Meta's latest research introduces the Agent-as-a-Judge framework, an innovative method for agent evaluation aimed at assessing and optimizing other agents' performance through the agents themselves. Traditional methods of agent evaluation often rely on final outcomes or extensive human effort, while Agent-as-a-Judge introduces an intermediate feedback mechanism to ensure precise evaluation and optimization at every stage of the task. The framework has performed exceptionally well in experiments. It achieved a 90.44% alignment rate with human expert evaluations, far surpassing the traditional LLM-as-a-Judge method. Additionally, Agent-as-a-Judge is significantly more efficient than human evaluators, completing 55 tasks in just 118.43 minutes at a total cost of only $30.58. The article also introduces the DevAI dataset, a new benchmark containing 55 real-world AI development tasks, designed to serve as a proof-of-concept testing platform for Agent-as-a-Judge. The DevAI dataset not only focuses on the final results of tasks but also tracks and evaluates each stage of task execution, providing more comprehensive feedback.

Alibaba International's AI team recently open-sourced the multimodal large model Ovis1.6. This model demonstrates exceptional performance on the OpenCompass benchmark, a comprehensive evaluation standard for multimodal models. Notably, Ovis1.6 outperforms the closed-source GPT-4o-mini in tasks such as mathematical reasoning and visual understanding. The core principle behind Ovis1.6 lies in structurally aligning visual and text embeddings. It comprises three key components: a visual tokenizer, a visual embedding table, and an LLM. Drawing inspiration from text embedding approaches used in large language models, Ovis introduces a learnable visual embedding table. This table converts continuous visual features into probabilistic visual tokens, which are then indexed and weighted multiple times by the visual embedding table to produce structured visual embeddings. For text processing, Ovis adopts the standard approach employed by current large language models, transforming input text into one-hot tokens. Subsequently, it retrieves the corresponding embedding vectors for each text token based on the text embedding table. Finally, Ovis concatenates all visual embedding vectors with text embedding vectors and processes them through a Transformer to accomplish multimodal tasks. Building upon Ovis1.5, Ovis1.6 further enhances its high-resolution image processing capabilities. It leverages a larger, more diverse, and higher-quality dataset for training, and optimizes the training process through a DPO fine-tuning approach that follows instructions. Architecturally, Ovis1.6 employs a dynamic subnetwork solution, enabling flexible handling of image features across different resolutions. This enhances the model's ability to tackle complex visual tasks. In terms of data, Ovis1.6 incorporates diverse datasets during training, including Caption, OCR, Table, Chart, and Math, ensuring its proficiency across a wide range of application scenarios. Regarding training strategies, Ovis1.6 continuously optimizes model performance using DPO and other schemes. This enhances the model's ability to generate text and understand complex instructions, leading to further improvements in its performance on complex tasks.
