Welcome to AI Unraveled, the podcast that demystifies frequently asked questions on artificial intelligence and keeps you up to date with the latest AI trends. Join us as we delve into groundbreaking research, innovative applications, and emerging technologies that are pushing the boundaries of AI. From the latest trends in ChatGPT and the recent merger of Google Brain and DeepMind, to the exciting developments in generative AI, we’ve got you covered with a comprehensive update on the ever-evolving AI landscape. In today’s episode, we’ll cover GPTs and LLMs, their pre-training and fine-tuning methods, their context window and lack of long-term memory, architectures that query databases, PDF app’s use of near-realtime fine-tuning, and the book “AI Unraveled” which answers FAQs about AI.

GPTs, or Generative Pre-trained Transformers, work by being trained on a large amount of text data and then using that training to generate output based on input. So, when you give a GPT a specific input, it will produce the best matching output based on its training.

The way GPTs do this is by processing the input token by token, without actually understanding the entire output. It simply recognizes that certain tokens are often followed by certain other tokens based on its training. This knowledge is gained during the training process, where the language model (LLM) is fed a large number of embeddings, which can be thought of as its “knowledge.”

After the training stage, a LLM can be fine-tuned to improve its accuracy for a particular domain. This is done by providing it with domain-specific labeled data and modifying its parameters to match the desired accuracy on that data.

Now, let’s talk about “memory” in these models. LLMs do not have a long-term memory in the same way humans do. If you were to tell an LLM that you have a 6-year-old son, it wouldn’t retain that information like a human would. However, these models can still answer related follow-up questions in a conversation.

For example, if you ask the model to tell you a story and then ask it to make the story shorter, it can generate a shorter version of the story. This is possible because the previous Q&A is passed along in the context window of the conversation. The context window keeps track of the conversation history, allowing the model to maintain some context and generate appropriate responses.

As the conversation continues, the context window and the number of tokens required will keep growing. This can become a challenge, as there are limitations on the maximum length of input that the model can handle. If a conversation becomes too long, the model may start truncating or forgetting earlier parts of the conversation.

Regarding architectures and databases, there are some models that may query a database before providing an answer. For example, a model could be designed to run a database query like “select * from user_history” to retrieve relevant information before generating a response. This is one way vector databases can be used in the context of these models.

There are also architectures where the model undergoes near-realtime fine-tuning when a chat begins. This means that the model is fine-tuned on specific data related to the chat session itself, which helps it generate more context-aware responses. This is similar to how “speak with your PDF” apps work, where the model is trained on specific PDF content to provide relevant responses.

In summary, GPTs and LLMs work by being pre-trained on a large amount of text data and then using that training to generate output based on input. They do this token by token, without truly understanding the complete output. LLMs can be fine-tuned to improve accuracy for specific domains by providing them with domain-specific labeled data. While LLMs don’t have long-term memory like humans, they can still generate responses in a conversation by using the context window to keep track of the conversation history. Some architectures may query databases before generating responses, and others may undergo near-realtime fine-tuning to provide more context-aware answers.

GPTs and Large Language Models (LLMs) are fascinating tools that have revolutionized natural language processing. It seems like you have a good grasp of how these models function, but I’ll take a moment to provide some clarification and expand on a few points for a more comprehensive understanding.

When it comes to GPTs and LLMs, pre-training and token prediction play a crucial role. During the pre-training phase, these models are exposed to massive amounts of text data. This helps them learn to predict the next token (word or part of a word) in a sequence based on the statistical likelihood of that token following the given context. It’s important to note that while the model can recognize patterns in language use, it doesn’t truly “understand” the text in a human sense.

During the training process, the model becomes familiar with these large datasets and learns embeddings. Embeddings are representations of tokens in a high-dimensional space, and they capture relationships and context around each token. These embeddings allow the model to generate coherent and contextually appropriate responses.

However, pre-training is just the beginning. Fine-tuning is a subsequent step that tailors the model to specific domains or tasks. It involves training the model further on a smaller, domain-specific dataset. This process adjusts the model’s parameters, enabling it to generate responses that are more relevant to the specialized domain.

Now, let’s discuss memory and the context window. LLMs like GPT do not possess long-term memory in the same way humans do. Instead, they operate within what we call a context window. The context window determines the amount of text (measured in tokens) that the model can consider when making predictions. It provides the model with a form of “short-term memory.”

