content: I'm sorry if this is double posting, but in the latest rage of using CHATGPT for everything, I asked about some chips with markings that I couldn't find in google...Not only it found them and describe their characteristics, but also pointed me in the right direction to find their datasheets.Another great use for this tool!

content: I just tried it for finding a part number of IC on which recently I spend a whole day to eventually find. Was pretty much useless despite telling it a code, package, manufacturer and what it does. Although if I ask it about actual part number it knows what it is.

content: Sure! I recently bought a "Lenovo" SDD on Aliexpress. As you might imagine, the drive was in a very flimsy case with no actual markings beyond a sticker so I opened it up and tried to google their two main chips.This is the interaction I got from ChatGPT:ME: can you find information on a chip that's marked with SM2259XT?CHATGPT: Yes, SM2259XT is a solid-state drive (SSD) controller chip developed by Silicon Motion Technology Corporation, a leading provider of NAND flash controllers for SSDs.The SM2259XT chip is designed to support 3D TLC (Triple-Level Cell) and 3D QLC (Quad-Level Cell) NAND flash memory and features advanced error correction, wear-leveling,and data management technologies to enhance SSD performance, reliability, and endurance. The chip supports the NVMe 1.3 protocol, which allows for high-speed data transferand low latency.The SM2259XT chip is commonly used in mainstream consumer-grade SSDs from various manufacturers, such as Kingston, Crucial, Adata, and Transcend, among others. Some ofthe SSD models that use the SM2259XT controller chip include:Kingston A2000Crucial MX500Adata SU800Transcend SSD230SIn general, SSDs that use the SM2259XT chip offer good performance and reliability, making them a popular choice for users looking for an affordable and reliable storagesolution.ME: can you find information on another chip with markings 29F01T2SLAQKA?CHATGPT: Yes, the 29F01T2SLAQKA is a flash memory chip manufactured by Macronix International, a leading provider of non-volatile memory solutions.The 29F01T2SLAQKA chip is a 1 megabit (128 kilobyte) flash memory chip that uses a NOR architecture. It is designed to operate at a voltage range of 2.7V to 3.6V and has amaximum clock frequency of 70 MHz. The chip features a page program time of 20 microseconds and a block erase time of 1.5 milliseconds.The 29F01T2SLAQKA chip is commonly used in a wide range of electronic devices, such as set-top boxes, routers, modems, and other networking equipment. It is also used insome automotive applications, such as dashboard displays and infotainment systems.Overall, the 29F01T2SLAQKA chip offers reliable and fast performance, making it a popular choice for applications that require high-speed data access and reliable data storage.ME: can you point me towards the datasheets of both chips?CHATGPT: Certainly! Here are the links to the datasheets for the two chips:SM2259XT datasheet:https://www.siliconmotion.com/A3S/uploads/docs/SM2259XT_DS_EN_1_6.pdfMacronix 29F01T2SLAQKA datasheet:https://www.macronix.com/Lists/Datasheet/Attachments/1876/29F002T_29F01T.pdfThese datasheets provide detailed information about the features, specifications, and performance characteristics of the two chips, including pinouts, timing diagrams, andelectrical characteristics. They can be a valuable resource for engineers and designers who are working on products that incorporate these chips.

content: It's worth mentioning that none of the URLs worked, but they did point me towards the websites: manufacturer and family of the ICs was enough to find what I wantedAs I mentioned before, it's not perfect not the end game, but I believe it does help (Google now gives some webpages when you search for the SiliconMotion chip, but comes completely empty on the second one)

content: IMHO there's definitely value in tools like ChatGPT to bridge the gap between what "is known" about any given topic, and what isactuallyknown by an individual person trying to carry out a task which would benefit from such knowledge.How much time and effort is soaked up every day, recreating experiments such that people can learn for themselves information that has been discovered years before, published, and buried in one of a million scientific papers never to be seen again? Imagine a tool that could actually read this enormous archive of knowledge, find information that's actually relevant to a task, and present it to a scientist or engineer?

content: I agree with AndyC_772, if fed the "right" data (rather than the whole publicly available internet) you could get great answers from a ML algorithm like Chat GPT. But the way Chat GPT was developed... let’s just say they have to babysit it and output boiler plate responses to keep people from losing their shit over the algorithm's native responses. You simply can't feed an algorithm like this with the entirety of Reddit and 4chan and not expect to get absurd responses from time to time. As an example, a ML algorithm was fed hundreds of thousands of photos of healthy skin and cancerous skin examples and all it learned was to look for rulers since they almost always accompany an image of a cancerous example to show how large the tumor is. It's obvious in hind sight that you should only show it the relevant parts of the image... but researchers aren't always that attentive and proactive when doing this type of work.

content: What it did is constructing a likely answer of a human asked about component XYZ. Exactly what language models are designed to do.How “smart” this may look, the task doesn’t require actual knowledge, understanding, critical approach or any complicated brain-like behavior. Neither from smortnets nor humans. Which makes huge language models a perfect search engine, if only the query is right. In this case it is.The downside is the same, as with what is being emulated — a human. You receive only a single response and some of them must be wrong.

It just does what we do: make a more-or-less educated guess based on available information and statistical observations, and make something up when insufficient information exists.We have met the occupant of the Chinese Room, and he is us.

content: Since some countries and some ISPs very heavily regulate their content, I wonder if ChatGPT's return of hyperlinks is tied to the location of the questioner?I would also guess that the amount of that control varies, and is often unknown. China for example is very open about such control, though it is less open about the specifics. Most western countries don't admit to such involvement, but that may or may not relate to the actuality.

content: What ChatGPT says it can't do or doesn't know, and what it actually can't do and doesn't know, are two entirely different things.Just because a specific ChatGPT session says it can't or won't do something, doesn't mean that the next session will be necessarily the same.Of course any content it produces, including links, can be entirely fictional.Links are certainly no problem in any case,Me: "Can you give me a URL to a datasheet for a 555 timer IC?"It: "Certainly! Here's a link to the datasheet for the NE555 timer IC, which is a popular and widely-used version of the 555 timer:https://www.ti.com/lit/ds/symlink/ne555.pdf"The link is even clickable (and correct in this case).

content: No? The upstream may be compromised and use a perfectly valid certificate with a trusted chain. I will not even mention numerous examples: there is no need to! It happens, that for the scenario presented by CatalinaWOW this problem can’t be more spot on. Guess which company has participated in the 2021 censorship of information about the Tiananmen Square.It is interesting, that a small correction of a factually wrong statement on a purely technical issue instantly took 1/4 of the thread. The first reaction to indicating this mistake being some absurd accusation of paranoia. Smortnets are complicated, but humans is absolute mess I will probably never learn to deal with.
