https://xbench.org/ 2. github: https://github.com/xbench-ai/xbench-evals 3. huggingface: 三周前,我们正式推出了xbench,一款致力于量化AI系统在真实场景的效用价值,以及采用长青评估机制 的AI基准测试。 这期间,从大厂到创业公司,从大模型研究者到AI Agent开发者,我们收到了来自海内外的大量咨询,特别 是希望使用xbench评测集对他们的产品进行测试的需求与日俱增。 把红杉投资团队进行内部测评的工具打造成一款公开的AI基准测试,用公开透明的方式吸引更多AI人才和 项目的共创,是我们打造xbench的初衷。我们相信开源精神可以让xbench更好地进化,为AI社群创造更大的 价值。 因此,红杉中国今天正式开源xbench的两个评测集xbench-ScienceQA和xbench-DeepSearch。未来,我们将基 于大模型和AI Agent的发展情况不断动态更新评测集,并且采用"黑白盒"机制,既保证xbench的发展可以服 务更多的大模型和Agent开发者,同时尽力避免静态评测集经常出现的过拟合问题,确保xbenc ...

Core Viewpoint - The recent regulatory changes in the public fund industry aim to enhance the quality of equity funds through floating fee rates and performance-based compensation reforms, leading to a significant reshaping of the market dynamics [1][2]. Fee Rate Reform - The new regulations mandate that actively managed equity funds adopt a floating fee rate model linked to performance benchmarks, effectively ending the previous model that prioritized scale and management fees [2][4]. - Funds that underperform by more than 3% relative to their benchmarks will see their management fees reduced from 1.2% to 0.6%, while those that outperform by 6% or more can increase fees to 1.5% [3][4]. - The average return of equity mixed funds was reported at 12.32%, with only 26.9% of funds outperforming their benchmarks by 6%, indicating increased pressure on fund managers to focus on performance [4][5]. Performance Evaluation and Growth Targets - The new rules also require public funds to increase their holdings in A-shares by at least 10% annually over the next three years, with a focus on boosting the proportion of equity funds, which currently lags behind global averages [5][6]. - The performance evaluation system will now place greater emphasis on long-term returns, with at least 80% of the assessment based on three-year performance [7][8]. Manager Compensation Changes - Fund managers' compensation will be closely tied to fund performance, with significant reductions in pay for those whose funds underperform their benchmarks by over 10% over three years [8][9]. - The new regulations aim to correct past issues of inadequate risk control and style drift by emphasizing the importance of performance benchmarks [9]. Industry Restructuring - The reforms are expected to lead to a major reshuffling in the fund industry, favoring top-performing firms and potentially disadvantaging smaller players who may struggle to adapt [12][14]. - The introduction of a fast-track registration mechanism for ETFs is anticipated to enhance the appeal of index funds, which may see increased demand as a result of the new performance-focused evaluation [12]. Investment Strategy Shifts - Fund managers may increasingly allocate to sectors that are underrepresented in their benchmarks to avoid underperformance, particularly in dividend-paying sectors [10][11]. - The focus on diversified asset allocation and risk management will become more critical, moving away from reliance on past performance of individual funds [9][12].

【特稿】英国4月对美货物出口大降 创1997年以来单月最高跌幅

英国4月对美货物出口大降 创1997年以来单月最高跌幅 英国国家统计局公布的贸易数据显示,英国整体货物贸易赤字从3月的199亿英镑(约合270亿美元)扩 大至4月的232亿英镑(约合315亿美元)。 沈敏 英国国家统计局12日公布4月份经济数据,显示英国当月对美货物出口下降20亿英镑(约合27亿美 元),创1997年开始记录相关月度数据以来最大单月跌幅。经济学家认为,这反映美国政府关税政策所 致冲击。 路透社报道指出,在美国总统唐纳德·特朗普4月2日宣布对美国所有贸易伙伴开征所谓"对等关税"后, 英国是最先与美国达成新贸易协议的主要经济体,该协议使英国免于被美国征收高达50%的钢铝产品关 税而维持25%税率,但英国所有输美产品仍需缴纳10%的所谓"基准关税"。 英国经济研究机构安永统计俱乐部首席经济顾问马特·斯旺内尔分析:"美国贸易政策的拖累叠加了一系 列国内逆风因素,包括财政政策大幅收紧、过往几次升息决策影响传递滞后等。"导致GDP增速下降的 一大国内因素是英国政府4月起结束购房印花税临时优惠政策影响房市表现;另一因素是英国汽车制造 业产出以及对美国和欧洲联盟出口下降。 据路透社报道,面对通胀水平居高不下、 ...
