ekzhang1 announces he's back at Modal after a year at Thinking Machines, where he worked on ML and production systems, new kernels for training/inference, scaling research infra, fast interaction models and RL dynamics. He joined as the youngest of 60 employees among ex-OpenAI/Meta/GDM/Mistral folks, and notes the company has reinvented itself many times and looks to be on a good path after recent releases.
