xAI's API for Grok models, with text, image and video generation, voice, and built-in web and X search tools.
Works with AI agents:llms.txtBuilt into v01 tools, from its own code, website and Product Hunt page.
6 makers' products, each linked to the source that shows it, and 33 open-source projects that declare it in their code.
IFTTTEvery thing works better together“Grok pairs real-time knowledge with strong reasoning in a way that makes it genuinely useful for live, in-the-moment automations. We chose it because it doesn't just know a lot, it knows what's happening right now.”

What makes it stand out is its creative problem-solving approach that often generates novel workflow solutions beyond what users might have initially imagined, leading to more efficient automations.”

ChinillaDesign systems, simulate them and watch where they break“Best cost-to-quality ratio for structured JSON generation. Chinilla needs every AI response in strict JSON (components, connections, behaviors) and Grok handles that reliably at a fraction of the cost per token. When you're burning hundreds of AI calls per user session on system design, code mapping, and simulation analysis, the pricing difference adds up fast.”
