Bytedance's Volcano Engine announced the full launch of its newly released Doubao 1.5 Deep Thinking model on the edge large model gateway, offering users up to 5 million free tokens. This move has garnered significant attention in the AI field.

Researchers from Hong Kong and the UK have recently proposed a novel image tokenization method designed to convert images into digital representations (tokens) in a more compact and accurate manner. Unlike traditional methods that distribute information uniformly across all tokens, this method employs a hierarchical structure, capturing visual information layer by layer, thereby improving the quality and efficiency of image reconstruction. Traditional image tokenization techniques typically divide each part of an image equally into multiple tokens, whereas the new method adopts a hierarchical structure. Initial tokens encode rough shapes and structural elements,

Recently, a new AI model called "Quasar Alpha" quietly launched, attracting significant attention from the tech community and developers. Reportedly launched by an unnamed model lab, it's described as their first "stealth" model and a pre-release version of an upcoming long-context base model. Quasar Alpha quickly became a hot topic in the industry due to its impressive 1 million token context length, optimized encoding capabilities, and free and open access, pushing the boundaries of AI technology.

Google recently announced the official pricing for its Gemini 2.5 Pro API. For input tokens up to 200,000, the base price is $1.25 per million input tokens, approximately 9.1 RMB; while the price for every million output tokens is $10, approximately 72.9 RMB. For longer texts exceeding 200,000 input tokens, the input price adjusts to $2.50 per million, approximately 18.2 RMB.

Chinese AI startup DeepSeek quietly released its large language model, DeepSeek-V3-0324, sending ripples through the AI industry. The model, weighing in at 641GB, appeared on Hugging Face, showcasing DeepSeek's understated yet impactful style—a release with only an empty README file and model weights. Licensed under MIT, the model is free for commercial use and can run on consumer-grade hardware, such as a Mac equipped with an M...

The Lenovo ThinkSystem WA7785a G3 server has achieved a record-breaking throughput of 6708 tokens per second while running the 671B parameter DeepSeek large language model. This demonstrates the exceptional performance capabilities of the system for demanding AI workloads.

Along with the restoration of the recharge service, DeepSeek has also adjusted the pricing for some model calls. The promotional period for the deepseek-chat model has ended, and the pricing for its underlying V3 model has been adjusted to ¥2 per million input tokens and ¥8 per million output tokens. The pricing for the deepseek-reasoner model, based on the R1 model, is ¥4 per million input tokens and ¥16 per million output tokens.

Google Research recently announced the innovative 'Titans' series model architecture, achieving a groundbreaking 2 million token context length through bionic design, with plans to open-source related technologies in the future. The core innovation of this architecture is the introduction of a Deep Neural Long-Term Memory Module, inspired by the human memory system. Titans cleverly combines the rapid response capability of short-term memory with the persistence characteristics of long-term memory, while utilizing an attention mechanism to handle immediate context, forming an efficient information processing system.

In the field of artificial intelligence, ByteDance's commercial technology team presents the latest achievement, the Infinity model, which has become a new leader in the auto-regressive text-to-image generation domain with its outstanding performance and innovative technology. This newly open-sourced model not only surpasses Stable Diffusion 3 in image generation quality but also demonstrates significant advantages in inference speed. The core innovation of the Infinity model lies in its use of a Bitwise Token auto-regressive framework, which predicts the next level of resolution by +1 or -1.

On December 18th, at the Volcano Engine FORCE Power Conference, Volcano Engine President Tan Dai unveiled the new Doubao Visual Understanding Model. This model processes both text and image-related information simultaneously, providing more accurate answers. The new model excels in content recognition, understanding, and reasoning capabilities, featuring more nuanced visual description abilities, which brings stronger intelligent processing capabilities to enterprise users. Tan Dai revealed at the conference that the Doubao Visual Understanding Model has achieved significant technological breakthroughs and has also seen a dramatic reduction in pricing.

In the current field of artificial intelligence, precise control over language models has become crucial for developers and data scientists. Anthropic's Claude language models provide users with numerous possibilities, but effectively managing token usage remains a challenge. To address this issue, Anthropic has launched a brand new token counting API aimed at providing deeper insights into token usage, thereby enhancing the efficiency and control of interactions with language models. Tokens play a role in language models.

Elon Musk's xAI has finally fulfilled its promise from August by officially launching the API interface for its flagship AI model, Grok. However, this long-awaited API version feels somewhat rushed and basic. Currently, the xAI API only offers a model named "grok-beta." In terms of pricing, input tokens are charged at $5 per million tokens (approximately 750,000 words), while output tokens are charged at $15 per million tokens.
