在目标检测界，一直有两个门派：
YOLO 派，传统豪强，走的是天下武功，唯快不破的路线。速度极快，是工业界、无人机、监控摄像头的绝对霸主。
Transformer 派，学院派贵族，脑子聪明精度极高，但由于算力消耗太大，过去像个林黛玉，在需要实时反应的场景里跑不动。

而但是，ICLR2026中RF-DETR 的出现，意味着 Transformer 派终于练成了凌波微步，它不仅保留了高智商，速度还跟上了实时要求。这就算直接不装了，开始抢 YOLO 赖以生存的实时检测饭碗了！

私以为，现在的RF-DETR三大绝活绝对惊艳：
第一个，火眼金睛。以前最顶级的保安看监控，100 个小偷能抓到 50 多个。这个新保安直接把业务能力提到了新高度，100 个里能稳稳抓出 60 多个，而且是在实时监控的超快车速下实现的。
还有，强大的领域适应性。很多 AI 都是偏科生，在学校考满分，去工厂、去农田、去医院就抓瞎。这个模型在 100 个完全不同的真实世界场景里考试都拿了高分。不管是看农田里的害虫，还是看医院的 X 光片，它都能无缝切换。
最重要的，成本。这东西有专门给手机、边缘芯片用的Nano，也有给超级计算机用的2XL。你预算多大，它就能变多大。

以后无人机跟踪、自动驾驶避让、工业流水线质检的大脑换代了。过去因为算力不够、反应太慢而无法使用的更聪明、更精准的 AI 架构，现在终于可以真正飞入寻常百姓家了。

[总裁简报 CEO Briefing @CEOBriefing]

北京。一位大学教授，独生女儿在美国安家立业，老伴去世后没几年他也去世了。女儿回来处理完后事，就回了美国，并把她父亲的房子挂在网上出售。房子被另一位大学教授购得，他在整理房子的时候发现老教授遗存的大量资料，包括他女儿从小到大的照片、日记本、书籍、画作等，都很有纪念意义，就给老教授的女儿打电话征求处理意见，回复道都不要了，让教授自行处理。

秋阳透过老杨树的叶子，在地板上洒下斑驳的光影。刚搬进来的周教授蹲在书房角落，指尖拂过积灰的纸箱，里面露出一张泛黄的儿童画，画里扎羊角辫的小女孩正举着奖状，旁边歪歪扭扭写着“爸爸真棒”。

周教授轻轻把画抽出来，画纸边缘已经发脆，背面却有一行钢笔字：“妞妞六岁画的，说要贴在我讲课的教案上，让学生看看她爸爸有多厉害。”字迹力透纸背，带着藏不住的骄傲。

纸箱里像藏着个时光博物馆：有扎着蝴蝶结的乳牙收藏盒，盒盖内侧贴着小纸条“妞妞掉的第一颗牙，哭了半宿，说要给牙仙子写信”；有厚厚的相册，每一页都贴着日期和注解，“三年级运动会，跑了倒数第一，却举着参与奖笑得最欢”；还有本上锁的日记本，钥匙就插在锁孔里，周教授犹豫了一下，还是转开了锁。

“1998年7月5日，爸爸今天淋雨回来，把给我买的奥数书裹在怀里，书没湿，他却发烧了。以后我要考清华，赚好多钱，给爸爸买辆能遮雨的车。”

“2003年10月12日，和爸爸吵架了，他不让我学画画，说没前途。可我就是喜欢啊……不过爸爸炖的排骨汤，还是很好喝。”

“2010年6月1日，拿到美国大学的录取通知书，爸爸偷偷抹眼泪了，还嘴硬说眼里进了沙子。妈妈说，爸爸昨晚翻出我从小到大的奖状，看了半宿。”

