Excited to see xAI officially launch the Grok 3 API!


Grok has always aimed to be a bold, unfiltered alternative in the AI space, and now developers can tap into its reasoning capabilities and multimodal power through an API.


Whether you're building smart assistants, creative tools, or research agents — Grok 3 and Grok 3 Mini offer flexibility with different performance tiers and pricing.


What stands out is its unique personality and willingness to push boundaries that other models often avoid. While it’s still catching up in some benchmark areas, Grok’s distinct voice and Musk’s vision behind xAI make this a fascinating launch for builders looking to explore something new.


Can’t wait to see what the community creates with it!

Excited to see Grok 3 opening up—131K context is no joke. How does it handle long-form reasoning compared to GPT-4 or Claude 3 in your early tests?

Offering both Grok 3 and Grok 3 Mini definitely adds a lot of flexibility for devs.
