With <strong>2.8 trillion parameters<\/strong>, Kimi K3 is significantly larger than previous open-source benchmarks, such as DeepSeek\u2019s 1.6 trillion-parameter model. The startup reports that K3 outperforms <strong>Anthropic\u2019s Claude Opus 4.8<\/strong> and <strong>OpenAI\u2019s GPT-5.5<\/strong> in specific coding and reasoning benchmarks, signaling that Chinese developers are rapidly closing the &quot;frontier gap&quot; with American counterparts like <a href=\"https:\/\/stockmarketwatch.com\/stock\/MSFT\" data-internallinksmanager029f6b8e52c=\"18\" title=\"Stock: MSFT\">Microsoft<\/a> (<a href=\"\/stock\/MSFT\">MSFT<\/a>) and Alphabet (<a href=\"\/stock\/GOOGL\">GOOGL<\/a>).<\/p>\n<p>The model features a <strong>1 million-token context window<\/strong> and utilizes a &quot;Stable LatentMoE&quot; architecture to improve computational efficiency. While Moonshot AI admits K3 still trails the most advanced proprietary systems in overall performance, the release has sent shockwaves through the industry. The full weights for the model are scheduled for public release on <strong>July 27, 2026<\/strong>, which could democratize access to frontier-level intelligence for global developers.<\/p>\n<h2>U.S. Imposes Strict Four-Year Limit on Student Visas<\/h2>\n<p>The <strong>Trump administration<\/strong> has finalized a major immigration policy shift, eliminating the &quot;duration of status&quot; loophole for international students. Under the new <strong>DHS<\/strong> rule, <strong>F, J, and I visa holders<\/strong> will be limited to a fixed <strong>four-year stay<\/strong>, after which they must undergo a rigorous vetting process, including <strong>biometric and background checks<\/strong>, to secure an extension. The administration cited the need to prevent &quot;visa abuse&quot; and ensure foreign students return home after completing their primary studies.<\/p>\n<p>This regulation is expected to hit students from <strong>South Korea, China, and India<\/strong> the hardest. In South Korea alone, more than <strong>13,000 students<\/strong> currently in the U.S. will be affected. Educational institutions have expressed concern that the rule will disrupt long-term academic programs, such as <strong>doctoral degrees and medical residencies<\/strong>, which typically exceed the four-year threshold. The rule is set to take effect in <strong>September 2026<\/strong>, roughly 60 days after its publication in the Federal Register.<\/p>\n<h2>Oil Volatility and Geopolitics Drive Currency Markets<\/h2>\n<p>The <strong>Canadian Dollar<\/strong> remains resilient, trading near the <strong>1.4035<\/strong> level against the <strong>U.S. Dollar<\/strong>, supported by a &quot;geopolitical risk premium&quot; in the energy markets. Crude oil prices have stabilized near one-month highs as the <strong>U.S. carried out air strikes<\/strong> against Iranian infrastructure, and Iran responded by targeting U.S. military facilities. These tensions have led to the closure of the <strong>Strait of Hormuz<\/strong>, a critical artery for global energy supplies, providing a natural buffer for the oil-sensitive &quot;Loonie.&quot;<\/p>\n<p>Despite the strength in oil, the <strong>U.S. Dollar Index (DXY)<\/strong> held steady at <strong>100.72<\/strong> as investors sought the greenback as a safe-haven asset. Market participants are currently balancing soft U.S. inflation data\u2014which suggests the <strong>Federal Reserve<\/strong> may pause further rate hikes\u2014against the inflationary pressure of rising energy costs. Analysts at <strong>Societe Generale<\/strong> noted that while the <strong>Bank of Canada<\/strong> is expected to hold rates at <strong>2.25%<\/strong>, the resilient domestic economy and high core inflation keep the door open for a potential year-end tightening.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Key Takeaways Moonshot AI launched Kimi K3, the world\u2019s largest open-source
