HuggingGPT is the most interesting paper I read this week. It gets very close to the "Everything App" vision that I described a while ago. ChatGPT acts as a controller over the *AI model space*, picks the right model (app) given the human specification, and assembles them correctly to solve the task. It's multimodal in a "low-bandwidth" way - all modalities need to be compressed and connected through text strings. HuggingGPT is also related to Prismer's idea: leverage pre-trained domain expert models as much as possible. Sometimes training less is doing more!