For follow-up questions, the model relies on this context window. So, when you ask a follow-up question, the model factors in the previous interaction (the original story and the request to shorten it) within its context window. It then generates a response based on that context. However, it’s crucial to note that the context window has a fixed size, which means it can only hold a certain number of tokens. If the conversation exceeds this limit, the oldest tokens are discarded, and the model loses track of that part of the dialogue.

It’s also worth mentioning that there is no real-time fine-tuning happening with each interaction. The model responds based on its pre-training and any fine-tuning that occurred prior to its deployment. This means that the model does not learn or adapt during real-time conversation but rather relies on the knowledge it has gained from pre-training and fine-tuning.

While standard LLMs like GPT do not typically utilize external memory systems or databases, some advanced models and applications may incorporate these features. External memory systems can store information beyond the limits of the context window. However, it’s important to understand that these features are not inherent to the base LLM architecture like GPT. In some systems, vector databases might be used to enhance the retrieval of relevant information based on queries, but this is separate from the internal processing of the LLM.

In relation to the “speak with your PDF” applications you mentioned, they generally employ a combination of text extraction and LLMs. The purpose is to interpret and respond to queries about the content of a PDF. These applications do not engage in real-time fine-tuning, but instead use the existing capabilities of the model to interpret and interact with the newly extracted text.

To summarize, LLMs like GPT operate within a context window and utilize patterns learned during pre-training and fine-tuning to generate responses. They do not possess long-term memory or real-time learning capabilities during interactions, but they can handle follow-up questions within the confines of their context window. It’s important to remember that while some advanced implementations might leverage external memory or databases, these features are not inherently built into the foundational architecture of the standard LLM.

  Too Late to start with AI? (deep dive/discussion, do contribute!)
  by /u/CanFluid (Artificial Intelligence) on February 16, 2026 at 3:52 pm

  Background : Software Engineer at an MNC with work only related to backend tech stack predominantly java Spring boot, our org is shifting towards cloud infra (yeah a lot of legacy debt). Trigger to start AI: Read this post the other day on how the AI is changing the software Engineering landscape and how fast its progressing. The models which used to hallicunate are making learned decisions make it clear that "something big is happening" (also the title of the article i read). But i knew all of this, why get triggered now? i was largely cut off by the ecosystem by only focusing on what i had on my plate, my work at the company and having some time for myself to not get a burn out.. Curious enough on a weekend i started pondering on clawd bot , agentic AI systems and ofc claude opus 4.6 .. and what came next blew my mind.. I was able to ship an end-to-end working application from frontend to backend with databases and a free cloud provider IN A WEEKEND!! (tbh, if i had an unlimited token count i believe it would've taken a few hours at max!) the ability of a model to write code and handle test , make pipeline and deploy is scary! openAI stated it fine tuned and developed its newest codex model 5.3 with its own model, so in a wild sense.. models are making their own models and getting tuned(learning along the way) and if you make a point of it being a machine that only needs energy and infra, it will run 24/7 round the clock towards achieving its goal! the fact that i was going to ask AI to write this article for me was comical on its own(i chose not to so, you can make that jusdgement looking at my grammar and punctuations and a OCD to use parenethesis , idk why.. so trust me i wrote it) A lot of people say if you are going for a PhD today, its going to be absolutely worthless because these LLM's are far more efficient in getting us the results in record time, and the same guys tell us to upskill to not get left behind? I mean, WHAT SHOULD I DO BRO? TELL ME?? at times i feel like we are at mercy of the top brass, they'll be building models we would be the worker class, or may be in future donating our bodies to them to store data/produce energy? (matrix reference) What i'll be doing: I think i'll anyway be starting with some basics of AI and gradually building on top, idk what the future holds but i can't just sit like this knowing what's been brewing Request: I'd humbly request for a guidance, or a mentor(i never had one) or anything you think would add value towards my preparedness.. I also urge you guys to have a healthy discussion on the comment section on your thoughts and share it for the greater good! [Marking this post as a checkpoint on what i'll achieve in next 1 year or anyone who'll be starting with me on this journey.] submitted by /u/CanFluid [link] [comments]

  Suggestions: Chatgpt plus to what?
  by /u/AdLongjumping4144 (Artificial Intelligence) on February 16, 2026 at 3:44 pm

  I've been using chatgpt plus plan for nearly a year now. Mostly for daily tasks. I usually don't code but even when I do. I also have gemini pro plan so I use antigravity. I only use it for daily tasks and paying 20 dollars for that is really unnecessary. I'm thinking of changing it to another ai service. For daily usage, storywriting, and sometimes code writing. I don't need limits to be extremely high but It should at least be over daily usage. I can pay maximum 30-40 dollars a month submitted by /u/AdLongjumping4144 [link] [comments]

