Thrilled to welcome Jeff and the Chroma team to Replit! They’re pioneers in AI. They were building RAG before it was even a thing! At Replit, they’ll help solve one of the hardest problems in AI: giving agents the context and memory they need to do real work. Massive step toward the self-driving company.
