Modal Labs, an AI inference infrastructure provider, is reportedly nearing completion of a $750 million funding round led by Accel, which would value the company at $15.75 billion post-money, sources said. This new funding is expected to more than triple Modal's valuation in just four months, following its previous funding round announced four months ago at a $4.65 billion valuation. The deal comes amid a surge in demand for AI inference services, particularly from clients relying on open-source models.
