Versos AI Launches NVIDIA NeMo Agents for Video Training Data Curation

Versos AI, a provider of video training data infrastructure for library owners and AI labs, announced a new capability built with NVIDIA NeMo. This allows AI teams to describe their dataset needs in natural language, which the platform then uses to search, evaluate, and assemble rights-cleared video footage into structured training datasets. The workflow accelerates model development by reducing manual search and review time. It also enhances discoverability of premium video libraries for AI partnerships. The technology leverages NVIDIA CUDA for accelerated inference, NVIDIA Nemotron Ultra for agent reasoning, and LangChain for agent orchestration. Versos AI will demonstrate this at IBC2026 in Amsterdam.

• Versos AI launched a new capability built with NVIDIA NeMo.
• The system interprets natural language requests to find and assemble video training data.
• Built on NVIDIA CUDA Toolkit, NVIDIA Nemotron Ultra, and LangChain.

AI Productivity Boom Doesn't Reach Customers, Research Finds

The article examines a paradox in enterprise AI adoption: while individual productivity gains are real, customer-facing value and ROI remain flat. Research from WRITER shows 5x productivity gains but only 29% significant ROI, with 39% lacking revenue plans. Qualtrics finds AI-powered customer service fails at nearly 4x the rate of other AI uses, and TELUS Digital reports only 32% of enterprises use AI quality assurance tools. Accenture data reveals 86% plan to increase AI investment despite low impact. The article argues that companies succeed by redesigning processes around AI and measuring customer outcomes, not just internal speed. It highlights a growing distrust of AI in customer experience, with data misuse and blocked human access as key concerns, and calls for leadership accountability in proving customer value from AI investments.

• WRITER's 2026 survey (2,400 executives/employees) found individual AI users achieve ~5x productivity, yet only 29% of organizations see significant ROI.
• Qualtrics' 2026 research (20,000 consumers, 14 countries) shows AI-powered customer service fails at nearly 4x the rate of other AI applications.
• TELUS Digital/Ryan Strategic Advisory found only 32% of enterprises use AI-powered quality assurance and coaching tools.
