Hugging Face has released a blog post on how to fine-tune Stable Diffusion models using the Trust Region Loss (TRL) and Deep Deterministic Policy Gradients Optimizer (DDPO). This method allows for more stable training of large language models. According to Hugging Face, this approach can be used with their Transformers library. --- Why it matters: This matters because it provides a new way to fine-tune large language models like Stable Diffusion, which could improve their performance and stability in tasks such as image generation and text-to-image synthesis.
