Main announcement · Blog Now that Grok 4.5 is available, we’d love to hear how it’s working for you. Some things we’re especially curious about: What are you using it for beyond coding? This is the first model we’ve built for more than software engineering. If you’ve pointed it at data science…

Is it using Auto/Composer usage or API usage? And wow it’s so fast even in non-fast and incredibly cheap..

My API usage jumps from 21% to 22% while using Grok 4.5, so it clearly costs API usage.
