Chinese AI lab DeepSeek has unveiled preview versions of its latest large language model, DeepSeek V4, which serves as a major update to its previous V3.2 model and the accompanying R1 reasoning model. The company's new offerings, DeepSeek V4 Flash and V4 Pro, are described as mixture-of-experts models, each boasting a substantial context window of 1 million tokens. This impressive capacity is intended to facilitate the processing of extensive codebases or documents within prompts.
The V4 Pro model, in particular, stands out with a total of 1.6 trillion parameters and 49 billion active parameters, making it the largest open-weight model currently available. The mixture-of-experts approach employed in these models is designed to optimize performance by activating only a specific subset of parameters for each task, thereby reducing inference costs.
DeepSeek's V4 Pro model, with 1.6 trillion total parameters and 49 billion active, is positioned as the largest open-weight model, challenging the efficiency and capabilities of established frontier AI systems.
China’s DeepSeek previews new AI model a year after jolting US rivals - The Verge
DeepSeek, a prominent Chinese AI company, has released a preview of its highly anticipated next-generation AI model, V4. The company asserts that this open-source model is capable of competing directly with leading closed-source systems from major US rivals such as Anthropic, Google, and OpenAI. This launch comes approximately a year after DeepSeek made headlines with its R1 model, which it claimed was trained at a fraction of the cost of comparable US systems.
The V4 model represents a significant leap forward from previous iterations, particularly in its coding capabilities. This focus on coding is crucial for the development of advanced AI agents and has been a driving force behind the success of tools like ChatGPT Codex and Claude Code. Notably, DeepSeek has emphasized the V4 model's compatibility with domestic Huawei technology, highlighting advancements in China's chip industry.
Despite the excitement surrounding V4, DeepSeek has not disclosed the training costs or the specific hardware utilized for its development. The company has faced previous accusations, including allegations from US officials of using banned Nvidia chips and claims from Anthropic that DeepSeek misused Claude to enhance its products.
DeepSeek's V4 model aims to directly challenge US AI leaders with enhanced coding capabilities and explicit compatibility with Huawei technology, marking a significant milestone for China's AI and chip industries.
OpenAI releases GPT-5.5, bringing company one step closer to an AI ‘superapp’ - TechCrunch
OpenAI has officially launched GPT-5.5, its latest artificial intelligence model, which the company hails as its "smartest and most intuitive to use model" to date. According to OpenAI co-founder and president Greg Brockman, this new algorithm brings the company closer to its ambitious goal of creating an OpenAI "superapp."
During a call with journalists, Brockman highlighted GPT-5.5 as a substantial step toward "more agentic and intuitive computing." He emphasized that the model is a "faster, sharper thinker for fewer tokens compared to something like 5.4," which translates to greater access to frontier AI for both businesses and consumers. This release reinforces OpenAI's commitment to advancing AI capabilities and making them more accessible.
OpenAI's GPT-5.5 is a strategic leap towards an AI 'superapp,' designed for more agentic and intuitive computing with increased capabilities and efficiency, as stated by co-founder Greg Brockman.
OpenAI's GPT-5.5 is here, and it's no potato: narrowly beats Anthropic's Claude Mythos Preview on Terminal-Bench 2.0 - VentureBeat
After much anticipation and internal codenames, OpenAI has officially unveiled GPT-5.5, its newest large language model. This release aims to solidify OpenAI's position at the forefront of generally available LLMs. Benchmark results from Terminal-Bench 2.0 show that GPT-5.5 narrowly outperforms Anthropic's Claude Mythos Preview, a private model, indicating a strong performance against top rivals like Anthropic and Google.
Amelia "Mia" Glaese, VP of Research at OpenAI, highlighted GPT-5.5's exceptional strength in coding, a claim backed by both benchmarks and partner feedback. Greg Brockman, OpenAI co-founder and president, further emphasized the model's intuitive nature and its ability to operate with less guidance, stating it can "look at an unclear problem and figure out what needs to happen next." He noted significant gains in coding, broader computer work, and scientific research applications.
GPT-5.5 is available in two variants: GPT-5.5 and GPT-5.5 Pro. While the standard version caters to general intelligence tasks, the Pro model is specifically engineered for high-stakes environments such as legal research, data science, and advanced business analytics, offering enhanced precision and specialized logic. OpenAI CEO and co-founder Sam Altman reiterated the company's philosophy on X, stating, "We want our users to have access to the best technology and for everyone to have equal opportunity."
