Grok now lets you drop 100 files into one chat

Grok just unlocked a genuinely useful power-user feature: you can now attach up to 100 files — PDFs, images, documents — in a single session and query across all of them at once.

File context persists across conversation turns, so you can do multi-step analysis: upload 50 contracts, ask for red flags, then drill down. For researchers, analysts, or anyone drowning in docs, that's a meaningful workflow upgrade.

xAI also quietly raised the max file size to 1 GB (up from 512 MB), and files are processed in-memory only — not stored after the session ends.

Why it matters: most AI chat interfaces still feel like single-file workflows. Grok is quietly positioning itself as a serious document analysis tool, not just a chatbot.
