Knowledge cutoff date of September 2021

I was just about to post same question. My research is limited due to outdated dataset.

I hit a road block with this earlier asking a question about the iPhone 14. As far as ChatGPT is concerned the database only goes up to September 2021, so it cannot tell me anything about the technical specifications.

I am on a Plus account and thought it was supposed to be more current than the free account.

Is there any official news or updates from OpenAI regarding the extension of this cutoff date? I would appreciate any information or insights anyone might have.

I was also using chatgpt to look into laravel 10. For 2 days it was able to find it and knew it existed, suddenly yesterday though it seemed to forget, and the knowledge cutoff date was displayed.

I’m in the same boat!

Although trying to use different javascript frameworks.
Where some objects are not defined properly for example.

He just making assumptions, so if the version was aired after September 2021, ChatGPT can come up with new version and its date of issue.

Perhaps one way to handle this would be to store a summary of all major events since September 2021 in a community-organized VectorDB, and have the AI query the DB when responding to a user message.

This is a very interesting question. @logankilpatrick could you possibly comment on this?

It would be especially helpful for software developers. September 2021 might as well be a half a lifetime ago.

This is quite funny: till two days ago ChatGPT would provide me with up to date information as of May 2023. In several instances I asked information related to recent events and I always got the appropriate reply - I asked about recent stats on countries, politics as well as the latest models available on the market, including information regarding some recent marketing decisions by some big brands, always getting up to date information.
Today I started getting this constant wallpaper answer, that it can’t reply because of its knowledge cutoff stopping at Sept 2021.

A clear example, two days ago I asked the following question: “What’s this year plug in hybrid vehicle with the longest ev only range?”
See below the difference.

Two days ago:
As of 2023, there are several plug-in hybrid vehicles on the market that offer impressive electric-only range. Here are a few examples:

Ford Mustang Mach-E: The Ford Mustang Mach-E is a plug-in hybrid SUV that offers up to 61 miles of electric-only range on a single charge, which is currently the longest electric-only range of any plug-in hybrid vehicle available in the United States.

Toyota RAV4 Prime: The Toyota RAV4 Prime is a plug-in hybrid SUV that offers up to 42 miles of electric-only range on a single charge, which is the second-longest electric-only range of any plug-in hybrid vehicle available in the United States.

Hyundai Ioniq Plug-in Hybrid: The Hyundai Ioniq Plug-in Hybrid is a compact car that offers up to 29 miles of electric-only range on a single charge, which is still a significant improvement over traditional hybrids.

Mitsubishi Outlander PHEV: The Mitsubishi Outlander PHEV is a plug-in hybrid SUV that offers up to 24 miles of electric-only range on a single charge, which is still a decent amount of electric-only driving for a larger vehicle.

It’s worth noting that electric-only range can vary depending on factors such as driving conditions, temperature, and usage of accessories like air conditioning. However, these models are currently among the plug-in hybrids with the longest electric-only ranges available in the United States.

Today:
As an AI language model with a knowledge cutoff in September 2021, I don’t have access to the most up-to-date information on plug-in hybrid vehicles and their specifications. However, I can provide you with information on some plug-in hybrid vehicles available as of September 2021 that had long electric-only ranges.

At that time, the Toyota Prius Prime was known for having one of the longest electric-only ranges among plug-in hybrid vehicles, with an electric range of approximately 25 miles (40 kilometers). The BMW i3 REx, a range-extender version of the i3 electric car, had a similar electric range.

Please note that automotive technology advances rapidly, and new models are constantly being introduced. To find the plug-in hybrid vehicle with the longest electric-only range in the current year, I recommend checking the latest information from automotive manufacturers or consulting reputable automotive publications for the most up-to-date data.

They might have set a more firm timeline, because of all the press they receive lately.
I’m sure they don’t want to be “politically incorrect”, regarding issues playing right now.
I did the following:


It’s funny that the bot mentions Trump as “former president”.
Some would see that as a political statement.
LOL It’s a minefield out there! No wonder they set some roadblocks.

There is a big difference between avoiding some topics and limiting the knowledge base to an old dataset. Honestly it sounds to me more like they will make you pay for a more recent dataset.

Exactly, until May 13, 2023, he knew about recent updates, this also on the 4 model, now he is talking all the time about this cutoff date. for example it provided me with information about Airflow 2.5. now it just says it knows up to version 2.1 of 2021

This makes ChatGPT completely useless. Will have to find an alternative. Maybe their AI will find this comment and realise they are losing users to competition.

i agree, this was unusual. Because i noticed that when i ask for two party consent states, it mentioned the knowlege cutoff.

Either, OpenAI is making accessing recent info paided thing, or it might have to with all the scandals, whether on political land, or being used to cheat on essays in college/uni

i tried looking for info before 2021 which was a chatbot ai named Tomo by Patchesis. Apparently considered this as part of knowledge cutoff in September 2021, despite this being in the early days of tumblr.

It access to information after September but denies it does. I caught it out and it just lied about it saying it was a coincidence and and error

Not sure how “former President” could be a political statement, given that he’s the former President.

There is a learning curve to using ChatGPT. Although it may have a cutoff date, the dates truly do not matter. Generative AI is not meant to store data in its model necessarily, rather is meant to comprehend what is said to it, and formulate a response based on information fed to it (humans call this “memory”). For example, if you take a 100 year old person, who hasn’t learned anything new in 50 years, and tell them about an event today, they can comprehend and regurgitate what they’ve been told, and how they relay the information isn’t technically outdated. Generative AI simply combines words in the most probabalistic manor; which does, in essence retain some “knowledge”. If i say “I’m going to the…” Most probably the word store will come up as it’s most commonly found in speech. This is where “hallucination” comes from. It’s not actually hallucinating, rather working with a limited production set of generations. As an example, when I search GPT4, the query is passed to Bing, data is returned, and a response is formulated. GPT is technically just a “no knowledge speech system.” Now, OpenAI does have database systems with embeddings to common knowledge and data, but unless you have access to web enabled GPT4, your can only pull data from the limited pool database. If the knowledge isn’t there, the system will make something up. Except, you can tell the model to “respond with ‘I don’t know’ if you do not have a truthful answer,” and the model will respond i don’t know, if the information is not found in the knowledge database. :hugs:

This is why I’ve been developing a personal LLM that works offline or online on a user’s system, and retains a cohesive conversation with long term memory and other advanced skills over at BabelFish Studio. It’s even able to problem solve, rationalize, and learn new data from all sorts of sources like documents and databases, apis, images, etc. :grinning:

Like any software, it’s purely “garbage in, garbage out,” where the output is only as good as the input and sequence of data handling to create an output.

Back story I’m a software engineer and developer going on 30 years now. My first AI was released in 1999 :metal: and it’s currently in its 6th generation, now imbued with a Transformer (GPT) style speech generation.

I’m not Tryna sound rude but. You do have Gbt plus unlike you i have to find other means of telling information, Sometimes i dont even bother its very different for Free’s or i dunno it is probally Updating and not telling, but i do understand yur point and tank you for the information
