Cool, but it's still unusable for me. Somehow all my prompts are violating the rules, huh?

In 25 years we'll reminisce on the times when we could find a human artist who wouldn't impose Google's or OpenAI's rules on their output.

the open-source models will catch up, 100%

Open models don't seem to be catching up the LLM-based image gen at this point.

ChatGPT's imagegen has been released for half a year but there isn't anything remotely similar to it in the open weight realm.

Give it another 50 years. Or maybe 10. Or 5? But there's no way it won't catch up.

Are you asking it to recreate people?

No, and no nudity, no reference images. Example: 'athlete wearing a health tracker under a fitted training top'

Can you give us an example?

'athlete wearing a health tracker under a fitted training top'

It's not the censorship safeguard. Permission denied means you need a paid API key to use it. It's confusing, I know.

If you triggered the safeguard it'll give you the typical "sorry, I can't..." LLM response.

Have some examples?

Congrats guys on your release. I tried new VitalLens side by side with my medical grade tracker (Aidmed One) but the respiration numbers were quite off.

Curious if you've done any comparisons against actual hardware (chest-based or contact PPG), or if validation is mostly dataset based for now.

Thanks! Curious under what circumstances the respiration was off - were you standing or sitting down? I can usually see the resp wave go up and down as I breathe while sitting down.

I have written up a technical report on the validation here: https://arxiv.org/abs/2510.27028 This validation is based on several datasets, which all have gold standard ground truth from contact PPG and RESP from chest straps and/or impedance pneumography (from ECG)

> It's not sexy, and as a result an overwhelming majority of the population is unaware about how to avoid succumbing to it

When I started building an ECG Holter in my early 20s, I tried to get some friends to use it and kept hearing "yeah, but it’s not exactly sexy to wear that thing." That’s when it hit me how little people care about prevention until something goes wrong. We still have a huge awareness gap to close.

I asked a heart doctor for a calcium scan. He said I didn't need that, but he wanted me to wear a Holter monitor for a few days (reasons unknown). I did not.

That was years ago. I have different doctors now but still no calcium scan. Time to ask again possibly.

So I went on X after a long break from social media, and my feed is full of tips like this one:

Growing on X is so simple I’m shocked it works.

100x comments a day

10x posts a day

15x DM’s a day

1x thread a day

1x email a day

This is how you grow your presence on X.

Even if having a presence matters, how can you actually say something meaningful if you post 10 times a day - there's no way (unless you just repeat yourself). Hopefully my algorithm's just gone weird but sadly the people I used to follow stopped posting.

Hey, can you join our Discord: https://discord.gg/sPay3Xm? Reach out to me personally (@guzik1) - happy to help you with that as we've already had a few people who integrated with rpi, so I can share some tips and examples.

Thank you! We've integrated a different chip for measuring chest movements

sadly, comfort for chest straps compared to hand straps is a known issue and ours is definitely no different. Wve done a bunch of tests, tried different materials/custom solutions, and honestly we're still clueless how to make it significantly better (if anyone here works in textiles or wearable fabrics, I'd love to connect). So yeah, if wearing your Garmin for more than an hour already feels uncomfortable, ours probably won't be much better in that regard

for regular users, since the device itself doesn't have any interface, we need to send at least some data so they can see it somewhere. the natural place is the phone, but not all of our professional clients liked viewing long ECG recordings or detailed metrics on a small screen, so we built cloud access mostly for convenience .

(to be clear - if a developer wants, they don't need to send anything to us)

Thanks! Yep, the interface for a shell is available here: aidlab.com/developer/debug we are using Jquery Terminal + Web Bluetooth (sadly, I think it's not under active development anymore)

and yeah, when we started years ago, it felt natural that the next step would be to measure glucose from blood but the truth is with the current state of science, it's still not possible to do that 100% non-invasively.
