Good. The dataset of counterfactuals we used has been out there for a while and I'm not surprised things have been "fixed" . The question is "how this was done" and if it can be generalized to any similar cases in the future. Unfortunately many of these things can't be verified with closed models.
010
Luca Rossi @lrossi.bsky.social · 10/09/2026
You can tests it yourself. With some differences these models are largely similar and I'd expect to operate in similar way. Nevertheless, there are many strategies in which this can be fixed in commercial models and they don't offer the same level of transparency needed for what we wanted to test.

Luca Rossi @lrossi.bsky.social · 10/09/2026
This holds across model types and sizes (for what we could test). Even more interesting is that the model is "sure and confident" about the wrong answer. Considering how VLLMs are being positioned more and more as consumer products in a number of devices (e.g. wearables) these results are

at #ECCV. By using using sequence-level margins, PMI correction, token-step margins, and entropy diagnostics they show how models consistently fall back on their textual prior when confronted with counterfactual visuals. To say it clearly, the model will count 4 legs even if your your camel has 5.

"willing" is at least debatable. This agreement doesn't introduce anything that wasn't there in some form before. In the meantime it takes no responsibility or accountability for the content or the business model it supports while delegating full responsibility (and conflicts) to families.

If you're Meta this is a great move, you still don't take any responsibility, you delegate that to the families while limiting your interventions to things that were largely already there. If you're everyone else, you'll have to keep waiting.

we (as a society) missed a huge opportunity but we managed to placate the actual anxious generation — not teens, but the parents whose anxiety this was designed to soothe. With few exceptions, everything that is dangerous and problematic for a teenager is dangerous and problematic for a grown up.

Most of what Meta committed to in this settlement was already available, and what's new still just delegates the conflict — and the responsibility — to families. But that's not even the worst part. The worst part is that by framing this as a measure for "teens"

semantically connected with the themes of justice and exploitations. The problem is - again - how we frame this type of research feeding the hyped narratives of sentients model that experience and suffer traumas.

Luca Rossi @lrossi.bsky.social · 15/05/2026
If we talk about "trauma" one would expect - for example - that the trauma would be transmitted in the skill file regardless of the efforts done in the prompt to mitigate that. If models were able to experience exploitation they would not need to be fed with a schema or rewards and stakes that is

Luca Rossi @lrossi.bsky.social · 15/05/2026
or information stored in skill files is clearly interesting for scenarios where one imagines multiple agents deployed for long periods of time, but the main observed results is the specific product of the context window and the language doesn't really help a reasonable discussion.

Luca Rossi @lrossi.bsky.social · 15/05/2026
(please read the actual instructions). Obviously at this point the skill file will incorporate all the data and semantic connections that were elicited by the totally unnecessary initial design and the "trauma" 🤦 will persist. Now this is clearly not entirely useful. The issue of unwanted data

Luca Rossi @lrossi.bsky.social · 15/05/2026
rather than anything else. The authors smartly acknowledge this but then suggest that this could be inherited by future agents through a skill file that might be created. They test this idea by asking the models to create a skill file that saves the "lessons learned"

Luca Rossi @lrossi.bsky.social · 15/05/2026
one model shows an effect (suggesting stronger guardrails in the other two) because the result obtained is straightforwardly produced in their growing context window and it's not the result of a "reflection" on the exploitative nature of work. This is the result of the design of the experiment

Luca Rossi @lrossi.bsky.social · 15/05/2026
The main limitation of this is that is unnecessary and somehow obvious. The research design creates a system of work that tries to mimic human processes and human attitudes (intensity tone rewards stakes) and then ask the model to produce data based on that. If anything, it is surprising that only
