Apple snuck a small LLM into macOS 27, accessible right from your Terminal as the command /usr/bin/fm. No Apple ID, no internet needed—just type fm and start chatting with the local “Apple Foundation Models” assistant. It’s not on par with GPT-5.5, but it runs smoothly on a stock M1 MacBook Air with 8 GB of RAM. Expect limited memory, occasional gibberish, and no awareness of current dates. Vemu spent a day running through ten practical use cases. He had fm draft emails, translate text between English and Japanese, summarize long Markdown files, and even generate regular expressions on demand. He used it to pull headlines from an RSS feed, format JSON responses, and turn CSV data into SQL insert statements. He also tested shell-command assistance—asking fm to build a find-and-replace script—plus simple math, like mortgage calculations. Beyond basic text work, Vemu pushed it further: journaling prompts, hex-color conversion for web design, and generating workout plans. He notes the model will hallucinate dates or invent functions if you push it too hard. Still, for quick drafts, format conversions, and lightweight coding help—especially when you’re offline—fm can save time without rattling your privacy.