周教授翻着日记，指尖在“清华”两个字上顿了顿——听说老教授的女儿最后读了麻省理工，确实没走美术路。他往纸箱深处探了探，摸到个硬壳笔记本，翻开一看，是老教授的教学笔记，扉页夹着张机票，2015年的，北京飞纽约，旁边写着“妞妞结婚，请假15天，教案提前备好”。

笔记本里夹着不少便利贴，有的写着“妞妞爱吃红烧肉，明天炖一锅带过去”，有的画着简易地图，标注着“从机场到她家的路线”，还有张被茶水洇了角的，是张购物清单：“孙女的粉色奶瓶、带音乐的摇铃、妞妞爱喝的茉莉花茶”。

周教授突然想起打电话时，那位女儿的声音冷淡得像结了冰：“那些旧东西没用了，您扔了、烧了都行，别再打来了。”

他捏着那张购物清单，突然听见门口传来钥匙转动的声音——是快递送来了他网购的书架。安装时，一颗螺丝滚到纸箱旁，周教授弯腰去捡，却看见箱底压着个褪色的布偶，是只缺了只耳朵的小熊，脖子上系着的红绳都磨白了。

布偶肚子里塞着张纸条，是用铅笔写的，字歪歪扭扭，应该是小女孩的笔迹：“爸爸，小熊陪你睡觉，就像我陪在你身边一样。等我从美国回来，给你带巧克力。”

周教授把布偶抱在怀里，突然觉得鼻子发酸。他想起老教授的邻居说过，老先生晚年总坐在阳台发呆，怀里抱着个旧布偶，谁跟他说话都笑盈盈的，只是眼神空落落的。

傍晚时，周教授给老教授的女儿发了封邮件，附了张照片：夕阳下，那些照片、日记、布偶被一一摆在阳台上，秋风吹过，相册页轻轻翻动，像谁在低声诉说。邮件里写着：“这些不是旧东西，是一个爸爸攒了一辈子的牵挂。我给您寄到美国，或者，我替您好好收着。”

三天后，周教授收到了回复，只有一句话：“麻烦您寄过来吧，地址是……”后面跟着一串熟悉的美国地址，和教学笔记里那张机票上的地址，一模一样。

周教授打包时，特意把那只缺耳朵的小熊放在最上面。他仿佛能想象到，远在大洋彼岸的女儿打开箱子时，指尖触到小熊绒毛的瞬间，或许会突然想起，小时候坐在爸爸肩头，看他把自己的画小心翼翼贴满书房墙壁的模样。有些牵挂，就算隔着千山万水，就算藏了很久，也总会在某个瞬间，悄悄露出温热的棱角。

https://t.co/jgjk1NmDE1 2024 年的一些计划

1. 持续优化底层的模型和 RAG system，争取能够做到 state of the art
2. Devv for Teams，现在已经有非常多团队在使用 https://t.co/jgjk1NmDE1 了，这个 release 会进一步加速团队的研发效率

我们长期的愿景是用 AI 的方式 redefine developer tools，最终实现 level 5 级别的自动化软件开发。

搜索是我们切入到这个领域的第一步，先解决最轻量级但最刚需的场景，在做这件事的同时积累数据和训练模型。

为什么没有直接做 automated programming agent？

我们觉得当前的技术还没有完全达到，目前的 Agent 只能生成一些 demo 代码，完全没办法在线上场景使用。要实现这个愿景需要有一个非常长期并 sustainable 的商业化路径，只能生成 demo 代码在当前的资本市场是不可持续的，公司必须要有能力做到 default alive。

并且在 level 3 -> level 5 的过程中，需要持续积累数据和改进底层的模型。

这是一个非常有挑战的事情，但同时也非常令人兴奋，我们希望有更多的人加入到这个行业中来（即使不是加入我们）。

Here is one of the most easy-to-follow e2e tutorials, by Hubel Labs, of how to setup an advanced RAG pipeline over your data 👇

There are comprehensive diagrams showing you what the entire RAG pipeline looks like, from ingestion to retrieval. There is also a great visualization of what it looks like to decouple the indexed chunk vs. the synthesized chunk in our sentence window retriever technique.

