Arcweld

Arcweld is a server for the primary goal of rapidly and efficiently experimenting with open weights models, with secondary goals of 1) researching novel LLM inference technologies 2) reducing the cost of using hosted APIs when it would not interfere with the primary goal. It is not intended for training since it isn't the ideal way to purchase memory bandwidth per dollar (critical for training), although it isn't forbidden.
