Trump orders US agencies to stop use of Anthropic technology amid dispute over ethics of AI Hours after exclusion of Anthropic, OpenAI announces fresh Pentagon deal, but says it will maintain same safety guardrails at the heart of the dispute

One thing I can absolutely guarantee:

This is not a dispute over “ethics of AI.” It’s not a dispute over “guardrails.”

It’s about power.

We advocate for the silent phase as potentially the MOST IMPORTANT stage of AI translation because it gives you specific, local evidence for performance in your setting. And we can do them better than how we are now - this means less wasteful translation and research, and more reliable evidence

Some devices approved by regulators had substantial performance drops in new settings. Thankfully, these papers described SILENT evals - so, they found out the tool was worse than the status quo before they changed patient care!

Major gaps concern failure case analysis, fairness, and clinical verification of outputs.

You know, the stuff that is most important to clinicians calibrating their use of the tool 😳

So what is a “silent trial”?

Apparently, everyone has a different definition (just ask our reviewers 🤭)

We made a taxonomy in Table 1 to promote consistency

👀 check out our new paper!

We performed a scoping study re published practices in silent evals for AI/ML tools - everything from hospital-based prediction algos to regulatory-approved medical devices

Baffling how many AI-pushers still arguing “well, humans make mistakes all the time!” It’s like, uh yes, well done on that utterly scintillating observation, but perhaps the KIND of errors matters somewhat, no?

Unpopular opinion: claiming that“human-in-the-loop” is your governance of AI is the equivalent of claiming drinking orange juice is your governance of not getting a cold

it is worth remembering that cigarette companies also spent decades selling products they knew would harm and kill people and marketed them specifically to young people to create dependence. let's stop this without having to go through a generation of death and several class actions.

The worse part though is that as their costs go up for adding these nonsense features, they inevitably offload it onto us, the consumers. 😡 I’m now looking into old school options again to get away from this stuff.

And the fact that they even think this is possible shows they have absolutely zero understanding of any concepts and principles related to “bias” 🤨 If they cannot understand the very concepts they invoke, then they have zero credibility to address the problem and should sit this one out.

Not arrogant - 100% accurate. The very fact that these folks can switch up their buzz words on a dime shows they don’t understand the words in the first place.

I've yet to see a single discussion of "Canadian digital sovereignty" include any Indigenous experts, at best we're given a token mention that at some point they'll "consult with Indigenous Peoples" like we're some sort of monolith. Umm, y'all need to consider all our lands, and our distinctiveness.