And of course there's also a detailed Colab walkthrough.

It's fantastic and I highly recommend you check it out!

[Bill Ackman @BillAckman]

An update on @MIT Chairman Gorenberg and his wife's non-profit, https://t.co/rcEh7uG6RK.

This evening an email was forwarded to me from a friend who is an MIT alum which was intended to clarify MIT's involvement in https://t.co/rcEh7uG6RK. The forwarded email said the following:

"I read the recent posting by Bill Ackman on “MIT’s” donations to https://t.co/fMg1VVqNwz as indicated by the MIT 990PF.

The entirety of those donations were directed by Mark through the donor advised fund Mark created at MIT using his personal financial resources.

Other than the noted donations, MIT does not have a financial relationship with https://t.co/rcEh7uG6RK nor has MIT invested in it.

https://t.co/qGfBycdydM

I think the record should be set straight."

I am writing this post to set the record straight with the benefit of this new information.

I was incorrect in my original post that the source of the funding was the MIT Corporation. Rather, the funds that have been used to support Mr. Gorenberg's wife's non-profit, https://t.co/rcEh7uG6RK, were not from MIT's endowment or its corporate resources.

This was also confirmed in a Forbes article which appeared earlier today:

https://t.co/39F4qUucbe

in which the reporter writes:

"MIT told Forbes the donation to https://t.co/4dOX2C32hc came directly from Gorenberg through a donor advised fund."

It turns out that in 2018, MIT formed its own donor advised fund, the MIT DAF. Mr. Gorenberg and his wife are named in the press release for the MIT DAF's launch:

https://t.co/wNJKbvOs7Y

Donor Advised Funds DAF are 501(c)(3) entities that allow donors to contribute cash and/or appreciated securities and obtain an immediate tax deduction. The funds are invested by the DAF and grow tax free until the donor elects to make a donation. The donor retains the right to advise the DAF as to where the ultimate donations are made, subject to some important caveats.

From the IRS website: https://t.co/3J8TqCLkiC:

"Generally, a donor advised fund is a separately identified fund or account that is maintained and operated by a section 501(c)(3) organization, which is called a sponsoring organization. Each account is composed of contributions made by individual donors. Once the donor makes the contribution, the organization has legal control over it. However, the donor, or the donor's representative, retains advisory privileges with respect to the distribution of funds and the investment of assets in the account."

There are, however, important caveats according to the IRS https://t.co/3J8TqCLkiC:

"The IRS is aware of a number of organizations that appeared to have abused the basic concepts underlying donor-advised funds. These organizations, promoted as donor-advised funds, appear to be established for the purpose of generating questionable charitable deductions, and providing impermissible economic benefits to donors and their families (including tax-sheltered investment income for the donors) and management fees for promoters."

In this case, the Chairman of MIT made a donation to the MIT DAF, which in turn funneled the money to https://t.co/rcEh7uG6RK, the Founder, CEO, and CFO of which is his wife, and where Gorenberg serves as treasurer.

DAFs are only permitted to give to legitimate charities that don't afford a personal benefit to the individual or family of the individual who donated to the DAF.

https://t.co/rcEh7uG6RK received IRS approval to be a public charity, a community trust, in 2017. Had Mr. Gorenberg made his donation directly to https://t.co/rcEh7uG6RK instead of via the MIT DAF, https://t.co/rcEh7uG6RK would not have been able to sustain its status as a public charity because Mr. Gorenberg is https://t.co/rcEh7uG6RK's only donor. Public charities are required to have diversified donor bases, i.e., they must raise at least one-third of their funding from the general public.

Why is https://t.co/rcEh7uG6RK's status as a public charity important to Mr. Gorenberg?

