What “Hallucination” Actually Means in AI (and Why the Word Is Misleading)

AI systems can write articles, summarize documents, generate code, and answer complicated questions in seconds. But they also make mistakes. Sometimes those mistakes are small, like getting a date wrong. Sometimes they are serious, like inventing a fake research paper, a non-existent feature, or a source that never existed. The AI community usually calls this … Read more

What Temperature Actually Does to AI Output (and Why 0.7 Is Not Always Better)

When people use AI tools like ChatGPT, Claude, or Gemini, they often assume the model simply answers based on what it knows. Behind every response are settings that influence how the model generates text. One of the most misunderstood settings is temperature. Temperature controls how predictable or varied an AI response can be. A lower … Read more

What Tokens Mean in AI Billing (and Why 1,000 Tokens ≠ 1,000 Words)

Article Body Artificial intelligence companies rarely charge you by the word. Instead, they charge by tokens. If you’ve looked at the pricing pages for ChatGPT, Claude, Gemini, or AI APIs, you’ve probably seen phrases like input tokens, output tokens, or cost per million tokens. Tokens are simply the small chunks of text an AI model … Read more
