CODEFUSION: A Pre-trained Diffusion Model for Code Generation

Fusion 360 Workflows: Programming CAM

This is great! Training a tiny 11M parameter character-level text diffusion model! It's a WIP but the code is currently a heavily modified nanochat gpt implementation (to change from autoregressive decoding to diffusion) and trained on the Tiny Shakespeare dataset. The naive implementation of a masking schedule is having a uniform masking probability for each token for each iteration. Newer approaches mask in block chunks from left to right which improves output quality and allows some KVCache r