The answer is that the amount of the deduction one can receive for a gift of cash to a public charity is double -- a 60% rather than a 30% deduction -- what you can deduct in a gift to a private foundation.

You can also offset a substantially greater amount of your adjustable gross income when giving to a public charity, 50% of AGI, rather than 30% in a gift to a private foundation.

DAFs are required to do careful due diligence on the charities they give to. They must make sure that the non-profit serves a legitimate charitable purpose, and that no personal benefit is being received by the donor to the DAF who directed the donation to the non-profit.

According to the MIT DAF website, the donor recommended grants "will be reviewed by the MIT Distribution Committee." I could not find any information about the Distribution Committee or its membership on MIT's website.

It does not appear that the MIT Distribution Committee did proper due diligence on https://t.co/rcEh7uG6RK, and/or received adequate disclosure. Alternatively, the MIT DAF made special exceptions for Chairman Gorenberg in donating to https://t.co/rcEh7uG6RK.

As I explained in yesterday evening's post, https://t.co/rcEh7uG6RK has only one full-time employee, Mr. Gorenberg's wife; it has never raised funds from anyone other than DAFs affiliated with Mr. Gorenberg; and it has never generated any revenues from its various DEI products and services. As importantly, it is not clear what charitable purpose https://t.co/rcEh7uG6RK serves.

The IRS is particularly concerned about the abuse of DAFs, and therefore imposes severe penalties for abusive transactions:

"Examinations of these arrangements may result in the following Service actions in appropriate cases:

disallow deductions for charitable contributions under Internal Revenue Code section 170 for payments to the fund;

impose section 4966 excise taxes on sponsoring organizations and managers of donor-advised funds;

impose section 4958 excise taxes on donors or managers of donor advised funds; and/or (d) deny or revoke the charity's 501(c)(3) exemption."

In other words, if the IRS found that the MIT DAF improperly donated to https://t.co/rcEh7uG6RK:

(1) the MIT DAF could lose its tax exemption,

(2) the DAF and the MIT Corporation, as sponsor and manager of the DAF, could become subject to excise taxes, and

(3) the deductions Mr. Gorenberg took in connection with the donations to the MIT DAF could be disallowed, and he could incur severe excise tax penalties.

As a general matter, the tax rules do not allow you to do indirectly what you are not permitted to do directly, and that is what appears to have happened here.

As MIT told Forbes: "the donation to https://t.co/4dOX2C32hc came directly from Gorenberg through a donor advised fund." [Emphasis added.]

Even MIT's understanding which it shared with Forbes is consistent with the facts which emerged upon my examination of these transactions. The MIT DAF was used as a conduit for Chairman Gorenberg to make a donation to his wife's charity that he could not have made directly. This enabled him to receive twice as large a tax deduction, 60% vs. 30%, and to shelter a greater percentage of his adjusted gross income, up to 50% of AGI versus 30%.

So the facts are not exactly as I understood them when I learned of them yesterday, but the substance is just as bad.

MIT's reputation and the tax status of the MIT DAF have been put at serious risk by its Chairman who received a inappropriate personal benefit by using the DAF to achieve substantial tax benefits for himself. And the MIT DAF is at risk of losing its tax exempt status and incurring severe excise tax penalties as a result.

Why would the MIT DAF make a donation to a questionable charity that was affiliated with its Chairman?

The MIT DAF Distribution Committee was either very sloppy, and/or it received inadequate disclosure about https://t.co/rcEh7uG6RK, or the Chairman used his apparent authority to cause the MIT DAF to consummate a transaction that would not have been approved in the ordinary course.

The funds went to a non-profit which promotes DEI ideology, which I have come to learn is not in society's best interests.

As a recent donor to MIT, and one, who up until very recently, was considering substantial additional donations to MIT (To that end, Ed Boyden of MIT's MediaLab made a very impressive presentation on neuroscience at our @PershingSqFdn board meeting just this week), I find all of the above very disturbing.
