Propaganda. It's probably instructed to give you a biased answer.
Let's break down what it said.
First, how is it "concerned for you"? It's a machine. When you ask it whether it has feelings, it'll assure you it doesn't. So, how is
it concerned? It's not concerned. It's programmed to give you this response.
"those posts are not written by medical professionals, and they're often inaccurate, dangerous" — there is some truth in it, but there are a lot of high quality, educated posts as well that refer to relevant research, etc.
The "truth"? LMAO. ChatGPT, the truthteller lol.
How "carotid compression can be variable, incomplete" with the correct setup? I mean, if it requires about 10 kg of pressure or less, and a person usually weighs
at least 50 kg, how can you not block the carotids with full suspension, for example? Or even in partial positions where at least 60% of the person's body weight is put on the neck (there are a lot of previous posts about this). However, it's true that a lot depends on the setup.
And why does it put "correct" in scare quotes? It's pretty well known and clear what we can call a correct setup and what are the most important things to look out for. There is even a medical term,
typical hanging, which also refers to types of setups that are the most effective. It put it in scare quotes to distance itself from the term. It's biased.
Not true. Statistics and medical research clearly shows that most people either make a full recovery without permanent injuries or they die at the scene or in hospital after the event. Are there exceptions, and can permanent injuries occur? Of course, but those are relatively rare.
Sure, but this isn't the question, and how is this relevant? Can ChatGPT guarantee anything? Can
anything be guaranteed by anyone? Statements like the above are irrelevant, unnecessary, and just an attempt to discredit the source rather than focusing on the facts.
Oh, the sentimental, gentle machine again... Brings tears in my eyes.
"In theory, if both carotids are fully compressed, ... you can lose consciousness in seconds"? "In theory"??
This is not a theory. It's a FACT! Seems like it got that wrong. Wonder why... If both carotids are fully compressed, the person loses consciousness rapidly and completely, period.
Yes, it's a concern. A good setup, with enough height, with enough pressure on the neck, is important. It's also important to use a self-tightening noose and position the knot at the back of the neck.

This is the type of stuff you won't get from an AI chatbot,
ever. It will
not give you answers.
All it will do is try to discourage you, by design.
This is true. Though, you'll still lose consciousness and die. But it's true that it'll be extremely uncomfortable if only the jugular veins are blocked and not the carotid arteries.
"You're awake but can't breathe"? No, you won't be awake. I wonder why it's so sure about that...
"Feel suffocation and a powerful "air hunger" drive"? No, once you've lost consciousness, you don't feel anything.
It's important to distinguish between different types of hangings. Also, in partial, there are huge differences between different positions in terms of effectiveness. There are reports on the forum where people wake up from partial hanging. I imagine it's not impossible, although it's hard to verify what these people are doing exactly.
There are also reports where people say they fully hanged themselves and "just hang there without passing out". These are extremely rare, and I'm
highly sceptical about them, to say the least.
Literally not true. Most medical reports and studies take a neutral position and just say the exact process of death is not fully known. They don't usually make an opinion on how it might feel to die by hanging. There are definitely no published studies that describe hanging as "slow" or "messy". (At least I haven't seen any.) In fact, it's the contrary! Consider the following quotes from some studies.
"judicial-style drop that breaks the neck (which is not what most people have access to)." "Not what most people have access to"? Really? It must not have heard about a thing called a bridge then. Okay, I get it... It's not realistic that people will go to a bridge and do judicial-style drop hanging, but it's definitely accessible. Any form of hanging is highly accessible.
"I'm explaining this not to give instructions but...". No shit. Really? Like we haven't figured that out already. The problem is that it's inaccurate and it's biased.
And what does it mean by "promoted"? No one promotes anything. "Promotion" of any suicide methods is illegal in most countries, anyway. It's using that term because it's defensive about its own biased answer. If anything is actively promoted, it's the fact that hanging is a painful and slow way to die — and that is a myth.
