The models are built on a decoder-only transformer architecture and have been pretrained with a significant amount of data, including a multimodal mix of 4 trillion tokens for the 8B model and 2 trillion tokens for the 70B model. This extensive training allows Apertus 1.5 to process and generate text from images, audio, and text inputs, offering developers new possibilities for creating innovative applications.
Apertus 1.5 is designed with responsible development in mind, respecting data owners' opt-out consent and employing methods to prevent memorization of training data. The models are fully open, with open weights, data, and training details available to the public, ensuring transparency and accessibility.
The models also introduce a 'thinking mode' that enhances their reasoning capabilities, allowing for more accurate and contextually aware responses. This feature, combined with improved instruction-following and tool-use capabilities, makes Apertus 1.5 a powerful tool for developers looking to integrate advanced AI functionalities into their projects.
Deployment of Apertus 1.5 is supported in open-source frameworks like Transformers and vLLM, with detailed instructions available for getting started. The models are available for use in both desktop and cloud environments, providing flexibility for various deployment scenarios.