  Are AI note taking apps overhyped right now?
  by /u/adriano26 (Artificial Intelligence (AI)) on February 16, 2026 at 2:36 pm

  Every few weeks there’s a new “best AI note taking app” claiming to fix meetings forever. In reality, most of them summarize decently, but once conversations get long or chaotic, things fall apart. I’ve used Bluedot mostly to avoid typing during meetings, and it helps, but I still review everything. Are we just in the early hype phase for AI note taking apps, or is this as good as it gets with current models? submitted by /u/adriano26 [link] [comments]

  OpenAI hired the OpenClaw creator. The military used Claude in the Venezuela raid. The Pentagon may drop Anthropic's $200M contract. Disney accused ByteDance of an IP 'smash-and-grab.' (15 Feb 2026 recap)
  by /u/fabioperez (Artificial Intelligence) on February 16, 2026 at 2:21 pm

  Here are the most important news from the past two days: OpenAI hires OpenClaw creator Peter Steinberger to build 'next-generation' AI agents OpenAI hired Peter Steinberger, creator of the viral AI agent OpenClaw, to lead development of next-generation personal agents. Sam Altman called him "a genius" and said multi-agent capabilities will "quickly become core to our product offerings." OpenClaw will move to an independent foundation while remaining open source with OpenAI support. Steinberger chose OpenAI over starting a company, saying "what I want is to change the world, not build a large company." His goal: an agent "even my mum can use." The hire comes with baggage: security researchers found thousands of exposed OpenClaw instances vulnerable to remote code execution and dozens of malicious skills on its marketplace containing keyloggers and credential stealers. (read the full story) US military used Anthropic's Claude in the operation to capture Venezuela's Maduro The Pentagon deployed Claude during the January 3rd raid on Nicolás Maduro's fortified palace in Caracas, through Anthropic's partnership with Palantir. Delta Force commandos used the AI during the active operation—not just in planning. People were shot during the breach. An Anthropic executive reached out to Palantir afterward to ask whether Claude had been used, "in a way to imply that they might disapprove of their software being used, because obviously there was kinetic fire during that raid." Claude was the first AI model the Pentagon brought into its classified networks. The revelation has intensified a growing rift between the "safety-first" AI lab and its biggest government client. (source) Pentagon threatens to drop Anthropic's $200M contract over military AI limits The Pentagon is considering severing its relationship with Anthropic because the company won't remove all restrictions on military use of Claude. The Defense Department is pushing four AI labs—OpenAI, Google, xAI, and Anthropic—to allow "all lawful purposes," including weapons development and intelligence collection. OpenAI, Google, and xAI agreed to lift their guardrails. Anthropic refused. Anthropic insists two areas remain off limits: mass surveillance of Americans and fully autonomous weapons. The contract, signed last summer, is valued up to $200M. Internally, Anthropic engineers are uneasy about Pentagon work. The standoff puts the company's safety brand directly against its biggest government revenue stream. (source) ByteDance pledges Seedance 2.0 safeguards after Disney cease-and-desist ByteDance said it will strengthen safeguards on its video generation tool Seedance 2.0 after Disney and Paramount sent cease-and-desist letters. Disney accused ByteDance of a "virtual smash-and-grab" of its IP, claiming the model ships with "a pirated library" of Star Wars and Marvel characters. The Motion Picture Association and SAG-AFTRA also condemned the tool. Disney's response reveals selective enforcement: it sued ByteDance but struck a deal when OpenAI's Sora produced similar content. The difference? Geopolitics. Chinese-owned ByteDance gets the lawsuit; American OpenAI gets a licensing agreement. (source) Other important stories A global DRAM shortage is hammering tech profits. Musk, Cook, and others warn AI data centers consume an increasing share of memory chip production. SemiAnalysis called it the worst shortage in 40 years. (source) UK PM Starmer will require AI chatbots to comply with the Online Safety Act or face bans, following the Grok scandal where Musk's AI generated sexualized images of real people. (source) NPR host David Greene is suing Google, alleging NotebookLM's male podcast voice is based on him. Google says it's a paid actor. (source) Computer science enrollment fell 6% across the UC system—the first decline in 20 years—as students pivot to AI-specific degrees. (source) Stanford economist Erik Brynjolfsson says the AI productivity liftoff has begun—US productivity jumped 2.7% in 2025, nearly double the decade average.
