   Soumith Chintala says Inkling 2 Small is built for customizability

   AISoumith Chintala says Inkling 2 Small was built to be customizable, a property the team studied before training. He says that for a fixed data and dollar budget, the model delivers relatively strong results compared with other options. He adds that customizability is a launch-blocking eval, and he invites readers to try the model through Tinker.
