VLMs are selectively blind — they decide how much to look at an image based on question framing (open-ended vs Yes/No vs MCQ), even when the same visual reasoning is required.

New comment by ritwikgupta in "FedRAMP 20x – One Month in and Moving Fast"

ritwikgupta — Tue, 13 May 2025 01:19:36 +0000

This is about changing the way FedRAMP accreditation is done for any cloud service, like Box (or a new SaaS that you may create tomorrow). The FedRAMP process requires you go through a certain set of audits, meet a certain set of standards, etc., in order to be approved to host CUI (IL4/5) or SECRET (IL6) information.

Normally this can take a lot of time and monetary investment. On one hand, these processes encode cybersecurity best practices. On another hand, it keeps new companies out of the market.

It seems this effort is doing away with a lot of those processes. I hope the level of compliance stays the same.

Public trust is not a security clearance; it is simply a more involved background check. A security clearance is only granted after a T3/T5 investigation and adjudication of the request. The SF312 NDA signed in order to receive your clearance does not expire.

With the recent veto of SB 1047, it becomes even more important to ask why these proposed policies are lacking. We suggest that all modern AI regulations are overly broad and flawed because they miss the most important part of AI capabilities: data.

Do you have an example of this workflow? Are you developing outside of XCode on a non-macOS platform in Swift and then essentially compiling and packaging using GitHub Actions?

Fascinating. The massive variance in the percentage of chickens that prefer roosting off the ground is interesting. I wonder what environmental pressures drives this decision.

New comment by ritwikgupta in "DOJ: Man sentenced to 14 years for posession of deepfake CSAM"

ritwikgupta — Sat, 18 May 2024 16:54:34 +0000

1. The PROTECT Act provisions have repeatedly been upheld by both appellate the Supreme Court as constitutional as long as the CSAM in question meets the Miller or Ferber standards. Either the law is constitutional, or you’re proposing that the courts are illegitimate, the latter of which is conspiratorial.

2. You are right that there is a campaign to limit access to open source generative AI models, but it is not an initiative led by the government. Companies such as OpenAI, Anthropic, and Google are leading the charge when it comes to emphasizing the danger of open source models and are lobbying every day to limit access. The executive and legislative branches are following suit with what industry executives tell them because they are deferred to as experts.

Industry policy teams have invented vague, ill-defined terms such as “frontier models” and equate these models as having the same power as nuclear weapons. They have a vested interest in being the sole controllers of this technology.

If you want to counter governmental efforts to limit access to such models, start by countering the FUD pushed by industry in this space.

You are grossly under-estimating the ability of the FBI’s cyber forensics teams to discern whether or not data was planted maliciously or produced overtly, as well as under-estimating the ability of the courts and a jury to understand when someone is willingly producing CSAM versus accidentally being in possession.

This prosecution is the first of its kind for the DOJ. It is highly unlikely that they would pick this case to take to trial if there was not certainty about the actions the perpetrator engaged in.

This is a misinformed and incorrect take. The PROTECT Act of 2003 [0] makes it illegal to possess CSAM that is generated by superimposing faces of minors onto sexually explicit imagery, or vice versa.

This bill predates generative AI models by decades. There is no need to engage in conspiracy theories here — the law is clear that this kind of imagery is illegal.

The old search was much better than the new search. The new search can never find exact strings in my repos, even when I have copy-pasted those strings from my repo to the search bar!

Apple may already be headed in that direction. They already have unified CPU and GPU RAM. It doesn’t seem far-fetched to imagine that they could unify persistent storage and memory.

Military contracts are posted and solicited publicly. There's no "dark" acquisition of the type that you are suggesting. You can look up if OpenAI has any contracts with the DoD at [0]. They do not.

Out of curiosity, are you a Christian who observes Lent? Many of my Christian friends do not consider fish to be “meat” as that is not allowed during Lent, but fish is allowed, therefore fish != meat.

This is survivorship bias. No counterexamples emerge because successful and working capabilities can’t and won’t be shared? Not until declassification of those sources kicks in.

The government should not give up powerful intelligence tactics, techniques, and procedures solely because the general public has a want to know. We have elected representatives with clearances for those purposes.

There’s no feeling of power here. I took on this role because the FBI needs people to help them answer these hard questions, and your traditional Silicon Valley crypto bros won’t help.

I was raised in this country post-9/11 and was taught to fear the FBI. I grew up strongly critical of our surveillance state and the overreach of power that was reported upon. The FBI hosting a deeply critical voice inside to help provide insight to their processes seems like a pretty just thing to me.

If you have better ideas, then I invite you to help change the institution. Come “be in on the secret” (a security clearance to guard national intelligence?) and do the right thing.

No, this is a misconception. The FBI is not just a law enforcement agency. It is also an intelligence agency.
