Description

HunyuanCustom is an advanced framework for generating customized videos across multiple modalities, focusing on maintaining subject consistency while accommodating conditions related to images, audio, video, and text. This framework builds on HunyuanVideo and incorporates a text-image fusion module inspired by LLaVA to improve multi-modal comprehension, as well as an image ID enhancement module that utilizes temporal concatenation to strengthen identity features throughout frames. Additionally, it introduces specific condition injection mechanisms tailored for audio and video generation, along with an AudioNet module that achieves hierarchical alignment through spatial cross-attention, complemented by a video-driven injection module that merges latent-compressed conditional video via a patchify-based feature-alignment network. Comprehensive tests conducted in both single- and multi-subject scenarios reveal that HunyuanCustom significantly surpasses leading open and closed-source methodologies when it comes to ID consistency, realism, and the alignment between text and video, showcasing its robust capabilities. This innovative approach marks a significant advancement in the field of video generation, potentially paving the way for more refined multimedia applications in the future.

Description

Reka Flash 3 is a cutting-edge multimodal AI model with 21 billion parameters, crafted by Reka AI to perform exceptionally well in tasks such as general conversation, coding, following instructions, and executing functions. This model adeptly handles and analyzes a myriad of inputs, including text, images, video, and audio, providing a versatile and compact solution for a wide range of applications. Built from the ground up, Reka Flash 3 was trained on a rich array of datasets, encompassing both publicly available and synthetic information, and it underwent a meticulous instruction tuning process with high-quality selected data to fine-tune its capabilities. The final phase of its training involved employing reinforcement learning techniques, specifically using the REINFORCE Leave One-Out (RLOO) method, which combined both model-based and rule-based rewards to significantly improve its reasoning skills. With an impressive context length of 32,000 tokens, Reka Flash 3 competes effectively with proprietary models like OpenAI's o1-mini, making it an excellent choice for applications requiring low latency or on-device processing. The model operates at full precision with a memory requirement of 39GB (fp16), although it can be efficiently reduced to just 11GB through the use of 4-bit quantization, demonstrating its adaptability for various deployment scenarios. Overall, Reka Flash 3 represents a significant advancement in multimodal AI technology, capable of meeting diverse user needs across multiple platforms.
