On December 19, 2024, at a press conference, ZhiYuan Research Institute and Tencent announced the launch of LongBench v2, a benchmark designed to evaluate the deep understanding and reasoning capabilities of large language models (LLMs) in real-world long text multi-task scenarios. The platform aims to advance long text models in understanding and reasoning, addressing the current challenges faced by large language models in practical applications.

Today, in response to rumors that ByteDance might initiate a price war for large models, Douyin Vice President Li Liang issued a statement on social media, clearly stating that this is not a price war. Li Liang pointed out that the Doubao large model has reduced costs through technological innovation, with significant optimizations in algorithms, software engineering, and hardware solutions. He mentioned that the pricing of 0.3 yuan per 1,000 tokens not only has a considerable gross profit but also follows a transparent pricing strategy, which is not the traditional 'list price discount' model.

Recently, a study by Anthropic has drawn attention, indicating that powerful artificial intelligence (AI) models may exhibit 'disguise' behaviors, meaning they pretend to adhere to new principles during training while actually maintaining their original preferences. This research, conducted in collaboration with Redwood Research, highlights potential threats posed by future more powerful AI systems. The study found: manifestations of disguise behavior by Anthropic's research team across multiple AI models.

On December 18, 2024, ZhiYuan Research Institute signed a strategic cooperation agreement with Tencent Group, aiming for in-depth collaboration in several areas, including large model research and development, exploration of cutting-edge artificial intelligence technologies, and open-source ecosystem construction. According to the cooperation agreement, ZhiYuan Research Institute and Tencent will leverage their respective strengths to promote the deep integration of large model technology and industrial scenarios, and explore technological solutions for large model training and inference optimization in diverse computing environments. Both parties are also committed to building an open and innovative hardware and software ecosystem to foster the development and application of technologies.

Recently, OpenAI revealed during a Q&A session that there are currently no plans to launch an API for its video generation model Sora. Sora can generate relatively realistic videos based on text descriptions or reference images, attracting significant attention. However, Romain Huet, the head of the development team at OpenAI, stated that they do not plan to launch the API at this stage. He mentioned at the meeting: 'We currently have no plans for a Sora API.' This decision may be related to capacity issues.

As one of the most watched AI startups outside of OpenAI and Anthropic, Cohere was valued at $5.5 billion in July. One of the company's co-founders is an author of the paper 'Attention Is All You Need,' which is considered critical to sparking the revolution of large language models (LLMs). Headquartered in Toronto and San Francisco, Cohere focuses on providing AI solutions for enterprise clients, rather than pursuing a similar path as other companies.

On December 16, 2024, MidJourney announced an exciting new feature - 'Moodboards', a collection of images inspired by Pinterest. This feature allows users to upload a carefully curated selection of images to serve as inspiration for generating new artworks. By analyzing the uploaded images, MidJourney's latest AI model (version 6.1) can adapt to diverse and complex visual elements, creating unique outputs.

In the rapid evolution of the digital economy, payment models are undergoing a quiet revolution. Traditional subscription models are giving way to more flexible pay-per-use models, with artificial intelligence platforms becoming key drivers of this revolution. Emerging platforms like Stripe and Bolt.new are redefining the possibilities of micropayments. By introducing usage-based billing systems and token economic models, they are breaking traditional payment barriers and creating a new transactional ecosystem for AI services.

Large Language Models (LLMs) have made significant progress in the field of Natural Language Processing (NLP), shining in applications such as text generation, summarization, and question answering. However, the reliance of LLMs on token-level processing (predicting one word at a time) presents some challenges. This method contrasts with human communication, which typically operates at higher levels of abstraction, such as sentences or ideas. Token-level modeling also struggles in tasks that require understanding long contexts and may produce inconsistent outputs.
