What AI tools get wrong, where their limits are, and how to work around them.
AI vs machine learning, in plain English: AI is the broad field, machine learning is the part that learns patterns from data instead of following hand-written rules. Covers the difference, deep learning, and worked examples — spam filters and chess engines built both ways.
ChatGPT error generating a response: what 'There was an error generating a response' means and the fix ladder in OpenAI's own order — Regenerate first, then restart, VPN and security filters off, incognito or a different browser, a different network or device.
Claude and ChatGPT compared on the facts both companies publish themselves in November 2026: Claude Pro is $20 a month and ChatGPT Plus is $20 a month, Claude's current models carry a 1M-token context window in paid chat, and ChatGPT's edge is its wider ecosystem of image creation, voice, deep research and custom GPTs. A use-case verdict, not a fake winner.
Delete your ChatGPT account permanently, using OpenAI's own current steps: the web route through Settings and Account, the iPhone and Android routes through Data Controls, and the Privacy Portal route for when you cannot sign in — plus what gets deleted and what is retained, why you must cancel an Apple or Google Play subscription first, and what deletion does to your API access.
How to tell whether ChatGPT is down for everyone or the fault is yours to fix: OpenAI's official status page at status.openai.com, how to read its components and incident history, Downdetector as a secondary signal, the error messages that appear during real outages, and the own-side checks — browser, network, VPN, app — to run when the status page is green.
The fastest way to tell whether Claude is down for everyone or the problem is on your side: Anthropic's official status page at status.claude.com, what each component status means, how to read an incident timeline, Downdetector as a secondary signal, and the look-alike problems — usage limits, capacity messages and sign-in faults — that are not outages at all.
A large language model is a deep learning system trained on huge amounts of text to predict the next token, again and again — and that simple trick, done at enormous scale, is what lets it write, summarise, translate and answer. Plain-English guide to what LLM means, how LLMs work, tokens and parameters, examples, how an LLM differs from AI itself, and what LLMs cannot do.
An AI hallucination is an answer from a chatbot or AI model that sounds confident and plausible but is false — an invented fact, a citation that does not exist, or a detail that contradicts the source. Why it happens, the main types, the real-world risks, and how to spot and reduce hallucinations.
Generative AI is artificial intelligence that creates new content — text, images, code, audio and video — instead of only analysing or classifying what already exists. Plain-English guide to the meaning, how it works through foundation models, concrete examples for each content type, how generative AI differs from traditional and discriminative AI, and its real uses and limits.
ChatGPT's file upload limits checked against OpenAI's own help center in November 2026: 3 files a day on Free, up to 80 files every 3 hours on paid plans, 512 MB per file, and the two different storage caps most guides mix up.
