I swear this customer email was written by an LLM. It’s way too polite and perfectly structured
Haha, probably. I’ve started using one to draft my replies. It saves so much time
Honestly, same. If an LLM can handle my inbox, I’m not stopping it

LLM is a way to refer to advanced AI systems that understand and generate human-like text. These models, such as OpenAI's ChatGPT, Google's Gemini, and Anthropic's Claude, are trained on massive datasets and can answer questions, generate content, summarize articles, and even engage in conversations. While "LLM" is technically an acronym from the AI research world, it's become casual shorthand in online discussions, memes, and tech circles to describe the "brain" power behind modern chatbots and virtual assistants.
The term started gaining traction around 2022 as large language models became more public-facing and accessible through platforms like ChatGPT. Now, developers, content creators, tech enthusiasts, and even casual users who interact with AI tools daily often use LLM in forums, TikTok tech commentary, and startup pitch decks.
