Anthropic Blocks Competitor Access, Ushering in the “Walled Garden” Era of AI: Anthropic has recently adopted an aggressive strategy by cutting off subscription access to Claude models for xAI, OpenAI, and third-party applications like OpenCode. This move has sent shockwaves through the industry and is interpreted as leading model manufacturers beginning to build moats to prevent competitors from using their models for “distillation” or internal development. Although Claude 3.7/4.5 excels in coding capabilities, this closed behavior may force other labs to accelerate their own development. This marks a shift in AI competition from a technical race to ecological blockades; developers should be wary of over-reliance on a single API, and the value of open-source models like DeepSeek will become further highlighted.

GPT-5.2 Solves Erdos Conjecture, AI-Driven Scientific Discovery Reaches New Milestone: Mathematics master Terence Tao confirmed that GPT-5.2 Pro successfully and autonomously solved Erdos problem #728. This is not only a victory for AI in closed mathematical systems but also demonstrates AI’s ability to rapidly rewrite and optimize academic discourse. By using Lean for formal proof, AI decouples complex mathematical concepts from the low cost of explanation, greatly enhancing scientific research efficiency. This foreshadows 2026 as the breakout year for AI for Science, where AI is no longer just an auxiliary tool but a “Digital Scientist” capable of constructing new abstractions and solving unsolved problems.

Tailwind CSS Lays Off 75%, Revealing Vulnerability of Open Source Business Models in the AI Era: The well-known CSS framework Tailwind CSS has encountered a serious financial crisis due to the popularity of AI coding assistants like Cursor. AI directly reads documentation to generate code, leading to a 40% drop in official website traffic and an 80% plunge in sales of paid components that rely on documentation traffic, forcing the team to lay off 75% of its staff. This event serves as a wake-up call for the open-source community: when AI becomes an agent that “freeloads” knowledge without generating clicks, traditional business conversion chains break. Currently, Cursor and Google have provided sponsorships to alleviate the crisis, but how open-source projects should charge “machine users” in the AI era remains an unsolved puzzle. (Source: 機器之心)
DeepSeek V4 Ready to Launch, Domestic Models Challenge Claude/GPT Hegemony: Market rumors suggest DeepSeek will release the V4 model in February, with programming capabilities expected to surpass Claude 3.7 and GPT-5.
