burn, entering a full hover while still above the ocean surface, followed by shutdown and dropping into the Gulf of America,” SpaceX wrote in a post on its official website.

Elon Musk’s artificial intelligence startup, xAI, has officially broken ground on its $80 million wastewater treatment facility in Memphis, Tennessee. The project aims to reduce strain on the Memphis aquifer by 9% and repurpose 20% of wastewater from the nearby Memphis T.E. Maxson wastewater facility that would otherwise flow back into the Mississippi River.

A major step towards sustainability

City officials, including Councilman J. Ford Canale and Memphis Chamber of Commerce CEO and President Ted Townsend, joined xAI staff at the October 10 ceremony. The project was described as a long-needed solution for the region as it will have a treatment capacity of 13 million gallons daily, which would then be used for industrial cooling use xAI and the Tennessee Valley Authority (TVA). 

This means that the facility will help conserve 5 billion gallons of potable water annually, easing demand on Memphis’ primary water system. At these levels, xAI Memphis noted that its wastewater treatment facility will feature the largest ceramic membrane MBR in the world, using 13,000 membrane modules that collectively span over 900,000 square feet, roughly the size of 16 football fields. 

Construction permits have been secured for the pump station, while the main operations permit from the Tennessee Department of Environment and Conservation remains under review.

A privately funded push

The wastewater treatment facility represents a rare privately funded water reclamation initiative, with xAI covering construction costs, as noted in a Yahoo News report. The company filed preliminary plans through its affiliate CTC Property LLC in 2024, hinting at the startup’s long-term commitment to sustainable infrastructure around its growing Memphis operations. TVA CEO and President Don Moul shared his excitement for the project.

“This is a big day for Memphis, Tennessee. This initiative not only reduces our need to purchase water from MLGW for our nearby Allen Combined Cycle Plant, but it also eases demand on the region’s potable water system. By recycling water for cooling purposes, we’re helping to preserve drinking water for the community and advancing a solution that benefits both the environment and the Greater Memphis area,” he said.

Elon Musk may rethink his charity pledge after Peter Thiel’s Bill Gates warning: report

Musk reportedly took Thiel’s suggestion seriously.

Reports have emerged suggesting that Elon Musk might be rethinking his promise to give away most of his fortune. This was reportedly due to his longtime friend Peter Thiel, who told the world’s richest man to withdraw from the Giving Pledge because his wealth could end up “in left-wing nonprofits chosen by Bill Gates.”

Thiel shared the story during a private lecture series in San Francisco in September. As noted in a Reuters report, Musk reportedly took Thiel’s suggestion seriously.

Thiel warned Musk about his fortune going to Gates-backed causes

Thiel said he even ran the math to make his point. By checking actuarial tables, he calculated that if Musk died within a year, his pledge would effectively direct $1.4 billion to Bill Gates. Musk reportedly said, “What am I supposed to do, give it to my children? You know, it would be much worse to give it to Bill Gates.”

Musk signed on to the Giving Pledge in 2012, two years after it was co-founded by Gates and Warren Buffett, as noted in a Daily Beast report. The initiative asks billionaires to donate the majority of their wealth to charitable causes either during their lifetime or through their wills. Gates’ foundation has focused on global health, education, and gender equality, areas Thiel has described as “left-leaning.”

Spokespeople for Thiel, Musk, and Gates have not issued a comment about the matter.

Elon Musk and Bill Gates

Thiel, who co-founded PayPal with Musk in 2000 before launching Palantir and becoming Facebook’s first outside investor, has maintained close ties to the Tesla and SpaceX CEO over the years. Musk, for his part, continues to donate through the Musk Foundation, which funds education, clean energy, and scientific research.

Elon Musk and Bill Gates’ relationship has taken a nosedive in recent years, especially amidst news that the Microsoft co-founder had taken a short bet against Tesla. Musk seemed to have taken Gates’ Tesla short personally, considering that the EV maker is fighting for sustainability, a cause that the Microsoft co-founder has supported. 

Gates has also been skeptical of Tesla’s projects such as the Tesla Semi, which Gates noted was not feasible due to the limitations of battery technology. More recently, the two billionaires butted heads when Gates claimed that the cuts initiated by Musk’s DOGE initiative would cost 2 million lives. In a post on X, Musk responded by stating that “Gates is a huge liar.”
