Benchmark, the Silicon Valley venture firm that made early bets on hit consumer apps such as Snap, Twitter and Uber, is pushing into another trendy sector: artificial intelligence that can quickly generate complex text and images based on simple prompts.

Benchmark has been in talks to lead a seed funding of LangChain, according to two people who were briefed about it. LangChain software helps engineers build apps that use a type of machine learning model that powers OpenAI’s ChatGPT chatbot and that connect to information sources such as a database of customers.
