CalyxAI, a startup building multimodal reasoning models, closed a $120 million Series B led by Horizon Ventures with participation from several strategic cloud partners. The company plans to use the funds to expand R&D, scale inference infrastructure, and onboard enterprise customers in finance and life sciences.

The firm’s flagship product, Calyx Reasoner, combines visual understanding, document parsing, and time-series analysis in a unified API. Calyx says the latest model improves cross-modal coherence and reduces hallucination in complex queries by 30% relative to their previous release.

Investors pointed to rising demand for AI systems that can synthesize diverse data types for compliance, research, and decision support. Calyx expects to launch a managed cloud offering later this year and expand its partnerships with analytics vendors and EHR providers.
