Mysterious Stealth AI Model 'Ox Alpha' Appears on OpenRouter
An unreleased AI model named Ox Alpha (also written '0x Alpha') has appeared on the OpenRouter model platform and in the open-source coding tool OpenCode, with no lab publicly claiming responsibility. The anonymous provider describes it as a reasoning model for programming tasks, long-running agent jobs and production workloads, and claims a context window of 1,048,576 tokens, a maximum output of 131,072 tokens, text/image/video input, and a daily capacity of 100 trillion tokens. The model is free to use for one week. Community forensics has pointed to Zhipu AI, Microsoft, Google, or Cursor/SpaceX as possible origins, but none are confirmed. Anonymous launches have become a common playbook; OpenRouter has previously hosted stealth listings later attributed to OpenAI, Xiaomi and Meituan. Ox Alpha reportedly processed about 7.1 trillion tokens in its first week across roughly 134,000 users. Independent benchmarks are still pending.
The anonymous AI model release is notable for the developer community but has no confirmed vendor or direct advertising/marketing application, limiting near-term AdTech impact.

AI Price War: OpenAI Gains Ground on Anthropic
The AI price war is intensifying, with OpenAI gaining significant ground on Anthropic among business customers. According to a Wall Street Journal report, spending on OpenAI and Anthropic models via the OpenRouter platform was nearly evenly split in September among roughly 120,000 companies using both, a shift from January when Anthropic held about 75% of that spending. OpenAI's aggressive price cuts on its GPT-5.6 lineup, including an 80% reduction on its smallest model Luna and 20% on Terra, are driving this change. Companies are increasingly prioritizing cost, combining multiple providers and using cheaper models for simpler tasks. Anthropic faces its own challenges, including capacity issues with Claude Code and data retention criticism. Both companies are preparing for IPOs, needing to demonstrate sustainable revenue to justify valuations exceeding $1 trillion.

US Government Excludes Microsoft from Visa Program
The US government has barred Microsoft from participating in the permanent residency process for foreign workers with H-1B visas, accusing the company of abusing the program. Vice President JD Vance stated that Microsoft laid off 6,000 American employees last year while benefiting from 6,300 H-1B visa holders. The Department of Labor, led by Keith Sonderling, will not accept new permanent residency applications from Microsoft, as well as several consulting firms and Adobe. This action comes weeks before the midterm elections and reflects the Trump administration's broader criticism of the H-1B program, which it claims disadvantages American workers. Microsoft has not yet responded. The move could impact the tech industry's ability to retain skilled foreign talent.
