TL;DR

Grok 4.5 has launched, and aims to better handle complex coding, spreadsheets, and presentations.

The new model can build apps, generate advanced Excel workbooks, and create PowerPoint and Word documents from a single workflow.

SpaceXAI says Grok 4.5 is faster, more token-efficient, and cheaper to run, with API pricing starting at $2/$6 per million input/output tokens.

It feels like there’s a new AI model every other day, but Grok 4.5 isn’t just another chatbot update. This time, the focus is on helping you get more done with fewer prompts.

If you’ve ever asked an AI to write some code, create a spreadsheet, or put together a presentation, you probably know the drill — the first draft is rarely enough. You tweak your prompt, ask it to fix mistakes and add missing details, and repeat the process until you finally get what you want. Grok 4.5 aims to reduce that extra work by handling more complex requests in one go. For X subscribers who use Grok regularly, this could be one of the more meaningful upgrades yet.
