Google Unveils Gemini 2.5 Pro, Its Latest AI Reasoning Model With Significant Benchmark Gains
Published on March 26, 2025 at 01:00AM
Google DeepMind has launched Gemini 2.5, a new family of AI models designed to "think" before responding to queries. The initial release, Gemini 2.5 Pro Experimental, tops the LMArena leaderboard by what Google claims is a "significant margin" and demonstrates enhanced reasoning capabilities across technical tasks. The model achieved 18.8% on Humanity's Last Exam without tools, outperforming most competing flagship models. In mathematics, it scored 86.7% on AIME 2025 and 92.0% on AIME 2024 in single attempts, while reaching 84.0% on GPQA's diamond benchmark for scientific reasoning. For developers, Gemini 2.5 Pro demonstrates improved coding abilities with 63.8% on SWE-Bench Verified using a custom agent setup, though this falls short of Anthropic's Claude 3.7 Sonnet score of 70.3%. On Aider Polyglot for code editing, it scores 68.6%, which Google claims surpasses competing models. The reasoning approach builds on Google's previous experiments with reinforcement learning and chain-of-thought prompting. These techniques allow the model to analyze information, incorporate context, and draw conclusions before delivering responses. Gemini 2.5 Pro ships with a 1 million token context window (approximately 750,000 words). The model is available immediately in Google AI Studio and for Gemini Advanced subscribers, with Vertex AI integration planned in the coming weeks.

Slashdot: Battery Fires At Recycling Centres Are Costing the UK £1bn a Year

Battery Fires At Recycling Centres Are Costing the UK £1bn a Year Published on 2026-08-23T00:29:00Z Wrongly discarded lithium batteries, such as those in vapes, are causing more than 10 fires a week at U.K. recycling centers, according to figures shared with the Guardian: The Environment Services Association (ESA), the trade body for waste management companies, said its members had reported 1,518 fires in the year to March 2026. At least 541 of these fires were directly attributed to lithium ion batteries, the survey found. There were a further 216 battery fires in bin lorries [garbage trucks]. The ESA said the reported number of battery-related fires underestimated the scale of the problem, because in most incidents it was impossible to determine the cause of the blaze. A spokesperson said: "We know 40% of fires at recycling centres are caused by batteries, but we think the actual number is more like 70%." It estimates that annual cost of these fires has increased from ...

Slashdot: How the FSF Sysadmins are Blocking Botnets with reaction

How the FSF Sysadmins are Blocking Botnets with reaction Published on 2026-07-11T21:47:00Z For nearly two years the Free Software Foundation has been fighting web crawlers (including many aggressively scraping training data for AI models). A botnet controlling about five million IPs hit one system for six months in 2025. Their systems administrator wrote this week that they view these as distributed denial-of-service attacks. How are they fighting back? We noticed patterns in the scrapers that were abnormal, which gave us material for writing regular expressions. Searching for the regular expression then gave us a large lists of IP addresses. Looking up the origin of those IP addresses revealed that some of the crawlers were using botnets of residential IP addresses to scrape faster and avoid detection. We looked for what kinds of botnets might be generating the kind of traffic that we were seeing, and one that we suspected was called the "Vo1d" botnet, comprised of sma...

Slashdot: AT&T Outlines $250 Billion US Investment Plan To Boost Infrastructure In AI Age

AT&T Outlines $250 Billion US Investment Plan To Boost Infrastructure In AI Age Published on 2026-03-10T20:00:00Z AT&T plans to invest more than $250 billion over the next five years to expand U.S. telecom infrastructure for the AI age. The company says it will also hire thousands of technicians while partnering with AST SpaceMobile to extend coverage to remote areas. Reuters reports: Rapid adoption of artificial intelligence, cloud computing and connected devices has prompted telecom operators to invest heavily in fiber and 5G networks as they also seek to fend off intensifying competition from cable broadband providers. AT&T, which has about 110,000 employees in the U.S., said the new hires will help build and maintain its infrastructure. The outlay includes capital expenditure and other spending, the company said. The spending will focus on expanding its fiber and wireless networks, including accelerating deployment of fiber broadband, 5G home internet and satellite co...
