CODEFUSION is a new innovative model from Microsoft that use diffusion model for code generation.
In this video we dive into the research paper that introduce the model, titled: "CODEFUSION: A Pre-trained Diffusion Model for Code Generation", to understand why it is needed, how it works, and well does it perform.

We start by providing a recap for what are diffusion models, which are the backbone architecture for the top text-to-image generation models, such as Stable Diffusion. 

But how does it work for code? 
We explain the CODEFUSION model architecture and show how it is built in order to generate code using text prompt, and explain how it is being trained.

Finally, we review interesting results from the paper that show the potential of this innovative approach.

CODEFUSION is a Microsoft research model that applies diffusion-based generation to code, allowing iterative refinement unlike traditional autoregressive code LLMs. It uses a pre-trained CodeT5 encoder, a denoiser operating in latent space, and a decoder to produce code tokens. Trained in two phases (unsupervised pre-training and supervised fine-tuning), CODEFUSION achieves competitive results against much larger models like GPT-3 and ChatGPT, outperforming them on top-3 and top-5 accuracy metrics across Python, Bash, and Excel formula benchmarks despite being significantly smaller.
