Bitdeer unveiled its SEALMINER A3 series this week, marking the latest salvo in the intensifying competition among Bitcoin mining equipment makers. The lineup includes both air- and hydro-cooled models, with the top-end SEALMINER A3 Pro Hydro delivering 660 terahashes per second (TH/s) at 12.5 joules per terahash (J/TH). Bitdeer said the rigs “retain low-noise design while lowering power consumption per unit of hashrate,” a move aimed at large-scale operators. Mass production is slated for late September or early October. The release positions Bitdeer alongside Bitmain, whose Antminer S21 XP sets today’s efficiency bar, and ahead of Bitmain’s S23 series, expected in 2026 with sub-10 J/TH efficiency. Bitdeer has already energized 4.1 EH/s of A1 rigs and 27.8 EH/s of A2 rigs, deploying most for its own sites in the U.S., Norway, and Bhutan. In August, it mined 375 bitcoin, up 33% month-on-month. Forthcoming, Bitdeer is developing the SEALMINER A4, targeting 5 J/TH, and expanding U.S. production capacity.

OpenAI’s release of GPT-5 has reignited debate over whether large language models can ever stop inventing citations, Elizabeth Gibney reports in Nature. The San Francisco-based firm claims its newest model hallucinates less than predecessors, with error rates on citation benchmarks dropping significantly. On the LongFact test, for instance, GPT-5 hallucinated just 0.8% of claims with web access, compared to 5.1% for OpenAI’s reasoning model o3. Yet researchers caution that “eliminating hallucinations entirely is likely to prove impossible,” says Mushtaq Bilal of Silvi. Independent tests show rival models like Google’s Gemini 2.0 sometimes perform better, though all major systems now err less than 1.5% when summarizing. OpenAI is rewarding GPT-5 for honesty and exploring confidence-calibration methods. As Purdue’s Tianyang Xu notes, the improvements are “acceptable to users” in many cases, but reliability in technical domains remains a hurdle.

Giorgi Bachiashvili, once a close aide to Georgian billionaire and former prime minister Bidzina Ivanishvili, is serving an 11-year prison sentence after being convicted in May of misappropriating nearly 9,000 bitcoin, valued at $43 million, and laundering the proceeds, Protos reports. Bachiashvili fled to Abu Dhabi mid-trial but was arrested after publicly alleging he was targeted for opposing Russia’s war in Ukraine. His mother has described him as Ivanishvili’s “personal prisoner,” claiming he has been beaten in custody, while Transparency International called the conviction “devoid of both legal and factual grounds.” Georgia’s Prosecutor’s Office maintains he used financial maneuvers to disguise the bitcoin’s origin. Authorities have since frozen family bank accounts and opened new investigations. With critics saying Ivanishvili exerts near-total control over Georgia’s justice system, European institutions may come under pressure to scrutinize what some describe as politically motivated persecution.

China’s State Administration for Market Regulation (SAMR) has issued a preliminary finding that Nvidia violated the country’s antitrust law by failing to meet conditions tied to its 2020 acquisition of Mellanox Technologies. The $6.9 billion deal was key to Nvidia’s rise in data centers and high-performance computing, markets where it now dominates. SAMR’s statement coincides with U.S.–China trade talks in Madrid, with a tariff truce set to expire in November, and people familiar with the matter suggested Beijing timed the announcement to increase leverage in the upcoming negotiations. The probe, launched in December after Washington imposed tighter chip export controls, included extensive interviews and legal reviews. Nvidia, already under pressure in China where regulators discourage purchases of its H20 AI chip, did not immediately comment. The ruling underscores rising geopolitical tension in the semiconductor industry.
