Field notes

InferenceGenesis structures its introduction around a small character-level language model rather than a black-box demonstration. The stated workflow uses Shakespeare text, maps characters to numbers, trains the model while displaying loss, and then generates text. The homepage reports 3,225,665 trainable numbers, 65 possible characters, and a 1 minute 36 second laptop training time. Nine short films accompany the five-step executable course.
