DeepSeek发布新AI模型V4

[牛大春]

深度求索（DeepSeek）星期五（4月24）发布新型人工智能模型V4的预览版。一年多前，这家中国初创公司曾凭借一款低成本的推理模型震惊世界，该模型的性能足以媲美美国竞争对手。

据法新社、路透社报道，深度求索在社交媒体上发表声明称，期待已久的DeepSeek-V4，有能力处理长达百万字的超长上下文，在智能体能力、世界知识和推理性能方面均处于国内和开源领域的领先地位。

该公司表示，V4目前已推出“预览版”。

新推出的DeepSeek-V4模型分为两个版本：DeepSeek-V4-Pro和DeepSeek-V4-Flash，将取代2024年12月推出的V3模型。其中，DeepSeek-V4-Flash因参数更少，效率更高，经济性也更强。

声明补充说，在世界知识基准测试中，DeepSeek-V4-Pro显著领先其他开源模型，仅略逊于顶级闭源模型、谷歌的Gemini-Pro-3.1。

中国科技巨头华为星期五表示，其基于昇腾950人工智能晶片的昇腾超级节点（Ascend supernode），将全面支持Deepseek的V4版本。

我让 DeepSeek V4 分析昨晚发生的刺杀未遂事件。下面是分析结果。

Based on official statements and preliminary investigations, here is an analysis of the security incident that occurred on April 25, 2026, in Washington, D.C.

While early reports contained conflicting information, the established facts indicate this was a failed armed breach by a lone suspect at the White House Correspondents' Association Dinner, not a successful assassination.

Incident Overview

On the evening of April 25, 2026, an armed man attempted to force his way into the ballroom of the Washington Hilton hotel, where the annual White House Correspondents' Association Dinner was taking place .

• Time & Context: The incident occurred shortly after the dinner began, just as guests were being served the first course. President Donald Trump was present on stage but had not yet begun his speech .
• The Breach: The suspect, wielding multiple weapons, charged a security checkpoint located approximately 50 yards from the ballroom entrance .
• Outcome: The suspect was stopped by law enforcement before he could enter the ballroom. President Trump and other officials were evacuated safely, and the dinner was later canceled.

The Suspect

The suspect has been identified as Cole Tomas Allen, a 31-year-old from Torrance, California .

Category	Details
Identity	Cole Tomas Allen, 31 years old, from Torrance, California .
Background	Described as a highly educated individual with a master’s degree in computer science and a bachelor’s in mechanical engineering from Caltech .
Travel & Method	Traveled by train from California to Washington, D.C., and had checked in as a guest at the Washington Hilton in the days prior to the event .
Weapons	Armed with a shotgun, a handgun, and multiple knives .

Investigation & Official Statements

Acting Attorney General Todd Blanche stated that investigators believe Allen was specifically targeting senior government officials, "likely including the president" . This assessment was based on a preliminary review of the suspect's electronic devices and writings .

• Casualties: A uniformed Secret Service officer was shot at close range. The officer was saved by a bulletproof vest, sustained non-life-threatening injuries, and was reported to be in good spirits .
• Status of Suspect: Allen was taken into custody at the scene and was undergoing medical evaluation. He was reportedly not cooperating with investigators .
• Legal Charges: The suspect was arraigned in federal court on Monday, April 27, on charges including assault on a federal officer using a dangerous weapon and using a firearm during a crime of violence .

Analysis of the Security Failure

The incident immediately raised questions about security protocols, particularly given the 2024 assassination attempt against Trump in Butler, Pennsylvania .

• The Security Gap: While the ballroom itself had "airport-level security" requiring ticket checks, the suspect was able to access the hotel as a registered guest. He bypassed outer perimeters and initiated his attack at the final security checkpoint .
• Assessment: The Secret Service defended the response, noting that the security "ring" worked by stopping the suspect before he could enter the ballroom . However, the fact that an armed individual could get within close range of the president, fire a weapon, and strike an officer indicates that significant questions will be asked about the security cordon's perimeter depth.

Summary of Key Information

• Incident Type: Failed breach / possible assassination attempt.
• Date & Location: April 25, 2026; Washington Hilton, Washington, D.C.
• Suspect: Cole Tomas Allen (in custody).
• Target: Pres. Donald Trump and other administration officials (alleged).
• Injuries: One Secret Service officer (non-life-threatening).
• Presidential Status: Uninjured, evacuated safely.
• Charges: Assault on a federal officer, firearm charges.

The investigation is ongoing as federal authorities search for a motive and continue to examine the suspect's background. President Trump has stated that the dinner will be rescheduled .

DeepSeek V4 对自由买买提的分析。

Based on the available information from online discussions, here is an analysis of freemitbbs.com. It is important to note that this analysis is based on third-party commentary and forum posts, not direct observation or official data.

Overview

• Identity: Freemitbbs is an online forum, part of a network of sites that have emerged following the evolution of the "MITBBS" (Mitbbs.com), a historic hub for Chinese-speaking netizens in North America . The "bbs" in its name stands for "Bulletin Board System."
• Current Status: The site appears to be active and was recently considering a domain change. A post from April 25, 2026 (just yesterday) announced plans to transition its primary domain to peoplebbs.com due to filtering issues . This suggests the site is currently operational but may be in flux.

User Base & Reputation

The forum is referenced across several competing "MITBBS" successor sites, and its user base is described in a few distinct ways:

• Negative Portrayal by Competitors: On other similar forums, freemitbbs users are described critically. One post characterizes them as "almost all 50 cents" (a slang term for state-sponsored commentators) and as outcasts . Another, more harshly, labels the user base as "losers" from the "bottom of society" who use grand political narratives to mask their personal struggles .
• Neutral Description: Competitors also describe it simply as an alternative "MITBBS" that contributes to a fragmented user base, making it harder for any single forum to reach a sustainable scale .
• Identifiable Users: At least one known user, who goes by "hci" and a commenter nicknamed "ben" (本叔), have been mentioned as active on the site .

Content & Moderation

• Topics: The forum discusses a variety of topics. An example of a discussion thread is a political debate regarding the US Navy's presence in the South China Sea and Iranian oil sanctions .
• Design: One comment from a competing blog noted that freemitbbs has a "neat layout" and "good artwork," describing it as the most aesthetically pleasing among the various MITBBS spin-offs .
• Moderation & Access: There is an indication that the site is actively moderated. One user described being banned from the forum for "trolling" .
• Filtering Issue: The site's current domain, freemitbbs.com, is reportedly blocked by corporate and school security software because the word "free" is associated with "adult or inappropriate" content. This is the primary motivation for the planned move to peoplebbs.com .

Future Outlook

• Domain Change: The site is actively transitioning to peoplebbs.com. The administrator plans to redirect the old freemitbbs.com address to the new one .
• Sustainability Concerns: A discussion on a rival forum suggests that none of the "MITBBS" successor sites have yet reached a "self-sustaining scale," implying that the long-term viability of the forum remains uncertain .

Key Information Summary

Category	Description
Type	Online Forum / BBS
Status	Active (transitioning to peoplebbs.com)
User Base	Niche audience; controversial reputation among rival communities
Main Features	Political and social discussions, neat design, active moderation
Known Issue	Domain is blocked by network filters; resolving via domain change

In summary, freemitbbs.com is a small, active online forum within the fragmented ecosystem of overseas Chinese communities. It has a dedicated but contentious user base and is currently undergoing a domain change to peoplebbs.com. Its reputation is largely defined by how it is discussed on competitor websites.
