Tesla Giga Berlin meeting highlights works council stress, 65,000 lost mugs
A recent staff meeting at Tesla’s Gigafactory Berlin-Brandenburg highlighted union pressure following the company’s latest works council election, along with as many as 65,000 mugs that have disappeared from the plant.
During a staff meeting a few weeks ago, Tesla Giga Berlin Director of Manufacturing Andre Thierig said that as many as 65,000 mugs had disappeared from the plant since it began production in March 2022, according to the German publication Handelsblatt, which obtained audio recordings of the meeting.
“I’m just going to give you a figure,” Thierig said during the meeting, which took place on July 4 (via DW). “We’ve bought 65,000 coffee mugs since we started production here. 65.000! Statistically speaking, each of you already has five Ikea coffee cups at home.
“I’m really tired of approving orders to buy more coffee cups,” he added, to which employees laughed and applauded.
At the time of writing, Thierig has not yet responded to Teslarati’s request for comment on the mugs, though he did reference the original story in a recent post on his LinkedIn page. Rather, he directed away from the media’s recent attention on the mugs, and instead toward Giga Berlin’s new Giga Gym for employees.
“Whilst the whole world thinks we are only busy with mugs, we actually care about the most important asset of our Gigafactory – our people,” Thierig wrote in the post. “We listened to their feedback and finally finished our newest employee facility.
“Today, we celebrated the pre-opening of our Giga Gym! Surely one of the coolest spots in the entire factory. Great design and great work by all involved teams. It is going to be fun!”
Tesla Giga Berlin’s expansion plan remain a divisive topic in Grunheide
The Handelsblatt report also shared details regarding Giga Berlin’s recent works council election held in March, another item addressed in the recorded meeting. Since then, some at the factory have expressed negative sentiments toward union IG Metall, including re-elected Works Council Head Michaela Schmitz.
“I’m trying to put it charmingly,” Schmitz said during the meeting. “Unfortunately, we have members of the works council here who tend to allow themselves to be exploited by the union from outside.
“And they’re trying to assert the interests of the union along the way. In the end, of course, this prevents us from achieving great results for you again.”
The news comes after IG Metall candidates secured the most seats in the March works council election, but not enough to be a majority.
IG Metall’s candidates gained 3,516 votes in the election, while candidates from a rival group called Giga United garnered 3,201 votes. A third group, dubbed One Team, landed 1,106 votes. Thierig went on to thank employees for having such a high voter turnout, and for opting not to unionize Giga Berlin.
“In the works council election that has just ended, the majority of our workforce spoke out against a trade union works council,” he wrote in a LinkedIn post. “I would like to thank all employees for a high voter turnout of almost 80% and their vote for an independent future for the Gigafactory of Berlin-Brandenburg. We will continue to master all challenges together in the future.”

Elon Musk’s xAI brings 1GW Colossus 2 AI training cluster online
Elon Musk shared his update in a recent post on social media platform X.
xAI has brought its Colossus 2 supercomputer online, making it the first gigawatt-scale AI training cluster in the world, and it’s about to get even bigger in a few months.
Elon Musk shared his update in a recent post on social media platform X.
Colossus 2 goes live
The Colossus 2 supercomputer, together with its predecessor, Colossus 1, are used by xAI to primarily train and refine the company’s Grok large language model. In a post on X, Musk stated that Colossus 2 is already operational, making it the first gigawatt training cluster in the world.
But what’s even more remarkable is that it would be upgraded to 1.5 GW of power in April. Even in its current iteration, however, the Colossus 2 supercomputer already exceeds the peak demand of San Francisco.
Commentary from users of the social media platform highlighted the speed of execution behind the project. Colossus 1 went from site preparation to full operation in 122 days, while Colossus 2 went live by crossing the 1-GW barrier and is targeting a total capacity of roughly 2 GW. This far exceeds the speed of xAI’s primary rivals.
Funding fuels rapid expansion
xAI’s Colossus 2 launch follows xAI’s recently closed, upsized $20 billion Series E funding round, which exceeded its initial $15 billion target. The company said the capital will be used to accelerate infrastructure scaling and AI product development.
The round attracted a broad group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group. Strategic partners NVIDIA and Cisco also continued their support, helping xAI build what it describes as the world’s largest GPU clusters.
xAI said the funding will accelerate its infrastructure buildout, enable rapid deployment of AI products to billions of users, and support research tied to its mission of understanding the universe. The company noted that its Colossus 1 and 2 systems now represent more than one million H100 GPU equivalents, alongside recent releases including the Grok 4 series, Grok Voice, and Grok Imagine. Training is also already underway for its next flagship model, Grok 5.

Tesla AI5 chip nears completion, Elon Musk teases 9-month development cadence
The Tesla CEO shared his recent insights in a post on social media platform X.
Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk.
The Tesla CEO shared his recent insights in a post on social media platform X.
Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.
This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.
