xAI's Grok 4.5 is drawing serious attention for its price-to-performance ratio, and this video tests it directly inside Cursor, the AI-powered code editor. The model handles knowledge work through a Canvas feature, generates landing pages from prompts, and builds functional apps including an Excalidraw clone backed by a Convex database.
The pricing segment at 2:58 is the section worth watching closely. The creator flags the cost as 'insane,' suggesting Grok 4.5 undercuts competitors at a meaningful margin. Combined with its design capabilities, tested in a dedicated Design Mode segment, the model is being positioned as a full-stack development tool, not just a code assistant.
The video closes with external validation, pulling in what other developers are saying about the model, which makes this more than a solo review. If the Convex integration and design output hold up under scrutiny, the Grok 4.5 plus Cursor pairing has a real case for replacing more expensive setups.
