Hi everyone!

The most impressive thing about the Grok Code Fast 1 launch is its wide availability from day one. It's already integrated into many of the most popular agentic coding platforms, including @Github Copilot @Cursor @Cline @opencode and so on.

The model itself is built from scratch to be a speedy and economical daily driver for agentic coding, striking a great balance between performance and cost.

To help you get the best results, xAI has also prepared a Prompt Engineering Guide for this model.

Just came across it, love that it's free right now. I've been curious about trying new AI models for coding and this seems like a great way to test speed versus accuracy.

Congrats on the launch! The focus on agentic coding is super timely

Wishing you all the best with adoption!

Interesting that it focuses on speed and affordability. I've been using Copilot for months but I'll definitely try this out. If it saves time while being economical, that's huge.

I really appreciate that it is available on multiple platforms. Having it on GitHub Copilot and Cursor means I don't need to change my workflow much to explore its benefits.

I like that it emphasizes agentic coding. It feels like tools are evolving from just suggesting code to actually helping reason through problems, which could really change my development process.

The fact it is free for a limited time makes me want to test it right away. No better chance to see how it handles compared to Copilot on real projects.

Congrats! Still testing… Honestly, it's too fast for me to read the CoT and to be able to clarify something if the model makes a wrong assumption. It's not a vibe coding model, it needs a lot of specific instructions to be useful. Also, it likes to be very verbose with its solutions and overcomplicates code. In my testing it's honestly not that special apart from the speed.

So it’s free on Copilot and Cursor? 🤔 Curious how it stack vs Claude Sonnet on real-world repo scale.
