Amazon has introduced Titan Image Generator, an AI model that allows developers to create realistic, studio-quality images using natural language prompts. Aimed at enterprise users, the model can generate images with "inclusive attributes and limited distortions", according to AWS. It offers features such as automatic image editing, inpainting, and outpainting. Developers can also customize the model with proprietary data to generate images that conform to brand guidelines or specific styles. Titan Image Generator adds invisible watermarks to all images to reduce the spread of misinformation and allows users to verify the origin of the image through an API. The model is not a standalone app or website, but can be built upon by developers with access to Amazon Bedrock.

Hugging Face has developed the highly optimized Zephyr-7B mini-language model based on Mistral 7B, an open-source model from European start-up Mistral AI. The model was refined using a method called Distilled Supervised Fine-Tuning (dSFT), which uses the output of a larger "teacher" model to train a smaller "student" model. The Distilled Direct Preference Optimization (dDPO) method uses AI feedback from a set of teacher models as preference data, significantly reducing training time and resources required. Zephyr-7B is just ahead of Mistral 7B in benchmarks and can even come close to Llama-2 with 70 billion parameters. You can test the model here in chat.
