xAI launches Grok Build Marketplace, integrates real-time sentiment for eToro's Tori

xAI has launched the Grok Build Plugin Marketplace, opening its Grok AI ecosystem to third-party developers. The marketplace allows creators to build and distribute plugins that extend Grok's capabilities across reasoning, code generation, voice, images, and video. This move transforms Grok from a standalone chatbot into a platform, leveraging the same Grok-4.3 model family that powers 300 million queries per day with a median latency under 200 milliseconds. The unified API supports Python, TypeScript, and cURL, making it accessible for rapid integration. xAI also revealed that 150K GPUs are now deployed in its Colossus supercluster, underscoring the massive compute backing these new offerings.

In parallel, xAI integrated real-time market sentiment data into Tori, the social trading platform from eToro. This feature delivers live sentiment analysis on stocks and crypto directly within Grok's interface, giving traders actionable insights without switching contexts. The integration is part of a broader push to embed Grok into real-world applications, following similar partnerships with Gopuff (powering their Go agent) and the release of Grok Imagine 1.5 Preview for multimodal generation. With the plugin marketplace and eToro integration, xAI is positioning Grok as both a developer platform and a practical tool for financial professionals.
